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: MT3608Charging module: TP4056 Boost MeBoost?
