I think perhaps your inquiries would be better suited in an electronics based forum.
Nothing good can come from attempting to repurpose the devices that are used for vaping, and I personally believe it's a fool's errand to attempt to do so, unless you are an engineer with the credentials to back it up. In which case, you're still in the wrong forum for such matters.
Please try to keep any further such contributions on target. (I'm no mod, nor rules nut, but you're stretching the bounds, and in a way that could present very negative consequences if such was attempted)
