TP4056 Module has protection against over/under charge

Separate connections for battery and load

28mm x 17.5mm PCB

This Lithium Battery Charging Board is engineered for efficient charging of 3.7V lithium batteries.

Compact and weighing practically nothing, it incorporates a powerful 1A high current linear charging system,

delivering fast and reliable charging.  This product includes a Type-C interface for power input.

This well-designed charging module boasts an operational input voltage range of 5-6V, providing reliable and steady charging.

It's design assures an automatic termination of the charging cycle when the final float voltage is reached, and charging current decreases to 0.1A (100mA).

The charging cycle automatically resumes when the battery voltage falls below 4.05V, corresponding to 80-90% of the battery capacity, guaranteeing a full battery.

When your battery voltage dips lower than 2.9V, this unit initiates a pre-charging process with a 0.1A (100mA) current to safely bring your battery up to a safe voltage for full 1A (1000mA) charging current.

This Charging Board is built with an integrated protection circuit, providing over-discharge protection, and over-current protection, ensuring the safety and longevity of your lithium battery.

The load is disconnected when the battery voltage goes below approx 2.6v, and the load is reconnected when the battery voltage rises to approx 3.0v.

The board is simple to use, simply connect it to the charger via USB-C, or power supply via 5V input pins, and it's ready to go.

Despite its numerous functionalities, the board is surprisingly compact with dimensions of 28×17.5mm.
