FAQ
Q: How do I know what material or type my battery is?
A: Please look your battery body, if the normal voltage of your battery shows 3.2V, the battery is LiFePo4. If the normal voltage of your battery shows 3.6V or 3.7V, the battery is Li-ion or Li-polymer battery.
Q: Is this BMS suit for my battery?
A: First, please confirm that how many series you cell is in your battery pack. The BMS you buy must be same series as your battery pack.
Then please tell me how many Amps the working current needed. I will choose the best suitable one for you.
Q: What Amps should I choose for the BMS?
A: It depends on the motor power and controller current limit for electric vehicles. Such as less 250W choose 15A, less than 500 W choose 20 A, less than 800W choose 30A. If more than 1000W, please discuss with me. Protection current cannot be less than controller current limit.
Q: What is the Common port and Separate port? what is the difference?
A: We take 10S 36V 20A BMS for example:
Common port 20A means your charge cathode and discharge cathode are connected in the same point end (our P-), charge cathode and discharge cathode are used in the common connection port, so the charge current and discharge current are same as 20A.
Separate port is separately connected by charge cathode (our C-) and discharge cathode (our P-), so the charge current and discharge current are different, discharge current is 20A, charge current is 10A.
Q: The relationship between battery capacity and BMS current?
A: There is no direct relationship between battery capacity and BMS current, big capacity doesn't mean big current, but rely on continue current, that is to say if your engine is powerful, you should choose high current of BMS, it is not relied on battery capacity.
Q: How should I choose the right charger?
A: LiFePo4 battery charger voltage = number of battery strings X 3.2V,
Li-ion battery charger voltage = number of battery strings X 4.2V.
