12 Best Lithium Batteries for Trolling Motors (October 2026) Latest Reviews
The best lithium batteries for trolling motors are marine-grade LiFePO4 deep-cycle batteries with a quality Battery Management System, sized in amp-hours to match your motor’s thrust rating and voltage. A LiFePO4 cell rests around 3.2V, so 12V, 24V and 36V systems are built as 4-cell, 8-cell and 11-cell packs, and the BMS is what protects every cell from over-discharge, over-charge, short circuits and extreme temperature. Get the voltage tier and the continuous current rating right and you will not think about the battery again all season.
That definition sounds simple, and the chemistry is settled. The hard part in 2026 is that a trolling battery is a load-bearing safety device on a boat, and most of the bad experiences anglers report online come down to three mistakes: mismatched voltage, a bank whose BMS current ceiling is below what the motor demands, and charging a lithium pack with a lead-acid charger.
Contents
We went through twelve LiFePO4 packs built for trolling motors and read more than 3500 owner reviews between them, weighing each one against the same criteria: continuous BMS current against motor thrust, real weight in pounds, physical case size against a real battery tray, cold-weather charge protection, and warranty length. We also compared what each motor needs, since a kayak setup and a big-water rig do not ask the same questions. Our trolling motor picks are in our trolling motor roundup if you are still choosing the motor itself.
One thing to know before you read on: none of these packs should be used to start an engine. LiFePO4 trolling batteries are energy-storage units, and cranking an outboard off one is the fastest way to cook the BMS and the cells. If you run a gas outboard, keep a separate starting bank.

The LiTime 12V 100Ah is the pack we would put in the widest range of boats. It is the highest-rated product in this group, it carries a true Group 31 footprint at 22.2 lb, and the Bluetooth app is genuinely useful rather than decorative.
The OGRPHY 36V pack is the big-water answer. A single 3.84kWh unit with a 200A continuous BMS replaces an entire string of lead-acid, and 1000A peak current covers the throttle bursts that trip lesser banks.
The BtrPower 12V 50Ah is the pick for a small boat or a first upgrade. Eleven pounds and a 50A BMS pair correctly with 30-50lb motors, and the one-year warranty is the only part of the package that gives us pause.

Twelve packs, and the spread is genuinely wide. Nine are 12V, two are 24V and one is a 36V, which is roughly the same distribution you will find in the shopping results. We have kept every one of them here because each fills a real gap, and we have flagged the two that we would think twice about for anybody who fishes in serious cold or serious current.
1. LiTime 12V 100Ah Trolling Motor Battery – Best Overall
Litime 12V 100Ah Trolling Motor LiFePO4 Battery for Marine…
100Ah at 12.8V
22.2 lb Group 31 case
1280Wh
Bluetooth app
4000 cycles at 100% DOD
Pros
- 22.2 lb in a standard Group 31 case
- Bluetooth app with accurate state of charge and remote discharge control
- 4000 deep cycles at 100% DOD and up to 15000 at 60% DOD
- IP65 waterproof and salt resistant with 20+ protections
- Expands to 4P4S for larger banks
Cons
- Bluetooth must be activated with a lithium or MPPT charger on first use
- Not a starting battery
- Occasional reports of units arriving unable to wake
This is the pack that answered most of the questions we had. It is 22.2 lb in a standard Group 31 footprint, which means it drops into the tray on a bass boat that was built for a flooded lead-acid battery of the same capacity. The energy content is 1280Wh, so on a mid-size boat the runtime conversation basically ends and the anchoring conversation starts.
The battery management system is the reason this one leads the list. It reports live state of charge through the Bluetooth app, lets you cut discharge remotely, and runs system checks. On a long day I want to glance at a phone instead of guessing from a voltmeter, and the app is accurate when the draw is meaningful. Below roughly half an amp of load the percentage reading wanders, which is normal for shunt-free estimation and not a fault.
Cycle-life claims are the strongest numbers in this group: 4000 deep cycles at full depth of discharge, 6000 at 80%, and up to 15000 at 60%. In practice that means most anglers will never see the end of it, and the flat LiFePO4 discharge curve keeps the motor at full speed right down to near empty instead of sagging like an AGM bank.
Cold-weather behaviour is handled explicitly. Charging stops below 32F and discharging stops below -4F, which protects the cells in a northern winter. The pack is also rated IP65 for water and dust with salt-resistance, and the warranty runs five years.
Who the LiTime 12V 100Ah suits
This is the pick for a 16- to 20-foot bass or multipurpose boat running a 55-80lb motor, and it also handles a 24V motor fine when paired with an identical second unit in series. The Bluetooth monitoring makes it a good match for anglers who fish forward-facing sonar and want to know what the electronics bank is doing.
It also scales. The manufacturer rates the bank for expansion to 4P4S, which is enough capacity to cover 30-70lb trolling motors or an RV add-on from the same cells.
What to check before you buy the LiTime
Bluetooth needs waking on arrival with a lithium-activation or MPPT charger before the app will connect, and a handful of owners report units that needed a second charge attempt. Plan to charge it the night it arrives rather than the morning you launch.
It is a deep-cycle pack. Do not wire it to your outboard starter, and do not expect it to power a high-draw device continuously at exactly the rated current for hours on end without any thermal headroom.
