So I had an efest 18350 battery in my pocket, just to have an extra battery on me. Well, I also ha change in my pocket. All of a sudden I feel my leg getting really REALLY hot, so I dug through my pocket and threw the battery across the rooms because it was SO got and I was afraid it was going to blow up on me. I guess the coins created and completed a circuit with the battery inside my pocket! Scary stuff man. So, if you're gonna carry batteries in your pocket make sure there's no change, or metal for that matter, that can touch the battery.
Happy and safe vaping!
