Nowadays, BMS suppliers are setting the balance current more safe than before. For example,
the balance current for 36V 10Ah or 48V 10Ah battery BMS, it is about 40~50mA. A few years
ago, almost all BMS manufacturers are setting balance current 70~80mA, which is more
efficient but the balancing will bring too much heat which may affect the performance of
BMS even damage the BMS or battery pack. For small packs like 24V 3-5Ah, the balance
current is about 15-25mA.
We advise you to confirm the balance current before ordering.
