Boat battery set up

[Pulleye16]

I went from two batteries, to three batteries, and want to go back to two batteries.


How do you set up your boat batteries if only running two?

Main motor (90hp)
Auxiliary equipment (radio/lights/etc)
Trolling motor
Fish finder

When running three batteries, I did one for the main motor and auxiliary equip. One for trolling and one for fish finder.

With only two batteries, would you do one for main motor, auxiliary, and fish finder, and one for the trolling motor?

Yup.  I have two for the bow mount and the other for main motor and acc.

Yeah, that's how ours is set up too. Only the TM is connected up front & everything else is hooked up to the outboard starting battery in the rear. We have room for 2 batteries in the front, so that's what we've always run. We used to run a 12v TM but we went 24v last season. The TM can cause interference on your graphs if they're hooked up the other way.

We only have 2 also, the trolling motor and front finder run off 1 and the main battery handles everything else including the main finder, bilge, live wells, radio, lights..
