FAQ
Q. What type of charger should I choose?
A. Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge. Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
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 a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.
Q. Whether my BMS damaged?
A. If you want to judge if the BMS is damaged, please take the folowing 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 displyed as no charge, no discharge, no discharge while the battery has voltage.

Q. Are the CANbus ports on these BMS'es "electrically isolated"
A. Yes. Electrical isolation is also electrical isolation. The so-called electrical isolation is to electrically isolate the power
supply from the electrical circuit, that is, to isolate the electrical branch circuit from the entire electrical system, making it
an electrically isolated, independent, ungrounded safety system. In order to prevent the danger of indirect contact with
electricity when the exposed conductor fails and is electrified.
