4S - 16V - 5A - BMS Module for Charging and Protection of Li-Ion Cells - for 18650 Cells

Electronic system working as a protection of the batteries against excessive discharge. This module will also provide a charger function 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 was created to keep the cells in the best condition, preventing them from overcharging and over-discharging. One module replaces the charger and the protection module here. Product features Short circuit protection. Overcharge protection. Over-discharge protection. Overcurrent protection. They can be used for various 3.7V lithium cells. Compact size and lightweight. Ensuring protection of the package.
