***Id suggest also adding an inline fuse between the battery terminal line, and the master switch. This will give some extra protection to this connection. I added a simple in line fuse a couple months after I built this box***
Heres how I made my 12v, portable power box. Equipped with 2, Hot System LED's, a 2 port high speed USB charger, a cigarette lighter port, a volt meter, and 2 charging posts. I used a 12v, 12ah battery, which will soon be swapped out to a 12v lithium battery. I walk through each step of the build. If you looking at building one, check out how I did it.
