This is posted in gear heads too, but I think the traffic is a little slower over there.
I have dual batteries and use a Perko switch. My question is - If I want to charge both batts at the same time, can I just put the selector switch to "both", hook the cables to just one battery and get the job done? Do I save any time doing it this way? I'm thinking it may not be the way to go if one battery is less discharged than the other. As always thanks in advance
