Marine Batteries

Start with a battery that matches your motor

In our shop, we prefer a dedicated 24V or 36V trolling motor battery over wiring two or three 12V batteries in series. If you need more runtime, you can wire matching 24V batteries or matching 36V batteries in parallel, provided the battery manufacturer allows it. That adds capacity while keeping the voltage the same.

Running a brushed Minn Kota on lithium?

If you regularly run your brushed Minn Kota near full speed for long stretches, we recommend addressing that before switching to lithium. On models covered by Minn Kota’s lithium speed guidance, running above about 85% for extended periods can permanently damage the motor. Check the manual for your specific model.

If you spend much of the day on 9 or 10 just to hold the boat in wind or current, consider a motor with more thrust. That might mean stepping up from a 24V motor to a 36V motor with a matching battery setup.
