You obviously have not looked at the original diagram the OP posted which is what I commented on and there are different ways to wire batteries in parallel. Depending on length and gauge the top diagram is preferred for longer and smaller gauge wire.rfuss928 said:Maxcamp8
It concerns me that the three folks that chose to offer detailed critique of your wiring diagram so far cannot see that the batteries are clearly shown wired in parallel. I would look elsewhere for electrical advise...
