I describe the various features I incorporated in my charging station. It was designed for my LiPo batteries for RC airplanes and can charge all sorts of other devices a well. It is portable... sort of. It's quite heavy. It runs primarily off AC power in my garage but has a 32 amp/hr battery for field charging of smaller batteries. I shot this video just after hooking up all the electronics and running a couple batteries for a test charge. I have a number of finishing details planned but it works and that was exciting.
