Overview

Type	Integrated

4S 40A Lithium Battery BMS Protection Card Standard Version Battery Li-ion 18650 16.8V Suitable for 4 series 18650 batteries. Does not charge batteries. For battery protection. Takes on the balancing task. With this module, you can charge high-capacity 4S lithium batteries quickly. Thanks to the voltage protections on it, it protects your batteries from charging at high voltages and also prevents current from being drawn from your batteries that are about to run out, preventing damage to the batteries. Batteries can definitely be charged at limited currents. Battery charging without current control causes the life of the batteries to decrease. Similarly, drawing high current from the batteries quickly damages the batteries. Although bms products seem to charge the batteries, they do not control the current. It is appropriate to use them only for battery protection purposes. You need to charge your batteries with your bms cards with a current control source. Battery charging current should be at levels such as 1/10 2/10 of the battery capacity. Remember, very high current charging or discharging will reduce battery life while gaining time/power.
