Choosing the right battery for a trolling motor shapes every minute on the water, from early morning bass runs to full-day excursions across open bays. Anglers juggling heavy lead-acid banks and constant recharges know how quickly a mediocre setup can ruin a trip, and that’s the gap lithium iron phosphate (LiFePO4) chemistry keeps filling. Below are ten purpose-built picks that pair sensible Group sizing with the deep-cycle stamina trolling setups demand.

OGRPHY 36V 105AH Lithium Golf Cart Battery
OGRPHY 36V 102AH Lithium Golf Cart Battery
What Each Pick Brings To The Table
The GrenerPower 12V 100Ah fits the standard Group 24 footprint that most kayak and small jon-boat trolling motors already expect, which makes the swap from a tired AGM (Absorbent Glass Mat) unit a clean drop-in. Its LiFePO4 chemistry (lithium iron phosphate, prized for thermal stability and long cycle life) weighs roughly a third of a comparable lead-acid pack, so trimming weight forward of the transom is a real advantage for solo anglers.
The integrated 100A BMS (Battery Management System, an internal circuit board that protects against overcharge, over-discharge, and shorts) watches cell balance continuously, which matters when you push a 12V trolling motor across a long Saturday on the water. Compared with the Power Queen Group 24 pair coming up later, this single-pack format suits folks who want a simpler one-battery setup rather than a 24V series arrangement.
Strong Points
- Group 24 case drops into common marine trays without modification
- Cylindrical Grade A cells support a deep-cycle claim well above lead-acid baselines
- Lightweight build (roughly 30% of an equivalent AGM) eases portage and balance
- 100A BMS provides multi-layer electrical protection for everyday use
Things To Consider
- Single 12V unit means a 24V trolling motor still requires two batteries wired in series
- No bundled charger, so a compatible lithium charger must be sourced separately
Key Specs
Right Fit For
Anglers running a single 12V trolling motor on a kayak or small jon boat who want a lighter, longer-lasting drop-in replacement for an AGM battery.
Where Another Pick Suits Better
For a 24V trolling motor that needs a single-box solution instead of two in series, the VATRER POWER 24V 300Ah unit offers a cleaner one-piece answer.
SOK takes a different approach to the Group 24 format with a translucent case that lets you eyeball the cells and connections without cracking anything open. That alone is a meaningful maintenance perk for owners who like to spot corrosion early or verify their BMS indicator lights at a glance. The IP65 rating (a standard that protects against dust ingress and low-pressure water jets from any direction) also gives the casing genuine splash-and-rain confidence.
This battery sits in the same 12V 100Ah category as the GrenerPower unit above, so the question comes down to build philosophy. Where GrenerPower leans toward a conventional sealed look, SOK leans into visibility and easier diagnostics. For anglers in wetter climates or anyone storing gear in a damp boathouse, that sealed-but-see-through construction can pay off over seasons of use.
Standout Benefits
- Translucent shell allows visual inspection of cells and internal layout
- IP65 sealing offers solid dust and splash resistance for marine environments
- BCI Group 24 (Battery Council International standardized case dimensions) sizing matches common trolling motor trays
Worth Noting
- Translucent plastic can show UV yellowing over long sun exposure compared to opaque housings
- Still a single 12V unit, so 24V systems need two wired in series
Key Specs
Made For
Boat owners who appreciate visual diagnostics and want a sealed, splash-resistant 12V pack for a typical trolling motor setup.
Look Elsewhere When
Heads-up anglers chasing maximum runtime per charge should consider the VATRER POWER 24V 300Ah battery instead for a much larger capacity bank.
Stepping up to a 24V trolling motor changes the battery math considerably, and the VATRER POWER 24V 300Ah LiFePO4 unit answers that with a single-box solution rather than two 12V batteries wired in series (positive of one connected to negative of the other to double the voltage). The 300Ah capacity gives serious leg room for anglers who spend entire days at varied speeds, and the integrated app monitoring turns state-of-charge data into something you can check from a phone rather than guessing.
The 200A BMS is rated for higher continuous loads than the 12V Group 24 options earlier in this list, which matters when a 24V motor is asked to push a heavier boat through current or chop. Compared with the OGRPHY 36V units further down, this 24V platform stays simpler for owners who haven’t moved up to a 36V trolling system yet but still want more capacity than two mid-size batteries can deliver.
Notable Upsides
- Single 24V 300Ah pack replaces a pair of 12V batteries wired in series
- App monitoring offers remote visibility into voltage, current, and state of charge
- 200A continuous BMS handles sustained draw from larger trolling motors
- Built-in high and low temperature cutoff for added safety
Trade Offs
- Heavier and bulkier than 12V options, which can challenge smaller craft
- 24V system requires a compatible charger, adding to total cost
Feature Snapshot
Best Suited To
Owners running 24V trolling motors who want a single high-capacity lithium bank with app-based monitoring rather than juggling two 12V units.
