TP4056 - TC4056A Lithium Battery Charger and Protection Module

This module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery the module also provides necessary protection required by lithium batteries. See below concerning the protection features this module provides. Protection Features This module uses the TP4056 / TC4056 Li-Ion charge controller IC and a separate protection IC. There are other types of modules on the market that use the TP4056 / TC4056 but lack any protection circuits or ICs to provide the necessary protection needed with lithium batteries. This module uses both the TP4056 / TC4056 and the DW01A Li-Ion battery protection IC, which together in combination provide the following protection features: Manage the constant current to constant voltage charging of a connected lithium battery Over-discharge protection - keeps your battery from being discharged below 2.4V, a healthy minimum voltage level for your bat
