All thoughts on this occurrence welcome as I would prefer it never happen again Been vaping over six years and just had my first "what the hell" moment with a mod that was just sitting for a week (not touched). Fan of the Noisy Crickets...own five V1's and one V2. Four of the V1's have the Fatdaddy upgrade kit and the fifth had an Indestructible RDA on top. The only one without the Fat Daddy kit (the one with the Indestructale RDA ) has been used sparingly as a flavor alternative without issue for over six months with Samsung 25R's and had been sitting, hardly used, with relatively fresh Samsung 25R's (4/17/17 start use date after full charge) on my desk for about a week. Fortunately I was at my desk when, for no apparent reason, heard the hissing and was able to remove the indestructible and batteries to prevent further issues. I am of the thought that it was just a defective battery (one came out hot and blackened 2/3 on the negative end...the other was not unusually warm and appeared fine). Throwing both out, but wanted to post here to make sure I'm not missing something. A bit unnerving to think that if I was not at my desk at the time things could have been much worse, even though I try like hell to vape safely. A mod just sitting around for a week untouched with freshly charged new(ish) batteries shouldn't be an issue right? Had to be a defective 25R? Thoughts? Will start loosening the rda's on the mods I occasionally use as flavor changers. Thanks!
