Q

Can this be used for a dual battery setup? If so how would I wire it?

A
  • Yes it can be used for dual battery Not knowing your vehicle you will have to tie it into something that's hooked to your ignition. Either the ignition itself or a driving light or anything that's on when the key is on. That way if you have one battery go bad you don't take out both batteries.
