If you want to run both batteries at the same time, then you'd likely have to hook them up in series .. which if i remember correctly would be .. positive on battery 1 to starter solenoid, negitive battery 1 to positive battery 2, negative battery 2 to ground

double check that first .. don't quote me

mmm, i think series will give you the voltage. So it means it would make it 24V instead of 12V.

what type of voltage you need? are they for your Amps or what, kind of power rating (ampere) you need? in series 24 volt or parallel 12 volt (higher ampere)
