12V DC Ammo Can Power Box v1.0

IMG_5260

I wanted to build a custom rugged battery box on a budget for amateur radio communications and emergency charging. The ammo can was found in poor condition at an army surplus and was restored by sanding to remove rust, re-painting, and lubricating the rubber seal. I’m not yet satisfied with the internal fabrication and will continue to improve upon its design later. Future improvements to include: led switch, solar charge controller, improved mounting panel, volt/amp meter.
