Hello,
I have made myself a mobile power pack with 4 x Victron Smart LiFePo4 batteries, (12.8V 200Ah), wired in series, powered from a Multiplus II 48V inverter with BMS installed.
I have the Victron app so can monitor each battery using Bluetooth.
My question is: when in inverter mode (mains power off, load powered from the batteries) should I expect all batteries to discharge evenly?
At least one battery discharges faster that the others (not always the same one), the BMS then picks up under-voltage and shuts down the system. However, when I look at each battery they are at varying states of charge. Is this normal in a series system? Presumably I am not getting the full capacity of the system?
Thanks for the help
Nigel
