Lithium Battery Charging Module

TP 4056 5v Micro USB 1A 18650 Lithium Battery Charging Module

This tiny TP 4056 5v Micro USB 1A 18650 Lithium Battery Charging Module

is perfect for charging single cell 3.7V

1 Ah or higher LiPo cells such as the 18650s

that do not have their own protection circuit.

Based around the TP4056 charger IC and DW01 Deep

Drain Battery Protection IC this module offers a 1A charge current.

The module cuts off the charging current when finished.

Furthermore when the battery voltage drops below 2.4V the protection

IC will switch the load off to protect the cell from running too

low of a voltage – and also protects against over-voltage and

reverse polarity connection (it will usually destroy itself instead of the battery)

however please check you have it connected correctly the first time.
