I read that a Multiplus can charge a start bank as well ass the primary charging of the house bank, but only if they are the same chemistry. I have a 600Ah LFP bank and an 98Ah AGM start battery. Is there a way to charge the start battery with the Multiplus? (All 12V)
Read my FAQ in the DIY section which discusses how the trickle charger works and some of the pitfalls using it with lithium. If you have follow up questions just ask.