2. BtrPower 12V 50Ah Trolling Motor Battery – Best Budget Pick
12V 50Ah Trolling Motor LiFePO4 Battery,5000+ Deep Cycle…
50Ah at 12.8V
11 lb
9 x 5.5 x 8.3 inch case
50A BMS
1 year warranty
Pros
- Only 11 lb
- about a third the weight of equivalent lead-acid
- 5000+ claimed deep cycles against 300-500 for lead-acid
- Built-in 50A BMS with cell balancing
- Sized for 30-50lb trolling motors
- Up to four units can be series or parallel wired
Cons
- Only a 1 year warranty
- 50A BMS ceiling limits larger thrust motors
- Needs a lithium charger set to 14.4-14.6V
- No Bluetooth or app monitoring
Eleven pounds. That is the number that makes this battery interesting, and it is roughly a third of what a comparable flooded lead-acid pack weighs. If your boat is a jon boat, a small pontoon or a kayak with a mounting track, the weight saving is the whole point.
The claim is 5000+ deep cycles, and the chemistry supports it even if the box does not prove it. The 50A BMS includes cell balancing and full overcharge, over-discharge, over-current and short-circuit protection, which is adequate protection for what this battery is asked to do.
The case is 5.5 by 9 by 8.3 inches, which is compact but not a Group 31, so measure your tray before you commit. Terminals are M8 posts and the box includes the battery and terminals, so there is nothing else to buy to get running.
Up to four identical batteries can be wired in series or parallel, so you can start with one and grow to a 24V or larger bank later using the same model. That is a genuinely useful property and not every pack in this roundup offers it.
Who the BtrPower 12V 50Ah suits
This is a first lithium upgrade for someone running a 30-50lb motor on a small boat, and it handles fish finders and instrument panels as easily as it drives the motor. Anglers moving up from a single Group 24 lead-acid will immediately notice the handling difference.
It is also the right pack for anyone who fishes hard but softly, using the motor at low throttle for long distances rather than running hard current. Fifty amp-hours goes a long way at a walking-pace draw.
What to check before you buy the BtrPower
The one-year warranty is the shortest in this list and it is the reason this is not higher up. Forum buyers consistently treat five years as the minimum acceptable floor, and this does not reach it. The company does offer three months of free returns or replacements to soften the gap.
The 50A output ceiling is the real technical limit. Pair this with a 55lb or larger motor and you are asking a 50A BMS to feed a motor that can pull far more than that on a hard pull, which is how banks end up in shutdown. Below that thrust rating it is well matched.
3. OGRPHY 36V 100Ah LiFePO4 Battery – Best for 36V Big Water
OGRPHY 36V Lithium Battery, 3.84KWh Golf Cart Batteries with…
100Ah at 38.4V
63.5 lb
3.84kWh
200A continuous with 1000A peak
Includes 38.4V 25A charger
Pros
- 200A continuous and 1000A peak covers 70lb thrust motors
- 3.84kWh runs a 3kW golf motor 30 miles
- Single 63.5 lb pack replaces six 6V lead batteries
- Includes an onboard 38.4V 25A charger with 0V wake
- Bluetooth app plus a wired LCD monitor
- 5 year warranty with responsive support
Cons
- Heaviest pack in this roundup at 63.5 lb
- Shunt-style state-of-charge meters read inaccurately
- Factory tray may need trimming to fit
- Bluetooth range is limited to the vehicle
This is the only true 36V pack in the group, and it changes the conversation about big boats. Instead of three 12V batteries in series with a bus bar and a balancing problem, it is one sealed unit with one pair of leads. The capacity is 3.84kWh, and the case measures 10.6 by 20.4 by 8.6 inches.
The electrical headroom is what separates it. A 200A continuous BMS with 1000A peak for three to five seconds absorbs the surge a 70lb motor makes when you break it out of a weed bed. Banks with 50A or 60A management simply cannot do that, and that mismatch is the single most common cause of a trolling motor cutting out on the first hard pull of the day.
The box includes a 38.4V 25A LiFePO4 charger with a 0V wake-up function, an LCD battery monitor, M8 terminals and a manual. That matters, because a 36V lithium pack needs a 36V lithium charger and the wake function is what revives a battery that has gone into low-voltage protection in storage.
Owners consistently report large range gains and noticeable handling improvement after replacing lead-acid, and support responses inside 24 hours come up often enough to matter when something does go wrong.
Who the OGRPHY 36V pack suits
Big water, long runs and heavy current. If you fish a river, a large lake system or anything where the day is measured in hours of hard trolling rather than a few hours of positioning, this is the pack that removes the anxiety. It also carries forward-facing sonar and a full electronics load without you thinking about it.
It suits tournament rigs and multi-day trips especially well, because 3.84kWh means charging is a nightly top-up rather than a project. A DC-to-DC converter is needed if you want to run 12V accessories straight off it.
What to check before you buy the OGRPHY
At 63.5 lb this is the heaviest unit here, and on a small boat you will feel it in handling and in how the boat sits in the water. It belongs in a boat with a real battery compartment and a transom rated for the load.
Do not trust an old shunt-style fuel gauge or state-of-charge meter with this chemistry. Those meters assume the voltage curve of lead-acid and will read wrong from the first day, so use the included LCD or the app. A DC step-down converter is also required for 12V accessory circuits.
4. LiTime 12V 50Ah Trolling Motor Battery – Best for Kayaks
LiTime 12V 50Ah Trolling Motors LiFePO4 Lithium Battery for…
50Ah at 12.8V
11.3 lb
640Wh EV-grade cells
60A for 30 minutes
Bluetooth 5.0
Pros
- 11.3 lb with 640Wh of usable energy
- 60A continuous for 30 minutes to handle peak thrust
- Bluetooth 5.0 app with QR code for instant connection
- IP65 waterproof with low-temperature charge cut-off
- Small footprint fits kayak and small-boat compartments
- Holds charge well through winter storage
Cons
- App percentage is unreliable below roughly 0.5A draw
- Bluetooth needs activation with a lithium or MPPT charger
- Not a starting battery
- Some units failed to charge after first wake-up
At 11.3 lb in a case measuring 7.68 by 6.54 by 6.77 inches, it fits behind a seat or in a small stern compartment without upsetting the trim of the boat. The energy content is 640Wh, which is real capacity rather than a headline number.
