This module is designed to charge rechargeable lithium batteries utilizing the constant-current/constant-voltage (CC/CV) charging technique. In addition to properly charging a lithium battery, the module also offers essential lithium battery protection. See below for information on the security features offered by this module. 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.
