The Centaur charger, 12/40 has 3 outputs. If The engine battery, AGM, is connected to O/P 1 and the Lithium house batteries are connected to O/P 2 and 3 is this a safe option as both use the AGM setting of the Centaur for battery chemistry?
Do the three outputs work independently with respect to Bulk/Absorption/Float? Meaning if the engine battery is fully charged it goes to float and the outputs 2 and 3 remain at Bulk until the house have reached appropriate voltage to change to absorption/Float?
Is the another option to have 2 x Lithium and 1 x AGM safely being charged from the Centaur?