Skip It When
Boaters on a 36V trolling system will find the OGRPHY 36V 150AH battery a more directly matched voltage platform.
Standard lithium batteries can struggle to charge when temperatures plunge, and the VATRER POWER 12.8V 300Ah addresses that with a self-heating function that warms the cells before accepting a charge. For ice anglers and cold-climate boaters, that built-in heater turns a battery that would otherwise refuse to top up into one that comes back to full strength between runs.
The 12.8V 300Ah capacity lands this battery in the same class as a pair of the GrenerPower 100Ah units combined, though it sits in a single box. The app monitoring feature carries over from the 24V sibling, letting you track state of charge from inside a shanty. Compared with the VATRER 24V model above, this one trades raw voltage for cold-weather charging flexibility.
The Good Stuff
- Self-heating function allows safe charging in sub-freezing conditions
- 12.8V 300Ah capacity delivers extended runtime in a single box
- App monitoring adds visibility into voltage and remaining capacity
Honest Caveats
- Larger physical footprint than a standard Group 24 battery, so tray sizing matters
- Self-heating draws extra power during cold-weather charging sessions
Who Should Grab It
Cold-climate and ice-fishing anglers who need a high-capacity 12V battery that will charge reliably when temperatures drop below freezing.
A Better Fit Elsewhere
For warm-weather 24V setups where cold-weather heating is unnecessary, the VATRER POWER 24V 300Ah unit offers a simpler match.
The OGRPHY 36V 100AH battery targets owners who run high-thrust trolling motors on larger boats, where voltage demands climb beyond the 24V class. The included 25A LiFePO4 charger saves the guesswork of sourcing a compatible unit, which is a meaningful plus for anyone stepping into lithium for the first time. The 200A BMS supports a continuous output that larger trolling motors can lean on during sustained pushes against wind or current.
At 38.4V nominal and 100Ah, this entry sits at the modest end of OGRPHY’s 36V line, giving you a manageable capacity point for owners who want a 36V platform without the weight of the larger packs below. Compared with the Power Queen 12V units earlier, this battery consolidates three 12V batteries’ worth of voltage into a single enclosure, simplifying wiring at the cost of bulk.
A Favorable Mix
- Single-box 36V format replaces three 12V batteries in series
- 200A BMS supports high continuous draw for large trolling motors
- Bundled 25A LiFePO4 charger removes a common compatibility hurdle
- Grade A LiFePO4 cells target long cycle life under deep discharge
Possible Compromises
- Heavier than a single 12V battery and harder to position in small hulls
- 36V platform requires matching motor and wiring, so retrofitting adds effort
Built With In Mind
Large bass boat owners running 36V trolling motors who want a single-battery lithium swap with a compatible charger included.
Swap It Out When
Kayak or jon boat anglers on a 12V system should look at the GrenerPower 12V 100Ah Group 24 unit for a more appropriately sized battery.
Stepping up the OGRPHY line, the 36V 150AH unit adds a touch LCD monitor and mobile app pairing that turn the battery into something closer to a managed power hub. The 200A BMS with 1000A peak current handles the brief surges a 36V trolling motor pulls when accelerating, and the higher 150Ah capacity extends runtime well beyond the 100AH sibling above. For tech-forward boaters who like checking state of charge from the helm, the integrated display adds real convenience.
This battery shares the 36V platform with the OGRPHY 100AH unit earlier, so the choice comes down to capacity needs and how much you value the monitoring hardware. The added capacity does add weight and footprint, so smaller hulls may struggle to accommodate it. Where the 100AH unit is a comfortable middle ground, this one targets owners who push longer days or bigger waters.
Well-Handled Touches
- Touch LCD monitor offers at-a-glance voltage and capacity readings
- Mobile app extends visibility to a phone or tablet on the boat
- 200A continuous BMS with 1000A peak headroom for surge loads
- 150Ah capacity delivers longer runtime than the 100AH sibling
Worth Bearing In Mind
- Heavier than the 100AH version, which can tax smaller transom setups
- Premium feature set comes at a higher entry cost than the base OGRPHY 36V model
Whose Shelf It Belongs On
Boat owners on 36V trolling systems who want the longest runtime in the OGRPHY line and appreciate integrated monitoring hardware.
Consider Something Else When
Budget-focused shoppers who mainly need a 36V platform without app and display extras should consider the OGRPHY 36V 100AH battery instead.
Power Queen bundles two 12V 100Ah Group 24 LiFePO4 batteries together, which directly addresses 24V trolling motor setups that would otherwise require buying two batteries separately. Each unit uses the same Group 24 footprint as the GrenerPower unit earlier, so a pair wired in series fits the same trays you’d use for a single 12V battery. The drop-in format means no rewiring of trays or brackets for the upgrade.
