This is a almost exact copy of the TP4056. The only difference is that this board has a better protection IC. Basicly it has a better protection sistem.
The TP4056 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...

This is the second version of my TP4056 based lithium battery charger module.
In v1.xx i used a linear voltage regulator (LM7805CV) which got very hot and limited the potential of the module a lot.
In v2.10 i replaced LM7805 with a switching counterpart (XL2011) which resolves most of the input issues allowing for a full range of 5V (via USB) and from 8-45V via the screw terminal or DC-Jack.
