I have a 12v 45lb thrust mimnkota, I need 2 GOOD batteries, one to Run the trolling motor, another for lights and fish finder, and also a back up trollin battery.
Id prefer an onboard charger, but anything will do as long as I can plug it in and forget it. Dont want to overcharge and destroy batteries, and I also need to know how to make my outboard (40HP) to charge the batterys as well,
It's all confusing too me, any help would be appreciated!
