I had a misfire. My eRoll was charging in the PCC, 20 minutes later I went to the bathroom to stealth (doctors office) and I heard hissing in my purse! Pulled the battery out fast, my eRoll was hot! Burned up most of the juice, leaky mess. Swapped atties, new tank, waited a moment. Battery worked fine, but the burnt juice smell was gross! Vaped on that until I got home, pitched the battery. Now I keep my battery on charge until it is done, then flip it upside down in the case. I don't keep it unattended in my purse anymore!
Once is all it takes to change your habits. I freaked the day it happened to me. I have not intentionally left it charge side overnight a few times since, and it didnt appear to fire. It seems like its a freak occurance, and i really wonder what sets it off
