⚙️ How the TP4056 Battery Charging Module Works

The TP4056 Battery Charging Protection Module uses a linear charging method with constant current and constant voltage control. When a battery is connected, the module initially charges it with a constant current. As the battery voltage approaches 4.2V, the charger automatically switches to constant voltage mode, gradually reducing the current until the battery is fully charged.

In addition to charging, the onboard protection IC and MOSFETs continuously monitor battery conditions. If the battery voltage goes too high, too low, or if a short circuit occurs, the protection circuit automatically disconnects the load to prevent battery damage.
