I have a Balmar 250amp alternator, an MC-618 regulator, a lead acid starter battery and Victron 600Ah Smart Lithium house battery bank, controlled by a Smart 12/200 Victron BMS. I currently supply the starter battery from the alternator and have a link to the Smart BMS to charge the house bank. I was looking at charging the starter bank and the house bank using an Argofet and am considering using an Orion DC-DC charger between the Argofet and the starter battery to ensure that the starter battery is properly charges as the Lithium bank will consume much more power that the lead acid battery. I also am considering this set up as the alternator can produce up to 100 amps without an issue and am worried that the started battery on my current system will get overcharged quickly. Any advice appreciated.
