I have had 12 v and 24 volt set ups. On my boat the lights, gps, bilge, livewell, and starter are on the the 1 battery. 24 volt just for the trolling motor (83 pound?). Can go all day easy and does great in the current seams for the walleye run. Can not say the same for my old 12 volt with aluminum boats set up. I would never go back. But if 24 volts is this great, what does 36 volts do?
