Do Black and Decker batteries lack protection electronics?

Great video!
Would this modification to the drill stop the original batteries that came with the unit from working?

[raptorsuk]

But does it work the other way around?

[lonleystoner]

Does this work with the newer v20 version I would like to try and convert DeWalt batteries to work on my Stanley FatMax tools ??

Pretty MISLEADING, because you didn't really show how you must hack away part of the *TOOL* to get the large sloped end of the B&D battery to fix. I was watching, but not reading your silly "subtitles" at the bottom of the screen.
It doesn't help that you made the whole video in absolute silence before finally remembering to switch on the microphone when you tested the tool. It's so much better if you *SPEAK*... and then you don't need to edit to add all the subtitles. It also means you don't need to do all the silly hand gestures and finger-wiggling. Just talk, FFS.
