Trolling Motor Batteries

Check the motor label or the number of batteries wired in series in your current bank — one battery is 12V, two in series is 24V, three is 36V. Our 24V, 36V and 48V lithium batteries replace those series banks with a single case.

On most rigs, yes. A 36V lithium battery does the work of three 12V batteries wired in series, which saves a substantial amount of weight and frees up the tray space.

Add up the amp draw of everything the battery has to run, multiply by the hours you want between charges, and leave some headroom. If you would rather not do the math, our team will size it with you over the phone.

Group size describes the case dimensions and terminal layout, not the capacity. Match the group size stamped on your current battery — every product page lists the group size and dimensions so you can confirm it fits the tray you already have.

A lead-acid charger can undercharge a lithium pack and shorten its life. Use a lithium-compatible charger — everything in our Lithium-Compatible collection is profiled for LiFePO4.

None of the routine watering or terminal cleaning that flooded lead-acid requires. The built-in BMS manages charge and discharge protection automatically.

Terms vary by product line — the term for each battery is listed on its product page, and the full details are on our Warranty Information page. Register your battery online after purchase to activate coverage.

Call our US-based battery team on 1-800-827-3232 before you order. Tell us the machine, the tray you are working with and how long you need to run between charges, and we will point you at the right part number, or message us.
