TP4056 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module

Product Description

TP4056 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module

Description

This tiny module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s that do not have their own protection circuit. Based around the TP4056 charger IC and DW01 Deep Drain Battery Protection IC this module offers 1A charge current. The module cuts off 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 at 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.
