These are unstable, relatively short lasting batteries. I'm not against them, but it will take some time before they will be safe enough.
Again...Google it...I heard about single cell blowing up (releasing gases) first clue - cell phones...
We aren't talking about cell phones, we are talking about single cell 18650 flashlights in which the cells explode. You are making wild claims you can't back up. This does no one any good.
The fact remains that quality protected 18650 cells are quite safe when used properly, and there is no evidence at all of a single 18650 cell exploding in a flashlight.
