So with time on my hands I have gotten bored. Today I decided to build a few things that I had been wanting to do. The first pics are the "Go Battery" in a .50 cal can, the next are the "light in a box". The battery box uses a 33ah SLA battery and has a voltmeter, dual USB charging, and 2 marine lighter sockets. The light box uses a 17ah SLA and a single 17 watt /1980 lumen 600K flood light. It easily lights a room or work area and I know will run for 8 hours (tested).
