hey fellow vapers, I have been using this batteries for 3 weeks now and some time ago my mod got extremely hot dude to my rda shorting, this happen recently, I got skeptical and haven't use it since then. I recently looked at the batteries and notice the plastic on them is melted and I can see the expose metal, are this still safe for use? Should I travel to a volcano and toss this evil things before they kill us all?
