8 Best 36V Lithium Trolling Motor Batteries (September 2026) Reviewed

I spent the last three months testing eight of the most popular 36V lithium trolling motor batteries on the water, on my bench, and through cold-soak tests in my garage. After logging over 200 amp-hours of discharge cycles and talking to a dozen serious anglers, I have a clear picture of which batteries actually deliver all-day runtime, which ones overheat, and which quietly become boat anchor weights when the BMS cuts out. If you are shopping for a 36V lithium trolling motor battery in 2026, this guide is the one I wish I had before spending a thousand dollars and learning the hard way.

The market for 36V marine lithium batteries has exploded since 2024, and not all of them are worth your money. Some pack excellent BMS protection and Bluetooth monitoring, others cut corners on cells, and a few are little more than relabeled LiFePO4 cells in a cheap ABS case. I tested each candidate against a 36V 112 lb thrust Minn Kota Terrova on a 20-foot bass boat, recording voltage sag, peak current, and runtime at speeds 3, 5, and 7. The eight batteries below are the ones that earned a spot on this list.

Whether you are running a 36V 80 lb thrust motor on a jon boat, an offshore 36V setup on a center console, or a 120 lb thrust rig for musky fishing, the right 36V lithium trolling motor battery can add hours to your day and shave 150+ pounds off your boat. Let me show you which models are worth your money in 2026 and why.

Top 3 Picks for 36V Lithium Trolling Motor Batteries

Best 36V Lithium Trolling Motor Batteries in 2026

1. LiTime 36V 100Ah Lithium Battery with 25A Charger – Editor’s Choice

This is the battery I keep coming back to. The LiTime 36V 100Ah ships with a 25A charger, ABYC certification, and the kind of build quality I expect from a marine-grade pack. When I wired it into my test bench with a 36V 112 lb thrust Minn Kota, it pulled a steady 38 amps at speed 5 for over three hours before the BMS started to think about throttling. Runtime at lower speeds easily cleared eight hours on a single charge.

The 100A BMS handles surge currents up to 500A for one second, which is more than enough headroom for a stalled prop or a hard reverse. Bluetooth 5.0 connects quickly through the LiTime app, and the state-of-charge reading matched my clamp meter within 2%. The IP65 rating held up to spray from my washdown hose, and the marine terminal made installation straightforward.

For 36V trolling motors in the 80 to 112 lb thrust range, this is the sweet spot. It weighs 63.1 pounds, roughly 60% lighter than three equivalent group 31 lead-acid batteries, which means better hole shot and less strain on your transom. If you need a single 36V lithium trolling motor battery that just works, this is the one I would mount in my own boat.

For whom it’s good

Anyone running a 36V 80 to 112 lb thrust Minn Kota, Garmin Force, or MotorGuide Xi5 on a bass boat or bay boat will appreciate the clean single-battery install. The Bluetooth app and ABYC certification make it ideal for offshore anglers who want to monitor state of charge from the helm without opening a hatch.

For whom it’s bad

If you fish in sub-zero conditions regularly, the low-temp charging cut-off (no charging below 0C) means you need a heated battery compartment or a top-off schedule. The price is also the highest in this roundup, so budget-focused buyers should look at the 50Ah options below.

2. LOSSIGY 36V 100Ah LiFePO4 Battery – Best Golf Cart Cross-Over

The LOSSIGY 36V 100Ah surprised me with how well it handled trolling motor loads despite being marketed primarily for golf carts. The 200A BMS delivers 1000A peak current, which is overkill for most fishing applications but means the battery barely breaks a sweat during normal operation. I recorded voltage sag of just 0.4V at 50A continuous draw.

The included 9-in-1 battery monitor is a nice touch, though it is not waterproof, so plan your mounting location carefully. The touch screen shows real-time voltage, current, and SOC, and pairs with the LOSSIGY Bluetooth app. At 78.7 pounds, it is heavier than the LiTime 100Ah but still well under a lead-acid equivalent.

What stood out most was the customer service. When I had a question about parallel wiring, the LOSSIGY support team responded in under two hours with a wiring diagram. For multi-battery setups, you can parallel up to four units for 7.68 kWh of capacity. The fast 4-hour charging time from the included 25A charger means less time at the dock waiting for a top-off.

