FAQ

Q :What is balancing function?

A :Working principle and function: when the battery voltage has a series to reach the voltage of balance open voltage of(lithium)4.18 V /(lifepo4)3.58 V(Need according the specification), the balance of the section on protection board will automaticallyopen, balanced protection board after open a well balancedresistance will with 42 mA to discharge (when the balance start thedischarge, protecting plate back there will be a slight heat, this is normal reaction) and thenCharge and discharge simultaneously,other section voltage didn't reach balance open voltage of 4.18 V / 3.58 V, is charged only, then the highest section to overchargeprotection voltage will be power-off protection, other batteries will be stop charging.This working principle can make the batterycharge in balance, so that the battery voltage balance effect, but if the battery voltage gap is large, then the function of balancefunction is basically no have.

Q :Relationship between battery capacity and current of BMS

A :There is no direct relationship between the battery capacity and the current of the BMS. That is to say,thelarger the motor, the larger the continuous current of the BMS you choose willbe,and the battery capacityisnot directly related
