You can charge it over USB, check with a button, and even program so it behaves exactly how you want. We go end-to-end: picking the core ICs (charger + protection + fuel gauge), wiring it up in KiCad, fabricating the PCB on a CNC, soldering everything together, then designing and finishing a clean 3D-printed enclosure. To top it off, I made dockable add-ons with fixed boost regulators so you can get common output voltages on demand to power any of your projects.

If you build one (or improve it), drop a comment! I’d love to see your version. Join the Maker Vibe! #DIY #Electronics #BatteryPack #KiCad #3DPrinting #MakerVibe #Microcontroller #CNC