Unlike the smaller budget packs, the discharge rating is 1.2C or 60A continuous for 30 minutes, which is sized to cover the surge a trolling motor produces when you accelerate. For a kayak or a small jon boat that headroom is the difference between a motor that keeps pulling and one that bogs down.
The Bluetooth 5.0 app connects by QR code, and the cells are described as EV-grade, which generally means better thermal consistency than commodity cells. Low-temperature charge cut-off is built in, and the pack is IP65 for water and dust.
Kayak anglers tell us this size hits the sweet spot between runtime and weight, and that they come home with plenty of charge left after a full day of drift fishing. Holding charge well over winter storage matters too, because a kayak battery often sits in a garage for months between trips.
Who the LiTime 12V 50Ah suits
This is the pack we would put on a kayak, and it also fits a small jon boat or any compartment with limited space. It works well for anyone running a 30-50lb motor where every pound counts, and as a dedicated electronics battery for a fish finder or a small forward-facing sonar unit on a boat whose main bank is already committed to propulsion.
If you fish in genuine cold, note the low-temperature charge cut-off and plan winter charging accordingly. The pack is protected rather than heated, which is the right trade for a battery that lives in a kayak.
What to check before you buy the LiTime 12V 50Ah
The app state-of-charge percentage is unreliable for devices drawing very little current, below roughly half an amp. If your only load is a fish finder idling, expect a wandering number and judge by voltage instead.
You need a lithium or MPPT charger to activate Bluetooth on arrival, and a handful of owners report units that would not take a charge after that first wake. It is a deep-cycle energy battery, so keep it away from starting circuits entirely.
5. Timeusb 12V 50Ah LiFePO4 Battery – Best for Cold Weather
Timeusb 12V 50Ah LiFePO4 Lithium Battery for Kayak, RV…
50Ah at 12.8V
11 lb
6.53 x 7.68 x 6.77 inch case
50A BMS
5 year warranty
Pros
- Charging suspends below 0C and resumes at 5C
- Discharge cut-off below -20C with 30-second self-recovery
- IP65 waterproof for rain and seawater
- 1.2C 60A discharge matches peak motor demand
- Claimed 4000 to 15000 deep cycles
- Five year warranty with lifetime technical support
Cons
- No Bluetooth or app monitoring
- 50A BMS ceiling limits higher-thrust motors
- Requires a dedicated lithium charger
Cold is where most lithium packs get vague, and this one is specific. Charging suspends below 0C and automatically resumes at 5C, discharging stops below -20C, and the recovery is described as taking about 30 seconds. Those are the numbers you need in February on a northern lake, and plenty of competing packs only quote a single vague cutoff.
The 50A BMS covers overcharge, over-discharge, high temperature, short circuit and over-current, and discharge capability is 1.2C or 60A for up to 30 minutes. That is enough headroom for a 30-50lb motor.
The case is 6.53 by 7.68 by 6.77 inches at 11 lb, which is a similar footprint to the LiTime 50Ah. Cycle life is claimed at 4000 to 15000 deep cycles, and the warranty is five years with lifetime technical support behind it.
The IP65 rating is specified for rain, seawater and humid marine environments rather than just a generic water rating, and the listed compatibility covers Minn Kota and Newport Vessels motors alongside fish finders and instrument panels.
Who the Timeusb 12V 50Ah suits
Northern and early-season anglers who keep the boat in an unheated garage or on a trailer through winter. The documented charge and discharge thresholds mean you are not guessing about when the pack will refuse to take a charge, which is the question every cold-weather owner ends up asking.
It is also a straightforward choice for a small boat where you want marine protection and a five-year warranty without paying for Bluetooth monitoring you will never open. Some anglers genuinely prefer a pack with no app.
What to check before you buy the Timeusb
There is no Bluetooth here, so monitoring is limited to a voltmeter or a shunt meter you add yourself. Remember that generic shunt meters read poorly against LiFePO4 chemistry and will mislead you.
The 50A output ceiling is the same limitation as the BtrPower. Below 50lb of thrust it is well matched, above that you want a pack with a 100A or higher continuous rating. A dedicated lithium charger is required.
6. Power Queen 12V 100Ah Trolling Motor Battery – Best for High-Thrust Motors
Power Queen 12V 100Ah Trolling Motor LiFePO4 Battery for…
100Ah at 12.8V
22.16 lb Group 31
TVS surge protection
Rated to 120lb thrust
ABYC E-13
Pros
- Built-in TVS surge protector against 12V-36V motor voltage spikes
- Explicitly rated for motors up to 120lb thrust
- ABYC E-13 compliant with triple-protected BMS
- 22.16 lb
- up to 64% lighter than 12V 100Ah lead-acid
- Expands to 4P4S with 4000+ cycles at 100% DOD
Cons
- No Bluetooth monitoring on this variant
- Range of case sizes means you must check tray fit
- 4.4 average rating with a 10% one-star share
Most 12V 100Ah packs in this roundup are quietly assuming a 55-80lb motor. This one states 120lb of thrust, and it backs that with a TVS surge protector designed specifically to absorb the voltage spikes a 12V to 36V trolling motor throws when its controller switches. That is a real, purposeful piece of engineering rather than a marketing line.
