I'm currently upgrading from two separate engine batteries (with link) that also lower the domestic circuits. Looking at the schematics for the Cyrix it shows the charger connected to only the domestic bank. Is this the best way to do it or can I connect both banks to the charger without messing up the working of the Cyrix or the BMV?
Hi Steve. There's probably no technical reason you couldn't do that, but if you're using each bank in a totally different way, like your starter batt(s) for starting/standby/mission-critical, and deep-cycling your house batts, then they might be better set up with the Centaur feeding the house batts with the cycle-charge regime and just topping off the engine batt with the Cyrix's milder charge regime.
Depends exactly what your doing with each. The Cyrix has plenty grunt, and using it alone might simplify the wiring a little. The Centaur's outputs are supposedly 'isolated', but you'd want to make sure that one batt can't feed back to the other through the 'common' connections.
