I was using an Omega with AW IMR 18650 battery. The battery was less than a week old.
I did not have a multimeter, but I do now.
I have a Trustfire Multifunctional TR-001 (couple years old) and a Tenergy Multifunctional TN270 from PureSmoker (month old)....I'm not sure which one I used with the battery that vented.
I did post about it after it happened but only got a couple of responses.
I have been vaping for close to 3 years and never had a problem. After 2 reports in the last month of mods knocking teeth out...I am questioning everything.
