Main function:

Over charge protection, over discharge protection function, short circuit protection function, over current protection function,with band balance.

Connections:

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
