Just make sure that you go from #1 to BOTH & then to #2, not by the way of "OFF".
Best advice is to leave the switch set to both while running to insure both banks can be charged.

Except if you have a cell go bad in one battery.

Then the good battery will try to bring the bad one up and in turn kill both batteries. This is why I don't like this idea and install BEP Cluster switches.



How it works:
