Running four batteries, best way to wire them up?
Currently have 2 northstar group 31 Agm batteries set up with the standard guest 1,2,1+2 battery selector isolator(whatever you call it) with a 2 bank charger wired up to each one of them. Looking to add two more to my boat and want to know what's the best way to wire these guys in. I was thinking about two banks with both batteries added in parallel but not sure, can anyone lead me in the right direction? Looking to power 4 JL MHD amps. Thanks,Nick.