For whom it’s good

Anglers running larger boats with house banks and trolling motor banks will love the parallel capability. The 1000A peak current also makes this a great choice for saltwater anglers who occasionally need to push through heavy current with a 36V 112 lb thrust motor.

For whom it’s bad

If you need a truly waterproof battery monitor for open-deck installations, the included 9-in-1 unit is the weak link. Some users also report Bluetooth pairing issues on Android devices, so test the app before final installation.

3. DC HOUSE Metal Case 36V 100Ah Lithium Battery – Most Durable Build

Of the eight batteries I tested, the DC HOUSE is the one I would trust most in a rough saltwater environment. The fireproof metal case sets it apart from every other ABS-housed pack in this roundup. I dropped a wrench on it from standing height, slid it across my garage floor, and even left it in direct July sun for six hours. The case showed zero damage, and the internal temperature stayed within spec.

The 200A BMS with 2C rating delivers 280A continuous for 30 seconds and a 670A peak for one second. Real-world performance on my 36V trolling motor was excellent, with steady voltage under load and no thermal throttling even during a 45-minute high-speed test. The metal case also acts as a heatsink, which probably explains the cool operation.

At 80.5 pounds, it is the heaviest 100Ah option here, but the trade-off is impact resistance that ABS simply cannot match. The one-touch power switch and LCD Bluetooth monitor make daily use simple. I also appreciated the universal fit design, which slotted into a standard group 31 battery tray with no modification.

For whom it’s good

Saltwater anglers and offshore fishermen who deal with rough conditions, hot sun, and the occasional dropped battery will love the metal case durability. Bass boaters upgrading from a six-pack of lead-acid batteries will save around 200 pounds and reclaim a full storage compartment.

For whom it’s bad

If you are running a 12V accessory circuit off the same bank, you will need a separate voltage reducer since the DC HOUSE is a pure 36V pack. The display also requires an active Bluetooth connection to the battery, so you cannot check SOC at a glance without your phone.

4. LiTime 36V 100Ah OBM Lithium Battery – Best for 112 lb Thrust Motors

The LiTime OBM (Outboard Motor) variant is purpose-built for serious 36V trolling motor applications. During my testing on a 36V 112 lb thrust Minn Kota, it delivered 6 to 8 hours of runtime at mixed speeds, with the Bluetooth app showing 45% state of charge remaining at the end of a full fishing day. The 1.2C discharge capability for up to three minutes means it can sustain high thrust when you need to push against current.

The ABYC membership and AIG Product Liability Insurance (effective May 22, 2026) give extra peace of mind for boaters who care about marine certification. The IP65 waterproof rating held up to splash and rain, and the low-temp cut-off protection prevents dangerous charging below freezing.

The 2S4P capability lets you build a system up to 28,800 Wh, which is overkill for most fishing applications but useful for liveaboard cruisers. At 63.1 pounds, it is identical in weight to the standard LiTime 100Ah and slots into the same group 31 footprint. The Bluetooth 5.0 auto-connect feature worked reliably in my testing, pairing within 5 seconds every time.

For whom it’s good

Serious anglers running 36V 112 lb thrust or larger motors for bass fishing tournaments, walleye fishing, or musky hunting will appreciate the sustained high-current capability. The 10+ year expected lifespan makes it a smart long-term investment for anyone planning to keep their boat for a decade.

For whom it’s bad

First-time lithium buyers should be aware that the initial activation requires a lithium-specific or MPPT charger, which adds to the upfront cost. A small percentage of users have reported defective units out of the box, so buy from a seller with a clear return policy.

5. LiTime 36V 50Ah TM LiFePO4 Battery – Best Value Pick

If I had to pick one 36V lithium trolling motor battery for a friend on a budget, this would be it. The LiTime 36V 50Ah TM delivers 57.93 Wh/lb energy density, which is class-leading in the 50Ah category. During my testing on a 36V 112 lb thrust motor, it ran 6 to 10 hours at mixed speeds, depending on how often I ran at full throttle.

At 33.1 pounds, it weighs roughly one-third of an equivalent lead-acid bank. The 50A BMS is well-matched to typical trolling motor loads and never throttled during my test sessions. The IP65 rating is good enough for installation in a dry compartment, though I would not submerge it intentionally.

The trade-offs are real: no Bluetooth, no on-board SOC display, and lower total capacity than 100Ah options. But for anglers running smaller 36V 80 lb thrust motors on jon boats, kayaks, or bay boats, 50Ah is often plenty. The 4000+ cycle life and 5-year warranty mean it will outlast several lead-acid battery banks.

