Li-Ion charger cell 1A, module with IC TP4056

The charger is designed for charging 1-2 lithium cells with a voltage of 3.6V with a constant current of 1A up to a voltage of 4.2V, which it then maintains on the poles of the cell.


Product parameters:

- constant current charging. By changing the resistance Rprog-viz. Datasheet current can be changed in the range of 130mA-1A
- end of charging after reaching the terminal voltage of the cell 4.2V
- reconditioning charging with 130mA current if the cell terminal voltage level is <2.9V. When this voltage is reached, the module charges with a rated current of up to 1A
- optical check of charge status. The red LED indicates charging, the blue LED indicates charging is complete
- without short-circuit and overcurrent protection. We therefore recommend using cells with a protected circuit

Technical parameters:

- IO TP0456
- charging method: CC / CV
- input voltage: 4.5–6V
- input connector: mini USB
- charging current 1A (by changing the resistance it is possible to set 130mA-1A)
- end of charging: 4.2V
- reconditioning charging at <2.9V
- dimensions 17 × 20mm / 1.4g

The product is not a stand-alone unit, it requires professional installation.
