Hi, I have a narrowboat with 4 x 110ah lead acid batteries monitored by a BMV 702 and connected to a MPPT 100/50 Victron controller and a Multiplus 12/3000/120 Charger/Inverter.
I am looking to optimise the performance and life of the batteries and came across the combination of Lead Acid and Lithium Batteries in parallel which appear to complement their charactistics for optimum performance and Lead Acid battery life.
It appears that the recharge for the batteries is where this system falls down. Am I correct?
If this is the case, has anyone tried to separate the batteries during charging then reconnect for discharge? Would this overcome the problems in charging?
Your advice gratefully recieved
