Common Bass Boat Battery Setups

The most common setup for a bass boat is: The most common setup we see for bass boats with a 36 volt trolling motor recommends three 12V 50Ah batteries for the trolling motor and one 12V 125Ah battery for your engine starter and other equipment like a fish finder.

Smaller bass boats can manage with fewer batteries: If you were running a 24 volt trolling motor then you could use two 12V 100Ah batteries for the trolling motor and one 12V 125Ah battery for the engine starter and other onboard equipment.

Here are some more in depth examples based on common questions and setups we see

36 volt trolling motor and starter battery

24 volt trolling motor and starter battery

Now, let’s say you have a 24V 80lb thrust trolling motor and a 300 Yamaha hpdi; you have 2 batteries for the trolling motor and 2 cranking (perko switch for the cranking), and you’re looking for your best possible lithium set up. What do you need?
