1. What type of charger should I choose?
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. LifePo4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
2.The relationship between Battery capacity and BMS current?
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 batterycapacity.
3.Whether my BMS damaged?
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.
4. Do you produce Hardware BMS or Smart BMS?
We produce both Hardware bms and smart bms.
5. What accessories should i buy for smart BMS？
We have bluetooth module for App use, and communication box tool(UART/RS485) for PC use.
And LCD display (UART/RS485) available too. Further question, please contact our customer service.
