Metal Detector hack/upgrade to run on shop tool lithium batteries.

This is another video showing me messing around with metal detectors. More mods to the White's Spectra V3i. Since I"m an occasional detectorist at best....I decided it would be nice to have it always ready to go....not having to plan ahead the day before and get batteries charged. I want to be able to grab a lipo shop tool and or a hobby lipo battery and take off. This is the process of making that happen. Also, I got tired of having to unzip the cover and pop open the plastic latches each time I wanted to put in a charged battery.
Bonus....I also make a super strong hand digger for detecting. Thanks for watching!
