20A 18650 Lithium Battery Protection Board 11.1V 12V 12.6V

Description

1. Battery Configuration: Designed for use with a 3-series (3S) lithium-ion or lithium-polymer battery pack, which typically consists of three 18650 cells connected in series.
2. Voltage Range: Supports a voltage range suitable for 3S battery packs, typically 11.1V (when discharged) to 12.6V (when fully charged).
3. High Current Handling: Rated for a maximum continuous discharge current of 20A, making it suitable for applications that require higher power output.
4. Protection Functions: Provides comprehensive protection functions to safeguard the battery pack, including overcharge protection, over-discharge protection, overcurrent protection, and short-circuit protection.
5. Balanced Charging: May incorporate balanced charging capabilities, ensuring that each cell within the 3S battery pack is charged evenly, preventing cell voltage imbalances.
6. Low Voltage Cutoff: Monitors the battery voltage and cuts off power when the voltage drops below a safe threshold to prevent over-discharging and damage to the cells.
7. Overcurrent Protection: Protects against excessive discharge currents that could lead to battery damage or overheating.
8. Short-Circuit Protection: Provides short-circuit protection to prevent damage in case of a short circuit in the wiring or connections.
9. Compact Design: Designed to be compact and space-efficient, making it suitable for integration into custom battery packs or electronic devices.
10. Input and Output Terminals: Typically features clearly labeled input and output terminals for easy connection to the battery pack and the load.
11. LED Indicators: Often includes LED indicators to display the charging and protection status, helping users monitor the condition of the battery pack.
