12 v Battery Box with Charger & Battery Booster
Radios / April 8, 2016

I wanted to build a fully integrated, portable, 12 V battery box for portable operations like Field Day.  When I found these Ridgid cases at Home Depot, I thought they were a convenient size, well built, looked great and were a reasonable price.  I also noticed there are clips on the sides that allows you to stack the boxes and lock them in place.  It occurred to me that I could build up a set of modular radio cases and easily stack them up and snap them together.  One case for the radio, one for power, another for accessories or whatever.  A lot of Go Kits include radios, accessories and batteries all in one case, like a 19″ rack case.  While these look great when they are set up, the big problem is weight and bulk.  They are very heavy and hard to move around.  I prefer to have smaller cases that are easy to carry and also provide of some degree of modularity.  If you want a different radio, for example, you can still use the same battery box.       Having one box with the battery system on the bottom and the radio in a second box…
