I am planning an Optima 34D starter/windlass bank and also have a pair of 100Ah LiFePO4’s I’d like to use as a secondary house bank. Charging/float voltages are 13.8-15.0V/3.2-13.8V and 14.4V/13.4V, respectively; the Optima batteries should be charged at maximum 10A each. A 300Ah LiFePO4 primary house bank would supply the B2B charger and is served by a 100A Balmar w/MC-618 regulator.
Might I be able to charge the starter/windlass bank and the secondary LiFePO4 bank with a single Orion-tr 12/12/18A charger output (set at, say, 14.2/13.4V) through a 1-off-2 switch?
