⚙️ How the TP4056 Charging Module Works

The TP4056 charging module follows a constant current / constant voltage charging method, which is the recommended charging technique for lithium-ion batteries.

Charging Process

1. Constant Current Stage

   • Battery charges with a steady current up to 1A.

2. Constant Voltage Stage

   • When battery voltage reaches 4.2V, charging switches to constant voltage mode.

3. Charge Termination

   • Charging stops automatically when the current drops below the threshold.

This charging method ensures maximum battery life and safety.

The module also includes a protection IC and MOSFET, which help protect the battery from unsafe conditions.
