From the project

Hardware design, BOM, gerbers and 3D files for Li-ion-charger-with-protection designed by Soldered Electronics.

Lithium batteries are charged differently than regular batteries and devices. You’ll need a li-ion charger like this one to charge them. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery. Protection activated in cases of undervoltage, overvoltage and short circuit, which is enough protection for most batteries.
