Smart ACR’s are just another name for a DC to DC charger. Not to be confused with an ACR.
ACR’s combine banks. Smart ACR’s and DC to DC chargers charge the second bank with the appropriate profile for the second bank.
Much like Steve Mitchell I have a several secondary banks, start battery, crane battery, thruster battery. These secondary banks are charged via a SmartACR or DC to DC charger. It is impractical to run 40’ cable from the house bank to the front and back of the boat. Maintaining a secondary bank in the front and one in the back using a SmartACR means I only need to run 10gauge wire.
