The short answer
The Dakota Lithium 12V 100Ah is the best all-around pick for anglers who want a long warranty and strong support. The LiTime 12V 100Ah TM is the best value, with low-temperature charge protection built in. Whichever you pick, pair it with a lithium-compatible charger like the NOCO GENPRO10X2.

How we built this guide
We compared batteries using manufacturer specs, BMS ratings, warranty terms, owner reports from trolling motor users and long-term reviews. We did not run discharge tests, so we treat cycle-life numbers as maker claims.
How many amp-hours do I need?
Most anglers with a 12V 55 lb motor are happy with 100Ah of lithium for a full day. Bigger motors run on 24V or 36V, which means two or three 12V batteries in series.
Lithium lets you use most of its rated capacity, unlike AGM. So 100Ah of lithium often feels like much more than 100Ah of AGM. See how long a trolling motor battery lasts for the math.
Dakota Lithium 12V 100Ah
Dakota Lithium is built around fishing use and offers a long USA warranty. It has a built-in BMS and is a common pick for trolling motors and ice fishing. Charger not included.

LiTime 12V 100Ah TM 3-pack
For 36V motors, a matched set of three batteries is the simplest way to build a bank. Matched batteries from the same batch are best for series use.

What should I look for in a BMS?
The BMS (battery management system) protects the battery. Its continuous current rating must be higher than your motor’s maximum draw.
A 100A BMS covers most 12V trolling motors. Check your motor’s max amp draw in the manual. If the BMS is too small, the battery can cut out at full throttle.
Who it’s for / who should skip it
- Lithium is for: frequent anglers, 24V and 36V setups and anyone saving weight.
- Skip lithium if you fish a few times a year and an AGM already meets your needs.
- Skip cheap no-name lithium if you cannot find clear BMS ratings and warranty terms.
What actually matters when buying
- Capacity: amp-hours sized for your motor and day length.
- BMS current rating: must exceed motor draw.
- Low-temp protection: needed for cold-weather charging.
- Physical size: fits your battery tray and box.
- Warranty and support: lithium is a long-term purchase.
- Marketing noise: 15000-cycle claims assume very shallow discharges.
NOCO GENPRO10X2
A waterproof 2-bank onboard charger with lithium and lead-acid modes. It charges two 12V batteries at once for 24V setups.

Watch-outs
- Use a charger with a lithium profile. A lead-acid charger may not charge fully or safely.
- Never mix old and new batteries or different brands in a series bank.
- Do not charge below freezing unless the battery has low-temp protection.
- Safety: lithium stores a lot of energy. Fuse the positive cable near the battery, secure it, keep it dry and do not use a damaged battery.
Which should you choose?
- Choose Dakota Lithium if you want the strongest warranty and support.
- Choose LiTime TM if you want value with cold-weather protection.
- Choose LiTime Bluetooth if you want to see battery status on your phone.
- Choose a matched multi-pack if you are building a 24V or 36V system.
Common questions
How long does a lithium trolling motor battery last?
In years, many makers rate thousands of cycles, so long service life is common with good care. Per trip, it depends on motor draw and speed.
Can I charge lithium with my boat’s alternator?
Some setups need a DC-to-DC charger to protect the alternator and charge lithium correctly. Check with the battery maker.
Is one 36V lithium better than three 12V batteries?
A single 36V pack saves space and simplifies wiring. Three 12V batteries are more flexible and can be cheaper. Both work.
Do I need a special battery box?
Any secure, vented box that fits works. The key is holding the battery firmly and protecting terminals.
