Reusing vape batteries in flash lights? Is this a crazy idea. (lemmy.world)

So people throw out disposable vapes all the time. I cracked one open to take a look and it turns out they have a 18500 battery in it. So I was thinking of 3D printing a spacer to make it the same size as a 18650 and putting some shrink wrap on them. I just wanted to see what people who know more than me think. Is this a bad idea that is going to burn my house down? a waste of time perhaps?

I did a trial run in my wurkkos fc11 and they seem to work, it charges and looks just as bright.

Rubbish. Many high performance flashlights won’t even work properly with protected cells, they need more amps and trip the protection. Unprotected cells are perfectly fine providing you use a proper charger and don’t short circuit them. That is assuming you use good quality cells, I would not trust what is in a disposable vape.
