1S 3A 3.7V BMS PCM PCB Li-Ion Charging & Protection Module

Electronic system protecting 1S battery against discharging and at the same time a charger for these batteries. It allows you to build a safe battery pack that does not need to be charged with special Li-ion chargers.
The 2 in 1 module will keep the cells in the best conditions, preventing them from overcharging and over-discharging. One module replaces the charger and the security module here.
