Frequently Asked Questions

Can I use a 24V lithium battery with my existing trolling motor charger?

It depends on the charger. Most lead-acid chargers are not compatible with lithium batteries because they use different charging profiles. We recommend using a charger specifically designed for LiFePO4 batteries. Some lithium batteries have built-in BMS that can accept a lead-acid charger, but it is safer to use a lithium-compatible charger to avoid damage and ensure full charge.

How long does a 24V lithium trolling motor battery last on a single charge?

Runtime depends on the battery capacity (Ah), motor thrust, speed setting, and conditions. As a rough estimate, a 60Ah battery can run a 55 lb thrust motor on medium speed for about 4-6 hours. Higher capacity like 100Ah can double that. Lithium batteries maintain consistent voltage, so you get full power until depletion, unlike lead-acid which gradually loses power.

Are lithium trolling motor batteries safe?

Yes, when used properly. LiFePO4 chemistry is inherently stable and less prone to thermal runaway than other lithium-ion types. Quality batteries include a BMS that prevents overcharging, overdischarging, short circuits, and often low-temperature charging. Always follow manufacturer guidelines and use a compatible charger.

Can I connect two 12V lithium batteries in series to make 24V?

Yes, you can, but it is not recommended unless the batteries are specifically designed for series connection (like some Dakota or Battle Born models). Using two separate 12V batteries in series can cause imbalance over time, leading to reduced life. A dedicated 24V battery has a single BMS designed for the pack and is generally safer and more reliable.

What is the weight difference between lithium and lead-acid for 24V trolling motor batteries?

Lithium batteries are typically 60-70% lighter than equivalent lead-acid. For example, a 24V 60Ah lithium battery weighs around 13-15 lbs, while a comparable lead-acid (two 12V 60Ah in series) weighs about 50-60 lbs. This weight reduction improves boat performance and handling.
