The .30-cal battery field box I recently posted came in very handy for this weekend’s Support Your Parks event. I had no problems running my setup, between this smaller box and my larger 20Ah box I had shared a while back.

The 100w Predator solar panel from Harbor Freight did an excellent job of keeping the larger box charged which was used to run a Xiegu G90. The smaller 7Ah box, since I didn’t build it with a solar charge controller inside, was daisy-chained to the larger box for charging and worked well to run my MacBook, iPhone (used as a portable hotspot for the laptop), and charge handheld radios throughout the weekend.

You can download the 3D print files for the distribution panel of the smaller box here.
