Spotted this today while searching for ways to make a Makita battery fit Ryobi tools.
That's kinda neat.... sorta cool to see a way to breath new life into old tools.
my own little mod..... surprisingly easy, little cutting, little soldering. Battery fits amazingly well. Just an FYI this thing always sounded like butt for music though works great for audio books and talk radio
I modified my Dewalt DC983 14.4V nicad drill for running a Dewalt 20V max pack.
It's been running pretty well.
I don't have a lot of pictures from the conversion:
