True mini lithium battery charge and discharge protection module

Overview

It has been verified that
the two pads on the back of the current Type-C female connector are for discharging, but they can also be used for charging. The two small pads on the bottom connect to the battery.
A red light indicates charging;

the following image is a test image of the first version.

A green light indicates a full charge;

the following image shows the actual dimensions.
