Attention when connecting:
When we connect BMS with cells or disassemble BMS from battery pack, the following order and regulations must be complied with to avoid damage of components of BMS and problems of not protecting of cells.
In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each battery voltage ≦0.05V, IR≦15 mΩ,capacity≦30mAh) to make sure the better consistency of the battery.
Cell must be connected in parallel first, after then connected in series
Order of connection:
Step1: Connect charging /discharging wire , battery pack negative wire
Step2: After confirm the wires are connected OK, plug the connector cable in the BMS
DO not plug Connector cable in the BMS before connect wire!!
Attention: ESD protection during work.
