MS 4S 14.4V 15A MOS 18650 Lithium Battery Charging Protection Board

The MS 4S 14.4V MOS 18650 Lithium Battery Charging Protection Board is likely a circuit board designed to protect a 4-series (4S) lithium-ion battery pack composed of 18650 cells during the charging process. Here are key features that are commonly found in such protection boards:

1. Overcharge Protection: Monitors the voltage of each individual cell and prevents overcharging by disconnecting the charging source when the voltage reaches a preset limit.
2. Over-Discharge Protection: Monitors the voltage of each cell during discharging and disconnects the load when the voltage drops below a safe threshold, preventing over-discharge.
3. Short-Circuit Protection: Detects and responds to short circuits in the battery pack, preventing potential damage.
4. Temperature Protection: Some protection boards include temperature monitoring to prevent overheating during charging or discharging. This helps enhance the safety of the battery pack.
5. Balancing Function: In 4S configurations, where multiple cells are connected in series, a balancing function may be included to ensure that each cell has a similar voltage level. This helps maintain the health and longevity of the battery pack.
6. MOSFETs: Metal-oxide-semiconductor field-effect Transistors are likely used in the protection circuit to control the charging and discharging processes, providing a fast and efficient means of disconnecting or connecting the battery to the load or charging source.
