[QUOTE="Bruspark, post: 524685, member: 20106"] Start slowly. Are these 5 12V batteries or a single 50 V. The voltages you quote suggest lead acid but a clue would be good How are they charged and with what and to what voltage ? No. SOC from voltage is a generally poor indication due to various factors including battery temperature and time since charge SOC during a known rate discharge is a better bet Big falls in SOC or voltage during steady discharge at a rate that should last 5 hours or so generally indicate a cell fault or worn out battery (which also confuse chargers ) [/QUOTE]
