    We do a lot of dry camping and currently have 2 x 12v batteries in parallel. Batteries are approaching end of life and I’ll be replacing them shortly. I have the space for a third battery, and am thinking of going with 3 x 12v to maximize amp hours. However, I’ve never seen or read about such a configuration. Is there any reason I shouldn’t do this?

    Leon-
    We have 4 deep cycle marines in our 5th wheel; no issues last year. As long as you hook them up in parallel and not series, you would be fine. The reasoning being that if they're in series, you end up with 24v system and anything with a max of 12v in your unit MAY get fried. The other thing you should do is hook pos. up to first battery and ground to last, which will drain all batteries equally
