Li-Ion comes either protected or unprotected, if the description doesn't say your at the wrong vendor. IMR, CGR and NCR are still Li-Ion but use a different chemical make up, so instead of popping they will vent gas instead. The thread you posted is strictly user error, ALWAYS keep your
batteries so that a direct short can't happen. Any battery will do this when direct shorted, Alkaline, NiMn, NiCad, Li-Ion, even lead core batteries. Direct short means any non-resistance connection between the positive and negative terminals of the battery, like change in a pants pocket or purse, or metal cartos in a glasses case.
I always get my batteries from RTD Vapor and chargers too, I've been using Panasonic NCR18650's for about a year now, charging them in a NiteCore I2 Intellicharger without any problems. When I carry a spare battery with me I keep it in a small case with a 10ml bottle of
eliquid in a plastic bottle, no other metal objects are in it. An ego case works well also, it has pockets to keep everything separate. Just use a little common sense and you'll be fine, I've been using mods and these kind of batteries for three and a half years without any problems.
