Re: Need wireing diagram to set up 2 batteries and perko switch
What I do with my boat is cruise on both, and when we get somewhere to anchor for a while, I switch to battery 1 to run the stereo and whatever else. When it comes time to go, flip to battery 2, fire it up, then switch it to both so both batteries charge on the run home. When on shore power, ours has a charger so the batteries stay topped off. If you go with two batteries, what I'd suggest is having one starting battery, and one deep cycle. Anchor on the deep cycle so you can run accessories for longer, then start on the starting battery when its time to go.
