Saw a couple of YouTube videos and read a few forum post about using 18650 batteries in the battery compartment to boost the voltage, so I thought I would give it a try using the components of the box itself. The only thing I added was a engineered piece of plastic that used to be the cover for a jigsaw blade box. I'll send a picture of the voltage output once the batteries I bought are fully charged and the epoxy dries where I wore it a bit thin. I did test it with mostly charged batteries and was getting 16.04 volts. I was also able to channel it out enough that it is almost perfectly flat and the same dimensions prior to fabricating. Drops right in and falls right out just like a regular battery pack should.
