5S Battery Management Module (BMS) for 18V/21V 20A Lithium-ion Batteries

5S Battery Management Module (BMS) for 18V/21V 20A Lithium-ion Batteries Description

① The protection board is used for 5S lithium-ion batteries, primarily in power tools. ② It uses an integrated circuit specifically designed for 5S lithium batteries as its processor to monitor the voltage, charge and discharge current, and ambient temperature of each battery in real time. ③ It provides robust protection during charging and discharging, including protection against overcharging, over-discharging, and short circuits. ④ It is characterized by low power consumption, with an operating current of approximately 25 µA and a standby current of approximately 6 µA. ⑤ Selecting and using a suitable protection board is essential to extending battery life. ⑥ Charging Voltage: 19/21V ⑦ Charging Voltage per Cell: 3.8/4.25V ⑧ Continuous Discharge Current: 8-20A ⑨ Overcharge Protection Delay: 1s ⑩ Note: This protection board is designed to protect the battery from overcharging and over-discharging. It does not replace the charger. You still need a charger specifically designed for lithium batteries! After connecting the cables, the battery must be charged before use. ⑪ Color: Green ⑫ Material: Printed Circuit Board ⑬ Package Contents: 1 x Battery Charge Protection Board. Only the above-mentioned contents are included; other products are not included. Note: The color of the item in the photo may slightly differ from the actual color due to light reflection and your monitor settings. A margin of error of +/- 1-3cm is possible.
