Re: battery bank dual charger or triple charger?
The paralleled house bank (Bat A and Bat B) can be charged as one battery; run the positive charger lead to positive post on bat A and the negative charger lead to negative post on battery B. You could use an ACR (automatic charging relay) to charge the start battery without using a multibank charger. Best battery life would be obtained with a "smart charger", and separate charging of house bank and start bank. Temperature sensors add a safety feature if you're selecting a new charger.
