This compact board supports a maximum continuous discharge current of 2-3A.
Key Features:
- Nominal voltage: 3.7V
- Overcharge protection: 4.25V±0.05V
- Over-discharge protection: 2.3-2.35V
- Maximum continuous discharge current: 2-3A
- Static current: ≤3µA
- Operating temperature: -40°C to +85°C
- Compact design with nickel strip for easy installation
Wiring Instructions
This protection board is designed for 1S lithium battery configurations. Follow the wiring instructions below for safe and optimal performance:
- B+ (Positive Input, Red Line): Connect to the battery's positive terminal.
- B- (Negative Input, Black Line): Connect to the battery's negative terminal.
- P+ (Positive Output, Red Line): Connect to the load or charger's positive terminal.
- P- (Negative Output, Black Line): Connect to the load or charger's negative terminal.
Wiring Steps:
- Ensure the battery voltage is within the 3.7V range (supports 3.6V/3.7V lithium batteries).
- Use the nickel strip to weld B+ and B- to the battery's positive and negative terminals, ensuring a secure connection.
- Connect P+ and P- to the load or charger, matching the positive and negative terminals.
- Check all connections to avoid short circuits, then power on for testing.
Note: Strictly follow the wiring instructions to avoid short circuits or incorrect polarity, which may damage the board or battery.
