4S - 16V - 6A - BMS PCM PCB Module for Charging and Protection of Li-Ion Cells - for 18650 Cells

Electronic system protecting Li-ion batteries 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.