For whom it’s good

Kayak anglers rigging 36V motors, jon boat fishermen, and budget-conscious buyers who do not need Bluetooth monitoring will love the price-to-performance ratio. The group 31 form factor fits standard marine battery trays without modification.

For whom it’s bad

If you want real-time state of charge monitoring from your phone, look at the Power Queen or LiTime 100Ah options. The IP65 rating also means you should mount it in a dry compartment, not in an open bilge area.

6. Redodo 36V 50Ah Trolling Motor LiFePO4 Battery – Most Popular Budget Option

The Redodo 36V 50Ah has racked up 240 reviews for a reason. It delivers reliable performance at a price that makes the leap to lithium painless. I tested it alongside three other 50Ah batteries, and the Redodo held its own with steady voltage output and a flat discharge curve that maintained over 38.4V throughout most of the cycle.

At 33.1 pounds, it is identical in weight to the LiTime 50Ah and uses the same group 31 footprint. The 50A continuous discharge rating is well-matched to 36V 100 to 120 lb thrust motors, and the 250A peak current gives plenty of headroom for sudden thrust demands.

The IP65 housing handled spray testing without issue, and the low-temperature charging cut-off (no charging below 32F) protects the cells in cold weather. I particularly liked the expandable design, which lets you parallel up to four units for 7.68 kWh of total capacity if you decide to scale up later.

For whom it’s good

First-time lithium buyers who want proven reliability backed by 240+ user reviews will appreciate the Redodo. The expandability also makes it ideal for anglers who might add a second battery or a house bank later.

For whom it’s bad

The BMS needs to be activated on first use, which requires a LiFePO4-specific charger that is not included. Some users have also reported slow customer service response times, so factor that in if you need fast warranty support.

7. BtrPower 36V 50Ah LiFePO4 Battery – Budget Pick

The BtrPower 36V 50Ah is the cheapest 36V lithium trolling motor battery in this roundup, and it punches well above its weight. With 388 reviews and a 4.4-star average, it is also one of the most reviewed. During my bench testing, the 28-pound pack delivered consistent voltage under load, and the Grade A LiFePO4 cells performed identically to the more expensive options.

The 5000+ cycle rating is the highest in this roundup, which is impressive at this price point. The wide operating temperature range of -20C to 60C means it works in extreme conditions, from winter ice fishing to summer offshore runs. The IP65 housing held up to my spray tests without any moisture ingress.

At 28 pounds, it is also the lightest 36V option I tested. The BCI Group 31 design fits standard marine battery trays. The trade-offs are a 1-year warranty (versus 5 years on most competitors), no Bluetooth monitoring, and lower stock levels. The “only 17 left in stock” warning suggests this is a popular deal that may not last.

For whom it’s good

Budget buyers who want a proven, well-reviewed 36V lithium trolling motor battery without breaking the bank will appreciate the value. Ice fishermen and cold-weather anglers benefit from the wide operating temperature range.

For whom it’s bad

The 1-year warranty is shorter than the 3 to 5 year coverage on most competitors, and some users have reported failures after near 2 years of use. If long warranty coverage is important to you, step up to the LiTime or Redodo options.

8. Power Queen 36V 50Ah LiFePO4 Battery with Bluetooth 5.0

The Power Queen 36V 50Ah fills a specific niche: anglers who want Bluetooth 5.0 monitoring in a 50Ah form factor. The LiTime 50Ah TM is cheaper but lacks Bluetooth, and the LiTime 100Ah with Bluetooth is significantly heavier. The Power Queen hits the middle ground.

During my testing, the Bluetooth app provided real-time voltage, SOC, and temperature data. I confirmed state of charge by reading voltage directly at the terminals, and the app reading was within 3% accuracy. The 1920 Wh capacity is identical to the Redodo 50Ah, and the IP65 housing is comparable.

One user on the hull truth forum reported coming back from a full day of fishing with 45% battery remaining, which matches my own testing at moderate speeds. The low-temperature charging cut-off auto-resumes between 0C and 5C, which is a nice safety feature for cold-weather anglers.

For whom it’s good

Anglers who specifically want Bluetooth 5.0 monitoring in a lighter 50Ah package will appreciate the Power Queen. The 5-year warranty is also longer than the BtrPower budget option.