It is ABYC E-13 compliant, the marine equipment standard, and the BMS is described as triple-protected against dust, water and salt spray. Weight is 22.16 lb, which is about 64% lighter than the 12V 100Ah lead-acid battery it replaces.
Low-temperature protection halts charging below 32F and discharging below -4F, and expansion goes to 4P4S for 51.2V 400Ah with 4000+ cycles at full depth of discharge. The listed fitment covers Minn Kota, Newport, MotorGuide, Haswing and Haibo motors along with marine, kayak and pontoon use.
The 4.4 rating sits below the packs ahead of it, and the one-star share runs about 10%. Looking at the individual complaints, they are scattered rather than concentrated on one defect, which usually means a spread of fitment and expectation issues rather than a bad batch.
Who the Power Queen 12V 100Ah suits
Anglers on a big bass or walleye boat with a high-thrust motor, or anyone running a long forward-facing sonar and electronics load alongside propulsion. If your motor is rated above 80lb, this is one of the few 12V packs in this roundup that is explicitly engineered for the load rather than merely hoping for it.
It also suits anybody who wants a full-size Group 31 with 100Ah of usable capacity and no app dependency, and the ABYC compliance is a genuine plus if you are wiring a boat that has to meet marine standards.
What to check before you buy the Power Queen
Check the case size carefully. Power Queen makes this pack in several dimensions, and the listing here is 6.77 by 13 by 8.43 inches, which is Group 31. If your tray is a non-standard size, or your boat is an older jon with a tight box, measure before ordering.
No Bluetooth on this variant, and while the BMS is capable, the 4.4 rating with a 10% one-star share is worth factoring into your decision against a 4.7-rated pack at similar weight.
7. SUPER EMPOWER 12V 100Ah Group 24 Battery – Best Group 24 Drop-In
12V 100Ah LiFePO4 Battery, Group 24 Deep Cycle RV/Trolling…
100Ah at 12.8V
21.6 lb Group 24
6.49 x 10.24 x 8.98 inch case
100A BMS
5 year warranty
Pros
- True drop-in Group 24 fit with M8 terminals at 21.6 lb
- 100A BMS with cell balancing and temperature protection
- Low-temp charge cut-off below 32F with discharge cut-off at -4F
- Five year warranty with 24-hour support response
- Expands to 4S4P for 51.2V 400Ah
- Three supported charging options including LiFePO4
- MPPT solar and DC-DC
Cons
- No Bluetooth or app monitoring
- Existing lead-acid chargers are not suitable
- Energy storage only
- not for starting
Group 24 is the case size most small and mid-size boats actually have in their trays, and this one is a genuine drop-in at 6.49 by 10.24 by 8.98 inches with M8 terminals. If your existing tray is not Group 31, this is the pack that avoids the modification job.
The BMS is rated at 100A continuous with cell balancing and full electrical and temperature protection, which gives it far more headroom than the 50A packs in this roundup. That means it pairs sensibly with a 55-80lb motor, where a 50A management system would be the weak link.
Low-temperature charging cut-off is below 32F with discharge cut-off at -4F, and recovery happens above 41F. Capacity is 1280Wh, and it expands to 4S4P for 51.2V 400Ah or 20.48kWh if you ever need a bigger system built from the same chemistry.
Support is described as responding within 24 hours, and the five-year warranty is among the better ones here. Buyers who want app-based monitoring tend to look elsewhere, but for a fixed installation that is not a real loss.
Who the SUPER EMPOWER 12V 100Ah suits
Owners of boats with a Group 24 tray, which includes a lot of 16- to 18-foot multipurpose and pontoon boats. It is the pick when you want full Group 24 capacity, a 100A BMS and a five-year warranty without changing anything about your boat’s hardware.
It is also a sensible choice as a house or solar bank alongside a trolling setup, since the manufacturer lists LiFePO4 charger, MPPT solar and generator with DC-DC charging as supported paths.
What to check before you buy the SUPER EMPOWER
No Bluetooth, so you are relying on a voltmeter or your own monitoring. Given that generic shunt meters misread LiFePO4 chemistry, plan to judge state of charge by resting voltage instead.
Your existing lead-acid charger will not work with this. That applies to every lithium pack in this roundup, but it is worth saying plainly because it is the most common way people damage a new battery in the first month.
8. DC HOUSE 12V 100Ah Bluetooth Battery – Best Bluetooth Diagnostics
DC HOUSE 12V 100Ah Bluetooth LiFePO4 Trolling Motor Lithium…
100Ah at 12.8V
23.8 lb Group 24 footprint
Bluetooth 5.1
UL and UN38.3 cells
Low-temp cut-off at 19.4F
Pros
- Bluetooth 5.1 app reports per-cell voltage
- current and state of charge
- Push notifications for detected anomalies and a dedicated fault page
- Low-temp cut-off at 19.4F charging and -4F discharging with auto-recovery
- UL and UN38.3 certified cells with 15000 cycle claim
- Expands to 4 in series or 4 in parallel
Cons
- About 0.32 inch taller than a standard Group 24
- 3 year warranty
- Expansion limited to 8 batteries total
- Bluetooth range only about 5-10 meters
Most Bluetooth apps in this category show you a percentage and stop there. This one reports per-cell voltage and current, includes a dedicated fault display page, and sends push notifications when it detects an anomaly. For a battery bank that will sit unattended in a boat, that is the diagnostic depth you actually want.
The cells are UL and UN38.3 certified Class A LiFePO4 with a claimed 15000 cycle life, and UN38.3 is the transport certification that matters if your battery is ever shipped by air. The footprint is close to Group 24 at 6.6 by 10.2 by 9.2 inches.
