2S 3A Li-ion Lithium Battery 7.4V 8.4V 18650 Charger Protection Board Module

Description

1. 2S Configuration: Designed for use with 2-series (2S) lithium-ion battery packs, which typically consist of two 18650 cells connected in series.
2. Voltage Range: Supports a voltage range suitable for 2S lithium-ion batteries, typically 7.4V (when discharged) to 8.4V (when fully charged).
3. 3A Charging Current: Provides a maximum charging current of 3A, allowing for relatively fast charging of the connected 2S battery pack.
4. Charging Protection: Incorporates protection circuitry to prevent overcharging, ensuring that the battery voltage does not exceed safe levels during the charging process.
5. Balanced Charging: Some models include balanced charging capabilities, which ensure that each cell within the 2S battery pack is charged evenly, preventing cell voltage imbalances.
6. Discharge Protection: Offers over-discharge protection to prevent the battery voltage from dropping below a safe threshold, prolonging the life of the battery pack.
7. Short-Circuit Protection: Provides short-circuit protection to safeguard against accidental short circuits in the wiring or connections.
8. LED Indicators: Often includes LED indicators to display the charging status, such as charging in progress, fully charged, or fault conditions.
9. Compact Design: Designed to be compact and space-efficient, making it suitable for integration into custom battery packs or charging solutions.
10. Input/Output Terminals: Typically features labeled input and output terminals for easy connection to the power source and the 2S battery pack.
11. DIY-Friendly: Ideal for DIY enthusiasts and hobbyists who want to create their own 2S lithium-ion battery chargers or protection modules.
12. Temperature Protection: Some models may offer temperature protection, which monitors the battery temperature during charging and discharging to prevent overheating.
