Chewing gum battery 1.2V charger

Overview

This project is to solve the problem of chewing gum battery charging. Only made one battery. If there are many batteries, you can directly connect several modules in parallel. The charging current can reach 1A charging current. Fully meet the needs of many devices. I can't find the packaging of the battery, and I don't want to draw it. But in actual use, this can be done by welding two small copper pieces at 90 degrees. I enlarged and strengthened the soldering pad. No need to buy it.
