Description
Description
The battery level indicator works without any problems, you can add it if you want, all parts are SMD.
battery outer template fiber laser engraved,
The indicator consists of 4 levels, but you can increase it, I am adding a link for the 3D printer box, you can download it from here.
Use it after taking security precautions and testing the connections. I'm using it for now.