Cold-weather thresholds are among the more conservative in this group: charging stops at 19.4F and discharging at -4F, with automatic recovery once the pack reaches 32F. In practice that means less winter downtime than packs that cut out at 32F with no auto-recovery.
Expansion is to four in series or four in parallel, up to eight batteries, which is one fewer configuration than the 4P4S designs elsewhere in this roundup. It is an energy-storage pack and is not designed for cranking.
Who the DC HOUSE 12V 100Ah suits
Anglers who want to know the health of a bank in detail rather than a single number, and people running a boat unattended for long periods. The fault page and notifications are genuinely useful if you run electronics overnight while the battery charges.
It is also a good fit for anyone who already has a Group 24 tray and wants Bluetooth without moving up to a larger case, provided your compartment has about a third of an inch of extra clearance.
What to check before you buy the DC HOUSE
The case is about 0.32 inch taller than a standard Group 24. In a tight battery box with a lid that already clears by a hair, that is the difference between fitting and not fitting, so measure with the lid closed.
The three-year warranty is the shortest among the five-year brands in this group, and Bluetooth range of roughly 5-10 meters means the phone has to be near the boat to connect. Expansion also stops at eight batteries rather than the sixteen a 4P4S layout allows.
9. Redodo 24V 50Ah Group 24 Battery – Best for 24V Setups
Redodo 24V 50Ah Group24 Trolling Motor LiFePO4 Battery
50Ah at 25.6V
21.1 lb
6.61 x 10.24 x 8.27 inch case
60A continuous
Bluetooth monitoring
Pros
- 21.1 lb for a complete 24V pack
- 60A continuous discharge for motors up to 100lb thrust
- Bluetooth app tracks charge
- cycle count
- temperature and health with remote power-off
- Grade A cells rated over 4000 cycles at full depth of discharge
- Five year warranty with 24 hour one-on-one support
- Expands to 10.24kWh
Cons
- 60A continuous is low for 100lb thrust in heavy conditions
- 4.3 average rating with a 10% one-star share
- Must be charged on arrival with a 0V-capable LiFePO4 charger
- Expansion limited to 4P2S
- Not for starting or golf cart use
Twenty-one pounds for a complete 24V system is the headline here. Instead of two 12V batteries, a bus bar and the balancing problems that come with series strings, this is one 25.6V pack with one pair of leads. For a mid-size boat with a 24V motor, that is a much cleaner installation.
The Bluetooth app tracks charge status, cycle count, temperature and overall health, and allows a remote power-off. Cycle count in particular is useful information over a multi-year ownership, because it tells you how hard the pack has actually been worked.
Capacity is 50Ah at 25.6V, roughly 1.28kWh, which is the energy of a single 12V 100Ah. Discharge is rated at 60A continuous and the manufacturer claims suitability for motors up to 100lb of thrust.
60A continuous feels modest for a 100lb motor working hard current, which helps explain a 4.3 average with a 10% one-star share. For a 70-80lb motor used normally, it is comfortable.
Who the Redodo 24V 50Ah suits
Owners of a 24V motor on a mid-size bass or multipurpose boat who want one battery instead of two. The single-pack approach removes parallel balancing concerns and halves the number of connections you have to make and keep sealed.
It is also a strong choice for anyone who prioritises weight above capacity. At 21.1 lb, this delivers 24V of system voltage in a package that most 12V packs cannot match, and the Bluetooth health data makes long-term ownership easier to manage.
What to check before you buy the Redodo
The 60A continuous rating is the honest limitation here. It is fine for a 70-80lb motor under normal use and tight for a 100lb motor in heavy current, so match the pack to the motor rather than to the boat length.
It must be charged on arrival with a LiFePO4 charger that has a 0V wake capability, or it will not come online at all. Expansion stops at 4P2S, which is a lower ceiling than the 4P4S packs in this roundup, and its 4.3 average sits below the other 24V option here.
10. VEMDIA 12V 100Ah Group 31 Battery – Best Entry-Level 100Ah
12V 100Ah LiFePO4 Lithium Battery Group 31 Deep Cycle for RV…
100Ah at 12.8V
24 lb Group 31
12.9 x 6.6 x 8.5 inch case
100A smart BMS
2 year warranty
Pros
- Most economical per amp-hour in this group
- Group 31 drop-in at 12.9 x 6.6 x 8.5 inches
- Claimed 15000+ cycles at 60% DOD and 6000 at 100% DOD
- Full charge in about 5 hours with a 14.6V 20A charger
- Discharge operation from -4F to 140F
- US-based support with 24-hour response
Cons
- 2 year warranty
- among the shortest here
- Highest internal resistance in the group at 120 milliohms
- No Bluetooth or app monitoring
- Screw terminals rather than common M8 posts
The case is 12.9 by 6.6 by 8.5 inches, which is a close Group 31 fit, and at 24 lb it is still roughly 70% lighter than the lead-acid it displaces. On a per-amp-hour basis it is the most economical pack in this roundup.
The cycle claims are aggressive on paper: 15000+ cycles at 60% depth of discharge, 8000 at 80% and 6000 at 100%, with a 10-year lifespan. The 100A smart BMS includes automatic low-temperature cut-off below 32F, and discharge operation is rated from -4F to 140F.
Charge time is the standout practical number. A full charge in about five hours with a 14.6V 20A LiFePO4 charger is roughly three times faster than an equivalent lead-acid bank would manage, which is a genuine advantage for a boat that gets used two or three times a week.
Expansion runs to 4S4P for 51.2V and 400Ah, and support is US-based with a 24-hour response guarantee. Those are good signals from a brand most buyers will not have heard of.
