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:

1. Ensure the battery voltage is within the 3.7V range (supports 3.6V/3.7V lithium batteries).
2. Use the nickel strip to weld B+ and B- to the battery's positive and negative terminals, ensuring a secure connection.
3. Connect P+ and P- to the load or charger, matching the positive and negative terminals.
4. 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.
