Re: Battery switch
If the battery charger is one that senses each battery individually you don't want the ACR (combiner) to parallel them. The switch solves that.
If the battery charger has 2 outputs but does not sense batteries individually the switch is not needed.
If you forgot the switch the ACR would parallel the batteries as it is designed to when the voltage rises.
