Q: The relationship between battery capacity and BMS current?A: There is nodirect 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
yourcharge 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 disply 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.