Who the VEMDIA 12V 100Ah suits
Budget-conscious anglers moving from a bank of lead-acid who want full 100Ah Group 31 capacity at the lowest cost in this roundup, and boaters who charge between trips and value fast turnaround more than app monitoring.
It suits anyone who wants to be able to say their battery will be full before the boat is launched. Five hours is a genuine change in how a week of fishing works, and no other pack in this list quotes that number as directly.
What to check before you buy the VEMDIA
The two-year warranty is the shortest of the twelve, and the 4.3 average with a 12% one-star share is the lowest satisfaction score in this group. If you keep a boat for a decade, a two-year warranty is a meaningful difference against a five-year pack.
Internal resistance is 120 milliohms, the highest in this group, which is why we would not pair it with a high-thrust motor. It also uses screw terminals rather than the M8 posts common on competing packs, so your existing hardware may not fit, and there is no Bluetooth monitoring.
11. HeyFuture 12V 100Ah Bluetooth Battery – Best Technical Build
HeyFuture 12V 100Ah Bluetooth LiFePO4 Battery for Rv…
100Ah at 12.8V
21.5 lb Group 24
JBD 100A smart BMS
4S4P to 48V 400Ah
5 year warranty
Pros
- Uses a reputable JBD 100A smart BMS with Bluetooth and cell balancing
- 21.5 lb Group 24 with molded cell frame and substantial welded busbars
- App allows remote charge and discharge cutoff showing real reserve
- Shock-resistant design suited to running rapids
- Expands to 4S or 4P for 48V 400Ah
Cons
- Cells are unbranded
- so true capacity is hard to verify
- No internal fuse
- external fusing required
- 4S2P layout limits per-cell fault detection
- Sealant-based waterproofing depends on factory quality
This is the pick for buyers who open the case. It uses a JBD 100A smart BMS, which is one of the more widely recognised management boards in the DIY and marine community, with Bluetooth and cell balancing built in. The internal construction uses a molded cell frame and substantial welded busbars rather than the spot-welded or tab-welded approach seen on some cheaper packs.
At 21.5 lb in a Group 24 footprint it is one of the lighter 100Ah options here, and the app lets you switch charging and discharging off remotely and see actual reserve rather than a guess. For a river boat running current, the shock-resistant design is a genuine consideration.
Technically inclined owners tend to rate this pack highly on internals, and reports of strong real capacity on small boats with light motors are common. Expansion goes to 4S or 4P for up to 48V 400Ah, and the warranty is five years with responsive after-sales support.
The critical reviews focus on details that matter if you care about them: unbranded cells, no internal fuse and sealant-based waterproofing whose quality depends on the factory. One report describes a cell failure within six months, so the warranty length is doing real work here.
Who the HeyFuture 12V 100Ah suits
Boat owners who know their electrical systems, run river current where shock resistance and build quality matter, and want a Group 24 pack with 100Ah of capacity and a reputable BMS without spending on a premium marine brand.
It is also a sensible choice for anyone with a 12V to 24V solar or backup system who wants to expand later, since the 4S4P capability reaches 48V 400Ah using the same model.
What to check before you buy the HeyFuture
There is no internal fuse, so you must fit external fusing on the positive lead. This is good practice on any battery, but with this pack it is not optional, and skipping it is how a short circuit becomes a serious event.
The cells are unbranded, which means real capacity and cycle life are difficult to verify independently, and the 4S2P layout limits how precisely the BMS can detect a single failing cell. The 125-review count is also the smallest in this roundup, so treat the consensus with appropriate caution.
12. XZNY Compact 24V 100Ah LiFePO4 Battery – Best Compact 24V
XZNY Compact 24V 100Ah LiFePO4 Battery for Trolling Motors…
100Ah at 25.6V
41 lb
13.59 x 7.48 x 9.65 inch case
100A continuous with 300A peak
UL certified IP67
Pros
- 30% smaller than a standard 24V 100Ah and 33% smaller than two 12V 100Ah units
- 100A continuous and 300A peak for 5 seconds with 2560W max output
- Single 24V pack removes parallel balancing concerns
- Integrated carry handles and hardware in two lengths included
- A-grade cells rated 5000 cycles and 10 year lifespan
- UL certified and IP67 rated
Cons
- 3 year warranty
- shorter than five-year competitors
- 41 lb makes it the second heaviest pack here
- Some units arrived without paperwork
- A few reports of units not holding charge after months
This is the one to look at if you want 24V capacity and your compartment is the problem. The case measures 13.59 by 7.48 by 9.65 inches, and the manufacturer claims it is 30% smaller than a standard 24V 100Ah and 33% smaller than pairing two 12V 100Ah batteries. On a boat where tray space is the limiting factor, that is the whole pitch.
Electrically it is well specified. The BMS delivers 100A continuous charge and discharge with 300A peak for five seconds and 2560W maximum output, which comfortably covers 24V motors in the 70-100lb range. Charging cut-off is 32F and discharge cut-off -8F, with high-temperature protection as well.
A-grade LiFePO4 cells are rated for 5000 cycles and a 10-year lifespan, and the pack is UL safety certified with an IP67 rating, which is a step up from the IP65 common elsewhere in this roundup. Carry handles are integrated and the hardware is included in two lengths.
Owners running trolling motors hard through a full week report holding charge without a single recharge, and several have measured 91-92% usable capacity in inverter cutoff testing, which is close to the theoretical figure for this chemistry.
Who the XZNY Compact 24V 100Ah suits
Boat owners who want 24V capacity and long runtime but have limited compartment space, particularly on smaller boats running 70-100lb motors. The UL certification and IP67 rating also make it the pick for anyone who wants a documented safety standard rather than a marketing claim.
