This last weekend I had some friends over, and let a buddy borrow one of my mechs with a .5 ohm build on it for the night. Cell inside was AW IMR 18650 2000mAh, so 10 amp limit. Build was drawing ~8 amps. Closer than I prefer, but my MNKEs were all drained except for the one I was using, and I was still within the continuous discharge limit.
After.... many... drinks we are all pretty intoxicated, and my buddy goes to take a vape and tells me the device is very hot. Hands it to me, nearly too hot to hold on to comfortably. I immediately assumed I was dealing with a thermal runaway situation and unscrewed the tubes, but the battery inside actually felt cooler than the mod. No venting, check battery voltage, 3.6v so it didn't even get drained that much.
Evidently he forgot the lock the button before laying the mod on the couch, and the device auto fired. Not sure how long it was firing for, but long enough to heat the mod up something fierce. It's an EMI Avenger V3, very low resistance, and doesn't even get hot after chainvaping deep sub-ohm builds, so it must have been firing for awhile. The majority of the heat might possibly have come from the atty too, not sure.
Want to know the biggest surprise of this whole situation? .5 ohm build, COTTON wick, after extended auto firing cotton was just ever so slightly darkened. That shocked me quite a bit, I assume without airflow none of the juice was leaving the chamber (and it was partly wedged under his leg, how he didn't notice the heat I don't know (probably alcohol
) so it kept the cotton from straight up burning.
That's it, I just figured I'd show a story of an accident going right for a change When vaping sub-ohm setups on mechs USE GOOD batteries, and your accidents end with having to recharge your battery instead of a skin graft.
Things I learned:
I should keep an eagle eye on drunk friends with my equipment.
My confidence in good batteries was not misplaced
Cotton is surprisingly tough!

) Button down on a mech for a good 5-7 minutes of continuous firing.
