Portable Power Box
Description
I wanted a portable power box to provide power for my amateur radio activities. I purchased a couple of TalentCell LF120A1 12V 12Ah LiFePO4 batteries and the specs on these were excellent for my purpose. I needed a way to contain them and provide the connections I needed. I purchased a small ammo box at Harbor Freight for about $5 and the fit was excellent so I designed this project to provide a place to mount the power connections and hold everything in place. This worked well, but I saw the Sheffield Field boxes on Amazon and they come in a variety of colors. So I ordered one of them and it fit perfectly also. In the pictures is my orange Sheffield box. Assembly requires 2 #6 x 3/8 screws. These could be used with nuts, but the fit was close enough that there were not required required. They are used to attach the battery conver to the panel bottom. See the "combined" STL to see how everything is intended to fit together. The "Panel Top" and "Panel Bottom" are held together by the jacks mounted in the panel. These holes are about 30mm and fit the semi-standard 28-30mm panel mounted components. The included components include a automotive 12v jack, a 2x 5v USB with volate meter, and a switch to switch those on and off. These were bought as a set from Amazon and used pretty much as is except without the provided mounting panel. I also included a Anderson PowerPole jack which is required for my radio activities. This is a standard APP connector in a 3D printed house. I will make this available someday in the future. I don't use anything to secure the top. When it is closed the lid should be pressing against the panel and battery cover. When it is open it is a light friction fit. I would appreciate any feedback. Slack - N5TAN
