I wonder how easy it is to DIY something like that. Like would it be as easy as picking up an off the shelf power supply with the right voltage and current and 3D printing an attachment that fits into the battery slot with a DC jack on the side (or even just gutting a dead battery pack and taking out the batteries and control electronics, soldering a DC jack straight onto the main contacts, and drilling a hole for it to poke through)? Or do modern power tools actually need to authenticate the battery with some kind of tool DRM?

idk about modern tools but this totally works with an ancient Bosch drill I had, well at least the motor with speed controller from it
