# TP4056 2-in-1 Lithium Battery Charging Board Module Ideal for 18650 li-ion battery charging, overcurrent protection, DIY electronic projects and power supply modification, this module is a must-have for electronics hobbyists.

## Key Features ✅ Dual function design with both charging and battery discharge protection, supports simultaneous charging and discharging ✅ Equipped with TYPE-C USB female connector at the input end, works directly with standard mobile phone chargers to charge lithium batteries ✅ Reserved input voltage wiring solder points for extra convenience during custom DIY projects

## Usage Guide ### Important Notes - When connecting the battery for the first time, you may get no voltage output between OUT+ and OUT-. Just connect a 5V power source for a short charge to activate the protection circuit. You also need to do this if you short B+ and B- then reconnect the battery. - Use a mobile phone charger with 1A or higher output, otherwise charging may not work properly.

### Wiring Steps 1. The TYPE-C USB female port and its adjacent + and - pads are 5V power input terminals, connect to 5V power here. 2. Connect B+ to the positive terminal of your lithium battery, B- to the negative terminal. 3. Connect OUT+ and OUT- to your load, e.g. positive and negative terminals of a mobile boost converter or other electronic loads.
