5pcs 5V 1A USB Type C 18650 TP4056 Lithium Battery Charger Module Charging Board

Newest UK Hayatec Type C TP4056 module is a complete single-cell Li-Ion battery with a constant current / constant voltage linear charger circuit board. The SOP40 package with heatsink on the bottom of the TP4056 and fewer external component make the TP4056 TYPE C module ideal for portable applications. Suitable for USB power and adapter power supplies. 

Due to the internal PMOSFET architecture and anti-reverse charging path, no external isolation diodes are required.
Thermal feedback automatically adjusts the charge current to limit chip temperature during high power operation or high ambient temperature conditions. 

The charging voltage is fixed at 4.2V, and the charging current can be externally set by a resistor. When the charging current drops to the set value of 1/10 after reaching the final float voltage, the TP4056 will automatically terminate the charging cycle.

When the input voltage (AC adapter or USB power) is removed, the TP4056 automatically enters a low current state, reducing the battery leakage current to less than 2uA.

The TP4056 can also be placed in shutdown mode when there is a power supply, reducing the supply current to 55uA.
Other features of the Hayatec Type C TP4056 module include battery temperature sensing, undervoltage lockout, automatic recharge, and two LED status pins for charging and termination.

NOTE:
1. Ampere meter can only be connected to 5v input end of the module.
2. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.
3. The connection wire should not be too thick.
