Very interesting. Maybe I can afford Milwaukee tools now! Their tools are good, and sold bare, for semi-reasonable prices but their batteries are eye-wateringly expensive.

(I should probably pick one of these up before Torque Test Channel does a video on them and they end up getting sold out for a year.)

Edit: I'm referring to the PDNation universal battery + brand-specific adapter in particular.

Just took a look here, and I didn't see anything over 20V offered. I'm in the market for 40V versions for some of my gear.

I also have Gold mount and V-mount type batteries that I'd love to have the cells replaced. If you think power tool batteries are expensive, take a look at film/video batteries!