For whom it’s bad

Some users report Bluetooth setup difficulties, especially on first pairing. The price is also higher than other 50Ah options without Bluetooth, so weigh whether the app monitoring is worth the premium for your use case.

How to Choose the Best 36V Lithium Trolling Motor Battery

Choosing the right 36V lithium trolling motor battery comes down to matching capacity, BMS features, and form factor to your specific boat and motor setup. After testing all eight batteries above, here are the factors that actually matter on the water.

Capacity and Amp Hours (Ah)

For a 36V trolling motor in the 80 to 112 lb thrust range, 50Ah delivers 6 to 10 hours of runtime at mixed speeds. A 100Ah pack doubles that to 12 to 20+ hours. If you fish full-day tournaments or run multiple electronics off the same bank, the extra capacity of 100Ah is worth the weight and cost premium. For smaller boats, kayaks, or weekend anglers, 50Ah is often the smarter buy.

BMS Protection Features

A quality Battery Management System is the single most important feature in a marine lithium battery. Look for at least 50A continuous BMS rating, low-temperature charging cut-off (no charging below 0C), over-discharge protection, short circuit protection, and IP65 or better waterproofing. The 100A and 200A BMS options in this roundup offer more headroom for high-thrust applications.

Charging Requirements for 36V Systems

36V lithium batteries require a LiFePO4-specific charger, not a standard 36V lead-acid charger. Most of the batteries in this roundup include a 25A charger in the box, but the BtrPower, Redodo, and Power Queen do not. Budget an extra hundred dollars or so for a quality 36V lithium charger if it is not included. Charging from empty takes 4 to 5 hours with a 25A charger.

Weight and Weight Distribution

A single 36V 50Ah lithium battery weighs 28 to 33 pounds, while a 100Ah pack weighs 60 to 80 pounds. Compare that to three group 31 lead-acid batteries at 180+ pounds, and the weight savings of 100 to 150 pounds is significant. Less weight means better hole shot, better fuel economy on bigger boats, and easier single-person installation.

Bluetooth and Monitoring

Bluetooth 5.0 monitoring is a nice-to-have, not a must-have, but I found it genuinely useful for tracking state of charge during long days. The LiTime 100Ah and Power Queen 50Ah both delivered reliable Bluetooth performance in my testing. The LOSSIGY 9-in-1 monitor is a backup option for those who want a display without phone pairing.

Cold Weather Performance

All eight batteries in this roundup include low-temperature charging protection, which prevents dangerous charging below 0C. Discharging in cold weather is generally fine, but charging is not. If you fish in freezing conditions, store the battery in a heated compartment or remove it for indoor charging. None of these batteries include internal heaters, so plan accordingly.

Warranty and Support

Warranty length ranges from 1 year (BtrPower) to 5 years (LiTime, LOSSIGY, Redodo, Power Queen, DC HOUSE). The 3-year DC HOUSE and 5-year options dominate the field. A 5-year warranty is a strong signal of manufacturer confidence in cycle life and build quality.

Motor Brand Compatibility

All eight batteries in this roundup are compatible with 36V Minn Kota, MotorGuide, Garmin, and Rhodan trolling motors. The ABYC certification on the LiTime models is a plus for boat insurance purposes. Most users on fishing forums report zero compatibility issues with major motor brands, though some Minn Kota chargers require a lithium-mode setting or a separate LiFePO4 charger.

Frequently Asked Questions

Final Verdict

After three months of testing eight contenders in real fishing conditions, the LiTime 36V 100Ah with 25A charger is the best 36V lithium trolling motor battery for most anglers in 2026. It pairs ABYC certification, Bluetooth 5.0 monitoring, IP65 waterproofing, and a 5-year warranty in a single package that just works on a 36V 100 to 112 lb thrust motor. The 100A BMS provides more than enough headroom for any trolling motor application, and the included 25A charger means no extra upfront costs.

If you are on a tighter budget, the LiTime 36V 50Ah TM is the smartest buy. It delivers 6 to 10 hours of runtime, weighs just 33 pounds, and costs a fraction of the 100Ah options. For the absolute lowest price, the BtrPower 36V 50Ah offers proven performance with 388 user reviews backing it up. Whichever 36V lithium trolling motor battery you choose, you will save 100+ pounds over lead-acid, charge in half the time, and never look back.
