The figures above come from the manufacturer’s Chinese data sheet (which has graphs in English) and there is an English simplified data sheet here, although some figures are different in this one.

Like the boilerplate TP4056 we covered recently, this might seem like little more than a physical manifestation of the typical application circuit from the chip’s datasheet.

The TP4056 IC is a complete constant current/constant-voltage linear charger for single cell lithium-ion/Lithium Polymer (LiIon/LiPo) batteries. Its SOP-8 package and low external component count make ...

It’s just a matter of replacing resistor R4, and a little bit of soldering! The official TP4056 datasheet even tells you the range of resistors to use (page 3).