It suits multi-day and full-week trips where 100Ah at 24V removes charging from the equation entirely, and support has replaced failed units including after a full year in service.
What to check before you buy the XZNY
At 41 lb it is the second heaviest pack in this roundup, and only the 36V unit is heavier. Check that your boat and your lifting situation are comfortable with that, particularly if you are loading from a trailer ramp.
The three-year warranty is shorter than the five-year competitors, and reliability reports are genuinely mixed, with several reviews describing a unit that stopped accepting a charge after a few months. Some units also arrive without paperwork, which suggests uneven packing. Expansion is limited to two in series and five in parallel, reaching 48V 500Ah.
How to Choose the Right Lithium Battery for Your Trolling Motor
Most disappointing lithium purchases trace back to one of six checks. Do them in order and you will not get this wrong, and you will also avoid the two problems that produce the most forum threads: motors cutting out and batteries that arrive unable to charge.
1. Match the voltage tier exactly
A 12V motor runs on a 12V system, a 24V motor on 24V, a 36V motor on 36V. There is no compensation for a mismatch. A 12V pack cannot drive a 24V motor to any useful speed, and a 36V pack on a 12V motor will damage the motor controller.
Within each tier, a 24V system is normally two 12V packs in series, and a 36V system is three. The single-pack alternatives in this roundup, the 24V Redodo and 36V OGRPHY, remove the series connections entirely.
2. Size amp-hours to realistic daily draw
Work out your average draw rather than your peak. A 55lb motor at half throttle draws far less than its headline number suggests, and lithium delivers nearly its full rated capacity, where lead-acid typically gives you about half. Most anglers running a 12V motor on a mid-size boat are well served by 50Ah, and 100Ah is the comfortable choice for full-day use or heavy current.
As a rough guide: 50Ah suits a kayak or small boat with a 30-50lb motor, 100Ah suits a 16- to 20-foot boat with a 55-80lb motor, and 24V 50Ah to 100Ah or a 36V 60Ah to 100Ah pack suits tournament and big-water rigs.
3. Check the BMS continuous rating against your thrust
This is the check most people skip and the one that decides whether your motor cuts out. A 50A BMS on a 100lb motor is a genuine mismatch, because the motor can pull far more than 50A on a hard acceleration. A 100A or 200A management system gives the headroom that hard pulls require.
Ask two questions: what is the continuous current, and what is the peak. The OGRPHY 36V pack rates 200A continuous and 1000A peak for three to five seconds, which is why it suits larger thrust. The 50A packs in this roundup are correctly matched to 30-50lb motors and nothing heavier.
4. Confirm the physical case fits your tray
Group 31 is 13 by 6.77 by 8.5 inches and is what most full-size boats use. Group 24 is smaller and fits many 16- to 18-foot boats. Several packs here, including the DC HOUSE, sit slightly taller than the nominal size, and the Timeusb and LiTime 50Ah units are not standard Group 31 at all. Measure the closed lid, not the empty opening.
Our general guide to trolling motor batteries for all-day fishing covers the physical fit question in more detail if you are working with an unusual tray.
5. Set a warranty floor of five years
The forum consensus is clear on this, and it is the standard we use. Five years is the minimum acceptable warranty, and anything shorter means you are buying the cells rather than the product. Eight of the twelve packs here carry five years or longer, with two at three years, one at two and one at a single year.
Length of warranty is also a decent proxy for confidence in the cells, because a manufacturer carrying a five-year commitment is accepting real long-term liability.
6. Decide whether Bluetooth is worth anything to you
Four packs here have meaningful Bluetooth monitoring: the LiTime 12V 100Ah, the LiTime 12V 50Ah, the DC HOUSE 12V 100Ah and the Redodo 24V 50Ah. The DC HOUSE is the most capable, with per-cell readings and fault alerts. The rest are conventional voltmeter setups, and you can add a shunt meter if you want numbers, though generic shunt meters misread LiFePO4 chemistry.
For anything beyond solar and RV storage, we have a fuller look at lithium batteries for RVs, which covers the larger-capacity configurations that overlap with big trolling setups.
Charging, Maintenance and Troubleshooting a Lithium Trolling Battery
Lithium is low-maintenance, not maintenance-free. The three recurring problems are charger mismatch, low-temperature shutdown and BMS lockout, and all three are manageable once you know what is happening.
Your charger must match both voltage and chemistry
A lead-acid charger pushes a different absorption profile and will over-charge LiFePO4 cells over time. Every manufacturer in this roundup specifies a lithium profile, generally 14.4-14.6V for a 12V pack, so use a charger with a LiFePO4 setting or a dedicated lithium charger. The BtrPower pack recommends 10A or less of charge current, and the VEMDIA fills from empty in about five hours on a 14.6V 20A charger.
Some packs also ship in a state where they must be woken before they will accept a charge. The OGRPHY includes a charger with a 0V wake function, and the Redodo and both LiTime packs specifically require a lithium-activation or MPPT charger on arrival. If a new battery will not charge, this is the first thing to check rather than a defect.
What to do when the motor stops
When a trolling motor cuts out under load, the battery has usually protected itself, not failed. Follow these steps in order. First, release the throttle and let the load drop to near zero, since a tripped BMS will often recover on its own once the current falls.
Second, measure resting voltage after a few minutes of quiet. A pack that reads well above its low-voltage cutoff and still will not power the motor points to a wiring or connector fault rather than the cells. Third, charge the battery fully with a lithium charger, then try again on a lower throttle setting.
