FAQ

Q: How to choose a suitable BMS for my battery packs? A: Please tell us following required details and we will advice for you:Battery material & Battery series & Capacity & working current & Application (For example: LiFePO4 BMS, 13 series, charge 40A, discharge 40A, application for e-bike 1800W.) 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: 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: 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: How should I choose the right charger? A: LiFePo4 battery charger voltage = number of battery strings X 3.6V, Li-ion battery charger voltage = number of battery strings X 4.2V.

Q: Whether my BMS damaged? A:If you want to judge if the BMS is damaged, please take the following steps, to test if each cell voltage is the same with voltmeter? if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displayed as no charge, no discharge, no discharge while the battery has voltage.
