First of all, the process of making 18650 is a "messy" one, and to make safe cell, there shouldn't be any metal contaminants - well known issue...
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...
