2S 8.4V 5A - BMS PCM PCB Module for Charging and Protection of Li-ion 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 module will prevent too much discharge and will not overload the connected cells. This is one convenient solution that will keep your package goals at its best.
