hey Al,
why worry about a 2 bank charger when you have your relay? Can't you just hook up a charger to one of your batts and it will charge both?

What is the benefit to charging each of the batts seperately? Maybe there's a thread on the issue but I had a guy local try and tell me that there really is no need to charge the batts seperately. Just hook up a charging source to one and not worry about it?