The pair format makes sense for owners who want a clean 24V bank without committing to a single 24V battery box. Compared with the VATRER 24V 300Ah option above, this pair delivers 200Ah total capacity at a more modest price point, though it requires series wiring at install. The split format also lets you replace batteries individually over time, which is a real-world ownership perk.
Everyday Wins
- Two-battery bundle simplifies 24V trolling motor upgrades
- Group 24 case fits standard marine battery trays in each unit
- Individual battery replacement is possible without replacing the whole bank
- Lightweight LiFePO4 cells reduce overall weight versus lead-acid equivalents
Small Caveats
- Series wiring between batteries is required for 24V operation
- Pair format means twice the mounting space compared to a single 24V pack
Feature Snapshot
Who Will Love This
24V trolling motor owners who prefer a two-battery series configuration over a single larger 24V pack, especially those who want flexibility for future replacements.
Another Choice May Suit
For a simpler single-box 24V installation with app monitoring, the VATRER POWER 24V 300Ah battery offers a more consolidated solution.
The Power Queen Group 31 variant lands in a tighter footprint than the Group 24 units earlier, which matters in boat battery compartments with limited clearance. Group 31 sizing (a slightly larger BCI footprint than Group 24) tends to fit compact trolling motor trays while still accommodating 100Ah of usable capacity. For owners whose tray was designed around an older Group 31 AGM, this lithium swap keeps the original layout intact.
This battery shares Power Queen’s broader LiFePO4 platform with the 2PACK Group 24 entry above, so build quality and BMS design are consistent across the line. Where it stands apart is the format flexibility: the Group 31 case slots into spaces a Group 24 simply won’t, which can make it the only practical option for certain hulls. The 100A BMS and deep-cycle rating support multi-hour trolling sessions comfortably.
Positive Takeaways
- Group 31 footprint fits battery trays too tight for Group 24 units
- 100A BMS handles sustained trolling motor draws
- Supports series and parallel configurations for expanded systems (4P4S capability)
Points To Note
- Group 31 size is slightly larger than Group 24, so double-check tray clearance
- Charger is sold separately, adding to total install cost
Perfect Match For
Boat owners with Group 31 battery trays who want a clean lithium swap that keeps the existing compartment layout unchanged.
Reach For A Different Pick When
Anglers working with confirmed Group 24 trays will find the GrenerPower 12V 100Ah Group 24 a better-fitting drop-in.
The OGRPHY 36V 105AH battery arrives as a complete kit with a 25A charger, touch LCD monitor, and 200A BMS, which removes most of the compatibility guesswork for first-time lithium upgraders. The 105Ah capacity lands in a practical middle zone, delivering meaningful runtime without the weight jump of the 150AH sibling. For boat owners transitioning off lead-acid, this all-in-one package simplifies the install considerably.
The 1000A peak current rating (sustained for short bursts) supports the surge demands larger trolling motors put on the battery during acceleration. Compared with the OGRPHY 150AH unit earlier, this version trades some capacity for a more approachable price point, while still offering the touch monitor and BMS protection that define the line. It’s a solid entry point into 36V lithium ownership.
Everyday Perks
- Complete kit includes a matched 25A charger for immediate setup
- Touch LCD monitor displays voltage and capacity without needing an app
- 200A BMS with 1000A peak handles trolling motor surge demands
- 105Ah capacity balances runtime and weight for medium-sized boats
A Few Limitations
- Lower capacity than the 150AH OGRPHY option for extended-runtime needs
- 36V platform still requires a matched trolling motor for direct use
Best Suited To
First-time lithium upgraders running 36V trolling motors who want a complete package with a charger and monitor included.
Where A Sibling Pick Shines
Anglers who prioritize maximum runtime from the same platform should step up to the OGRPHY 36V 150AH battery instead.
The OGRPHY 36V 102AH unit adds a built-in 12V DC interface that powers accessories like lights and horns directly from the battery, eliminating the need for a separate 36V-to-12V converter (a device that steps voltage down to run standard 12V electronics). For boats with running lights, bilge pumps, or fish-finder setups, that integrated port simplifies wiring noticeably. The touch LCD monitor and 25A charger carry over from the sibling 105AH unit above.
The 102Ah capacity sits just slightly below the 105AH entry, so the difference between the two is more about the accessory port than the core power. Owners with even modest 12V accessory loads will appreciate the convenience, though there’s a practical ownership note: the 12V port needs to be switched off via the monitor or app after use to avoid parasitic drain (slow power loss from electronics that remain connected when the boat is idle). Compared with the higher-tier 150AH unit, this one targets boaters who value accessory integration over maximum runtime.
