I am thinking about adding another batt. to my system wondering what would be the easiest or best way to wire this new batt?? Just wondering how other people have multiple batts hooked up.
I'd make sure to fuse them up pretty well. I'd put a pretty big inline fuse on both ends of the positive terminal if it were me and the two batteries weren't directly beside each other... don't want to risk that wire shorting in the middle and starting a fire at either end of your wire.
Might want to look into a battery isolator if you are going that route - heard they tend to burn up though just an FYI.
Also, I would make sure to connect the grounds with a wire instead of just grounding both them - car isn't as conductive as thicker wire normally supposedly.
parallel them together and what ever the last batt in the bank is conect all your amps to it. That way you have an = charge/flow though your batts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
