4S 14.8V 20A 18650 Battery Protection Board
The HXYP-4S-BMD1 is a compact square-shaped board that can hold four 18650 cells, making it suitable for a variety of high integration and low cost needs. Designed for use with different shaped 3.7V lithium-Ion batteries, this 4S 14.8V 20A Lithium battery Protection Board provides protection against over-charging, over-discharging, over-current and short circuits. With its versatile performance capabilities, it guarantees the absolute safety and reliability of your battery pack.
The 4S 14.8V 20A 18650 Battery Protection Board module allows for the connection of four 18650 batteries at once and is equipped with a BMS (Battery Management System) that monitors battery status and controls the charging and discharging process.
This charge controller offers protection against short circuits and over-discharge. Additionally, 4S 14.8V 20A 18650 Battery Protection Board includes a feature that automatically shuts off the power supply for any batteries that reach their maximum capacity. With a maximum operating current of 20 A and a quiescent current up to 10 μA, this BMS controller is reliable and efficient. The battery will stop charging at a voltage of 4.25 – 4.35 V and discharge at 2.3 – 3.0 V.
Should the supply voltage exceed the maximum permissible value, the charge controller will activate its “protection” mode. To restore functionality, either re-apply voltage to the BMS board’s input or wait for the charge controller to disable protection automatically.
