Re: Blue Seas ACR/"Add a battery" kit
Yes your 1/2/both switch is a better switch for your boat.
The ACR's purpose though is to eliminate having to change the switch to charge.
All charge sources - alternator, AC charger, solar go to the house bank. No charging goes through the switch.
Switching to both defeats the purpose of the ACR. Not necessary ever.
You could start on the house if you wanted to keep it real simple. But whatever position the switch is in makes no difference as the charge current is not passing through the switch. Both banks are getting a full charge.
You could start on either bank and even switching to off wouldn't do any damage.
