Q: What type of charger should I choose?
A: Lithium battery must choose a specific charger, do not use a charger for lead-acid battery, as lead-acid chargers may have MOS with high pressure breakdown protection, which will not protect BMS from overcharge. LiFePO4 battery charger voltage = battery string No. X 3.6V, while Li-ion battery charger voltage = Battery string No. X 4.2V.
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 it relies on continuous current. If your engine is powerful, you should choose a high current BMS, it is not reliant on battery capacity.
Q: Whether my BMS is damaged?
A: To judge if the BMS is damaged, please take the following steps: test if each cell voltage is the same with a voltmeter? If the cell voltage difference is over 1.0V, the fault is displayed as 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 damage is displayed 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. This is to prevent the danger of indirect contact with electricity when the exposed conductor fails and is electrified.
