Fwiw, I've started test fitting of few lights in my battery tests.
Is there a proper designation for a protected 26650?
Any recommendations for an unusually slim cell of that size?
(I got an otherwise decent flashlight in the mail, and it’s bored out so it takes those 18650 plastic sleeves.
My EVVA 26650s would almost fit the tube but I’m sure it would scrape off the shrinkwrap and maybe the protection circuit if I pushed it in.)
