Charging Two Battery Banks With One Alternator?


What is the best way to charge my (1) AGM starter battery and (1) lithium house battery from my alternator when the motor is running? I watched your videos and it looks like an isolator would work? Not sure? - Carl


Battery isolators do not modify voltage but just share a charging voltage. Your lithium battery and AGM battery will want a different charge curve. Instead of a battery isolator, consider a DC to DC charging converter between AGM and Lithium.
