I received a new trident clone yesterday and decided to try it out. Dual coil reading .8 ohms and I throw it on my k100 to see how it vapes. Push the button and get nothing. I fiddle around and push it again, still nothing. I did notice the lower section of the k100 was warmer than normal so I take the whole thing apart. I have MNKE 18650s in there and have never had an issue. But the one I remove has overheated. The vinyl wrap is melted down towards the bottom on the side. I let the battery cool down. I then re-wrapped the battery and tried it again(I know this is not a smart thing to do). I guess the whole battery just shorted out because it will now not do anything. I'll drop it into the recycle bin at Home depot and get a couple more batteries. But what could cause one to go like that? These are only a few months old and I have never dropped them or abused them in any way.
