1S 3.7V 3A 2MOS BMS Li-ion 18650 Battery Protection Board
Description:
The "1S 18650 Li-ion Lithium Battery BMS Charger Protection Board for 3.7V Battery" is a specialized circuit board designed to manage and protect single-cell lithium-ion (Li-ion) battery packs with a nominal voltage of 3.7 volts, typically constructed using 18650 battery cells. Here's a detailed description of its features:
-
1S Configuration: This indicates that the protection board is designed to manage a battery pack consisting of a single lithium-ion cell. Each cell typically has a nominal voltage of 3.7 volts, resulting in a total nominal voltage of 3.7 volts for the battery pack.
-
Battery Management System (BMS): The protection board acts as a BMS, overseeing the operation of the lithium-ion battery pack and ensuring its safe and efficient performance.
-
Charging Protection: The BMS provides protection against overcharging of the battery cell during the charging process. Overcharging can lead to reduced battery life, overheating, and in extreme cases, safety hazards such as fire or explosion. The protection board monitors the cell voltage and terminates the charging process when the voltage reaches a predetermined threshold to prevent overcharging.
-
Discharge Protection: It also offers protection against over-discharging of the battery cell during discharge. Over-discharging can damage the battery cell and reduce its lifespan. The protection board monitors the cell voltage during discharge and disconnects the load when the voltage drops below a safe threshold, preventing over-discharging.
-
Temperature Monitoring: Some BMS boards may include temperature monitoring functionality, which helps prevent overheating of the battery pack during charging or discharge. If the temperature exceeds safe limits, the protection board may take corrective action, such as reducing charging current or disconnecting the load.
-
Balance Charging (Optional): Depending on the specific model, the protection board may feature balance charging capability. Balance charging ensures that each cell within the battery pack receives an equal charge, promoting longevity and performance consistency.
-
Compatibility: The protection board is specifically designed for use with 18650 lithium-ion battery cells, which are commonly used in various electronic devices and battery packs due to their high energy density and reliability.
Overall, the 1S 18650 Li-ion Lithium Battery BMS Charger Protection Board for 3.7V Battery provides essential protection and management functions to ensure the safe and efficient operation of single-cell lithium-ion battery packs, making it suitable for a wide range of applications, including portable electronics, power banks, and battery-powered devices.
