Hello all,
I am planning to replace our 2 House 8D AGM 200ah batteries with 2 new Epoch DP12300H 300ah Lithium Dual Purpose batteries. Partially because our DC bow and stern thrusters are supplied from the house bank, (via the factory) which is really odd and I know it is killing these deep cycle batteries when blast them with a 525 amp draw multiple times on a windy day of trying to dock. Could you guys do me a favor and offer suggestions as to "where in the diagram" I would make the changes when I replace these 2 house AGM batteries to Lithium?...
I hand traced the wiring in the boat one weekend in order to develop a better understanding of the DC system and I created this Visio diagram for reference.
When I say changes, I say this because I plan to keep the one AGM 8D engine starting battery so think I have to modify the charging system somehow so the AGM battery is "isolated" so it is is charged with the correct AGM charging voltage and not the new Lithium charging voltage setting. Am I saying that right?
I know I can reconfigure the Alternators Balmar AH-5 External Regulator for Lithium and the Victron MultiPlus as well but understand that the AGM 8D shouldnt be charged with these new values..
I guess I am asking this...how does one reconfigure this system (add devices? DC to DC charger?) in order to charge both the new Lithium house bank and the AGM starting battery from the alternator with the correct charging profile...
your suggestions are appreciated...
