This TP4056 1A Li-ion lithium Battery Charging Module with Circuit Protection – Micro USB is a tiny module, perfect for charging single cells that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 5V 1A charge current then cut off 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.
