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.
I’m not a flashlight or vape guy. Many cells have built in protection circuits. I always assume these are not present and make sure external protections are provided. Your idea should work, but usually smaller batteries mean smaller capacity, and sometimes lower current charging and discharging.
Do not solder directly to any battery. Have an explosive containment pie-dish nearby. Use under supervision the first few times.
I have a metal paint can, an ABC extinguisher and short term + long term disability insurance. I’m ready to do some stupid shit.
Hahahahaha, my kind of idiot (that is, I see myself in you)! 🤣
