1st thanks to The Puck for the AA batt mod ideas.
I took a 2AA and 4AA and made a puck mod with a led meter. I like the way it holds with the smaller 2nd case. I also made a battery bridge so you can use 3 or 4 AA batteries for a sort of a quickie variable voltage. I was originally making this a bottom feeder but could not fit everything into the 2AA case so that will be the next project with smaller switch.
