I have two Victon SuperPack 200Ah batteries connected in parallel with a BMC-712 to a Cyrix-Li-Ct and my Sprinter's lead battery. I understand that the power flow is supposed to be one way but but this morning the Sprinter's battery is dead. I drove the Sprinter yesterday.
Since the SuperPacks have an internal BMS, I dont have an external/second BMS. I was advised to wire the Cyrix with battery to Sprinter battery, Lion terminal to one of the SuperPacks, then terminal 86 to ground and 85 to the one of the SuperPacks's postive terminal. Is this correct?
Advice is greatly appreciated.
