I was playing 2k and was vaping, and I sat down my vape next to me. Two minutes later I grab it about to vape it, and I hear something burning and it smelled really bad. At this moment I was freaking out that I sat the mod down on the floor waited like a min then I opened mod and then I took batteries out. I smelled the battery slot and it smelled bad, then took off rda and the 510 smelled bad. I didn't wanna vape it so I just left it like that. The mod is IPV4 with Sony vtc4 with mutation x v3. Anyone know what it might be? Thanks
