This happened just last night. Before bed last night, I decided to check the forums and email. My wife already was asleep. I decided to load up my dripper and vape while browsing. I put in a freshly charged battery. I was running a .2 ohm build in an older Efest 1600 V1 (rewrapped sony VTC3). I took a few puffs as I tried to load the website.... the internet was down, so I locked the mod, and went to the router to check things out.... After working with the router for about 5 minutes, I realized, I wasn't getting a signal from the internet provider.... so, I sat down to do some maintenance.... Through the light of the computer monitor, I saw some vapor coming from the drip tip..... the mod was NOT locked, and it was continuously firing for 5+ minutes. I went to pick it up, and it was too hot to pickup, so I turned it on the side so it would stop firing..... I grabbed a towel, and took it into the bathroom put it in the sink and turned on the water.... It sizzled when the water hit the mod. After a few seconds, I unscrewed the bottom button and took the battery out.
The mod cooled down battery stayed in the water for a bit. It was so hot, it started to split the shrink wrapping (it continued to shrink it until it split). The mod was fine, battery was fine... no bulging, smell, etc. I still might not use the battery just in case. turned out, I had not locked the bottom ring.
So, continued advice... do not vape a pulse rating, always vape continuous rating and use safe batteries.
