Our trawler has a 12v, six-battery FireFly 900Ah L15+ house bank (6S2P configuration) and a 12v, two-battery FF G31 machinery bank (2P configuration).

I would like to charge both banks in parallel off of one Balmar 210A 94-Series large frame alternator/MC-614 regulator. Being as they are the same carbon-foam chemistry and charging voltages, should be Ok? The large capacity difference shouldn't be a problem either?
