    Is 27amp wire good for connecting two 12v batteries under seats on my Hymer.

    no idea what size 27amp cable is.. cable is sized in mm2 ..not amps.

    to size accurately you need to know length and max current ,

    for example.. 1 mt length and max current of 50 amps requires 25mm cable
    increase the length to 2 mt , same current and to keep losses the same, you need 35mm cable

    in any case.. interconnecting battery cable should be at least as heavy as the main battery feed cable..

    useful sizing tool
