Bill of Materials
Description
This is a compact 12 V battery pack I designed for my air cannon, powered by a single 18650 cell. The enclosure has dedicated space for both a TP4056 charging module and an MT3608 boost converter. I also added a red power‑indicator LED and a main switch.
The switch disconnects the charging circuit as well, ensuring the battery won’t slowly drain during long‑term storage.
The lid is secured with M3 hardware and heat‑set threaded inserts for a sturdy and reliable fit.
Boost converter: MT3608
Charging module: TP4056
