Some of this stuff is esoteric and frankly, hard. I don't vape but I love to read about flashlights and batteries. I was very confident after years of reading this forum that a bucket of sand was best for thermal runaway. Just yesterday I learned that water is the recommended method to prevent spreading the fire and insertion in sand may exacerbate heat build up and encourage flame. Some here would still argue sand is best. Years ago we were told to ALWAYS and ONLY use protected batteries. Now many argue unprotected batteries are safer. We were told imr batteries have "safe chemistry". I've had posters tell me there is no such thing as an imr battery and they are all hybrids now. My point is that even a dedicated reader can be baffled by all the conflicting info. I must admit, however, that every source I've seen says to stay away from *****fire batteries. Ironically, I used a safefire 17670 battery in a Quark ti because AW wouldn't fit and a dealer I respect recommended it. Never had a problem with it but recycled it for more modern 16650 battery just because despite years of safe service it was a safefire.