Fourth, if it still trips, disconnect everything and let it rest, then reconnect. Finally, check whether a 12V motor is being fed by a 24V pack or a bank with too few cells, because both will trip a healthy BMS.
Persistent tripping with a correctly sized bank usually means the BMS current ceiling is below what the motor is asking for, which is a sizing problem rather than a battery problem. That is the argument for a 100A or 200A pack on a high-thrust motor.
Cold-weather charging and seasonal storage
Charging a LiFePO4 cell below freezing can plate lithium onto the anode permanently, which is why every serious pack here has a low-temperature charge cut-off. Thresholds in this roundup range from 19.4F on the DC HOUSE to 32F on the LiTime, Power Queen, SUPER EMPOWER and VEMDIA, and the Timeusb suspends charge below 0C and resumes at 5C. Discharge cut-offs are typically -4F to -8F.
Auto-recovery matters more than the threshold. A pack that resumes charging on its own once it warms up is a non-event; one that needs a charger with a wake function can leave you stuck on a cold morning. For off-season storage, keep the battery at a mid state of charge in a cool dry space and top it up monthly rather than leaving it full or empty.
Safety-wise, fit a fuse or breaker on the positive lead sized to the cable, use tinned copper marine wire with heat-shrink terminations, and avoid wire nuts entirely. Saltwater rigs deserve the same care as the battery itself, because corrosion on the connections causes the voltage drop that trips a BMS in the first place.
Frequently Asked Questions
Is a 100Ah lithium battery enough for a trolling motor?
Yes, for most situations. A single 12V 100Ah LiFePO4 pack comfortably runs a 55-80lb trolling motor on a 16- to 20-foot boat for a full day because lithium delivers nearly all of its rated capacity, where lead-acid typically gives you about half. For a 30-50lb motor on a small boat, 50Ah is usually enough. You need more than 100Ah, or a 24V or 36V system, for heavy current, very long days or tournament-level runtime.
How long will a 100Ah battery run a 55lb trolling motor?
On a typical day of fishing, running at partial throttle with intermittent bursts, a 12V 100Ah lithium pack will carry a 55lb motor for a full day. Because LiFePO4 holds a flat voltage curve and can be discharged to roughly 99% of rated capacity, the practical runtime is far longer than an equivalent lead-acid bank of the same amp-hour rating. Hard-throttle running in current is what shortens that.
How many batteries do I need to run a 36V trolling motor?
Traditionally you need three 12V batteries in series. A 36V LiFePO4 pack built as an 11-cell unit is a single-battery alternative that removes the series connections and the balancing concerns that come with them. A 36V 60Ah to 100Ah pack covers most anglers, and the 36V 100Ah unit in this roundup holds 3.84kWh with a 200A continuous BMS.
How many amp hours do I need for a 24V trolling motor?
For a 24V system, 50Ah at 25.6V is the practical starting point and 100Ah is the comfortable choice for full-day or heavy-current fishing. In energy terms, a 24V 50Ah pack holds about 1.28kWh, which is roughly equivalent to a 12V 100Ah. Match the pack’s continuous current to the motor: 60A suits motors up to about 80lb, and 100A or more suits 100lb motors.
Do lithium batteries damage trolling motors?
Not when the voltage tier matches. A healthy LiFePO4 pack paired with the correct motor is the normal, recommended setup, and the flat voltage curve keeps the motor at full speed longer than lead-acid does. The damage risk comes from mismatches: a 12V pack on a 24V motor, a bank with too few cells in series, or reversing polarity during installation. Never crank an outboard from a deep-cycle lithium pack.
How do I reset a lithium trolling battery that has shut down?
Release the throttle first, because a tripped BMS often recovers once current drops. Then measure resting voltage after a few minutes; a healthy reading rules out the cells and points to wiring or a connector. Charge the pack fully on a LiFePO4 charger and retry at a lower throttle setting. If it still trips, disconnect everything, let it rest and reconnect. A charger with a 0V wake function can revive a deeply discharged pack.
What is the 80/20 rule for lithium batteries, and do I need a special charger?
The 80% rule is a lead-acid guideline meaning you should not discharge a flooded or AGM battery below half its rated capacity in practice. LiFePO4 has no such restriction and can be discharged to roughly 99% of rated capacity, so the rule does not apply to lithium. You do need a lithium-compatible charger, set to about 14.4-14.6V for a 12V pack, because a standard lead-acid charger will over-charge the cells over time.
Bottom Line: Which Lithium Trolling Battery Should You Buy?
For most anglers reading this, the answer is the LiTime 12V 100Ah. It is the highest-rated pack we tested, it is the lightest full-size Group 31 option at 22.2 lb, its Bluetooth app is genuinely informative, and it carries a five-year warranty. It is the safest single recommendation we can make across a wide range of boats.
Match the pick to the boat instead. A kayak or small jon boat wants the LiTime 12V 50Ah at 11.3 lb. A cold-climate angler wants the Timeusb for its documented charge and discharge thresholds. A high-thrust motor wants the Power Queen for its surge protection, and a Group 24 tray points to the SUPER EMPOWER. A 24V motor gets the Redodo for weight or the XZNY for capacity in a small space.
Big water is where the OGRPHY 36V pack earns its place, since 3.84kWh and a 200A continuous BMS remove both the runtime and the motor-cutting-out problems in one purchase. Whatever you choose, buy the charger at the same time, size the BMS current above your motor’s thrust, and keep a separate starting battery for the outboard.
The best lithium batteries for trolling motors are the ones where the voltage tier, the continuous current rating and the case size all line up with the boat you actually own. Get those three right in 2026 and the rest is just a preference between apps and warranties.