Noteworthy Benefits
- Integrated 12V DC port powers lights and accessories without a converter
- Touch LCD monitor and 25A charger included for straightforward setup
- 200A BMS with 1000A peak current supports trolling motor surges
Points To Keep In Mind
- 12V accessory port must be switched off after use to avoid parasitic drain
- Capacity is slightly lower than the 105AH sibling for marginal runtime loss

Built With In Mind
Boat owners running 36V trolling motors who also want to power 12V accessories like lights or horns from the same battery, simplifying onboard wiring.
Where A Sibling Pick Shines
For pure runtime without the accessory port, the OGRPHY 36V 105AH battery delivers a slightly higher capacity at a comparable feature level.
Picking The Right Battery For Your Trolling Setup
Voltage matching comes first. Most smaller trolling motors run on 12V, mid-size setups use 24V, and larger boats with high-thrust motors typically require 36V. Picking a battery with the wrong nominal voltage means rewiring or adapting the motor connection, so confirm your motor’s spec before choosing between the 12V, 24V, and 36V picks above.
Capacity (measured in amp-hours, or Ah) determines runtime. A 100Ah battery can theoretically deliver 5 amps for 20 hours, but trolling motors vary their draw based on speed, current, and weeds. For full-day outings, 100Ah is the practical floor; 200Ah or more gives real headroom. Pairing two 12V batteries in series gives you higher voltage but not double the runtime, because amp-hours stay the same.
Group size matters for fit. Group 24, Group 27, and Group 31 are BCI standardized case dimensions, and your boat’s battery tray dictates which one drops in without modifications. Measure your existing tray before ordering, especially if you’re swapping from a smaller AGM to a larger lithium box.
Cold-weather charging deserves attention if you fish shoulder seasons. Standard LiFePO4 cells can be damaged by charging below freezing, so the self-heating VATRER POWER 12.8V 300Ah unit is worth considering for ice anglers and early-spring boaters.
Monitor features add real convenience. Touch displays and app-connected BMS modules let you check state of charge from your phone or at a glance, which removes the guesswork that comes with voltage-only readings on older batteries.
Key Considerations Across These Picks
Wrong Turns To Avoid
A common slip-up is buying a 12V battery for a 24V trolling motor and expecting the motor to adapt, but motors are designed for specific voltage inputs and won’t perform correctly on the wrong supply. Always confirm your motor’s voltage requirement before choosing between the 12V, 24V, and 36V options in this list.
Another trap is ignoring Group size until install day. A Group 31 battery simply won’t seat in a Group 24 tray, and forcing the fit can crack the case or pinch cables. Measure your compartment before ordering so the lithium swap lines up with your existing layout.
Where The Extra Money Goes
Higher-capacity batteries cost more because of the additional LiFePO4 cells inside, and that extra capacity translates directly into longer runtime between charges. For anglers who spend full days on the water, that headroom justifies the price difference over entry-level 100Ah options.
Premium picks also add monitoring hardware, like touch screens and app connectivity, that simpler batteries lack. These features don’t extend runtime, but they do remove uncertainty about remaining capacity, which can be a real confidence boost on multi-day trips or when running electronics alongside the trolling motor.
Frequently Asked Questions
How long does a 100Ah lithium battery last on a trolling motor?
Runtime depends on your motor’s amp draw at the speed you typically use. At a moderate 20-amp draw, a 100Ah battery delivers roughly five hours of operation before reaching a low state of charge, though heavy current or wind cuts that time substantially.
Can I replace my lead-acid trolling battery with lithium directly?
In most cases yes, as long as the lithium battery’s voltage matches your motor’s requirement and the Group size fits your tray. You will likely need a lithium-compatible charger, since lead-acid chargers can damage LiFePO4 cells over time.
Is a self-heating battery necessary for cold-weather fishing?
Standard LiFePO4 batteries should not be charged below freezing, so a self-heating unit like the VATRER POWER 12.8V 300Ah makes sense for ice anglers or anyone fishing through late-fall and early-spring temperatures.
What is a BMS and why does it matter?
A Battery Management System is an internal circuit board that protects the cells from overcharging, over-discharging, short circuits, and excessive current draw. A higher-amp BMS (like the 200A units in the OGRPHY line) supports more demanding trolling motors without tripping protection.
Should I buy one 24V battery or two 12V batteries in series?
Both approaches work, but a single 24V battery simplifies wiring and reduces connection points. Two 12V batteries in series cost less and let you replace one unit at a time, which is a real-world ownership perk for long-term use.
The Takeaway
Trolling motor batteries come down to matching voltage to your motor, capacity to your typical day on the water, and Group size to your tray. The picks above cover the common combinations, from kayak-friendly 12V drop-ins to high-capacity 36V banks for larger boats. Take a moment to confirm your motor voltage and tray dimensions, and the right battery from this list should drop in without surprises.
