Three Into One
One Battery Where Three Used to Sit
Thirty-six volts is the classic big-water trolling motor bank and a common golf cart configuration. Replacing three lead-acid batteries with one 36V lithium pack saves well over a hundred pounds and removes every jumper from the equation.

Frequently Asked Questions
Choosing the Right Battery
Can I wire lower-voltage batteries in series instead?
You can, and plenty of systems still do — two 6V batteries in series make 12V, three 12V make 36V. A single higher-voltage lithium battery replaces that whole string with one case, one set of terminals and far less weight.
How many amp hours do I actually need?
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.
How do I know which group size I need?
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.
Charging & Maintenance
Can I keep using my existing lead-acid charger?
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.
What maintenance do these batteries need?
None of the routine watering or terminal cleaning that flooded lead-acid requires. The built-in BMS manages charge and discharge protection automatically.
Warranty & Support
What warranty comes with these batteries?
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.
What if I am still not sure which one to buy?
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.
