This tiny 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 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.

Features:
Under Voltage Cut off / Deep Drain Protection
Over Current Protection
Adjustable Current Limit through R-Prog
Over-voltage charging protection
USB Micro Connector (with more commonly available USB cables)
LED Status Indicator for Charging / Full charge status monitoring
