    He was using a "skeleton key" mech mod with an Atlantis 2 on top. Don't know the build or the type of battery. I would assume he was running stock coils (~.3 ohm), so most likely he had a crappy battery in there or somehow had a short somewhere.

    Does it use a hybrid top cap? That's caused all sorts of problems before.

    Poor guy, whatever went wrong went wrong in a big way. A violently venting battery would only result in an explosion if the mod did not have vent holes. Perhaps the battery was of some other chemistry. There does not appear to be a wrapper on the cell. The message of the article was pretty clear, this is what e-cigs do.

    ......happening more and more over the last year

    In the last month, three e-cigarette smokers in Southern California have been stunned when their vapor cigarettes blew up. Some think the problem may have something to do with the battery. One Santa Ana e-cig smoker is lucky his exploding cigarette didn't kill him.

    Good point. And a terrifying warning to us all.

    While venting can be quite gentle, an ICR battery can have an astoundingly violent reaction in thermal runaway. Even an INR or IMR, though ICR is almost always much worse. With the battery constrained by the mod tube, and the top cap held on by the action of pressing the battery up against the top of the mech, I can see the pressure building up to a very high level. It only takes holding back the pressure for a fraction of a second for the pressure to rise very high. Think firecracker laying on the ground versus a firecracker in a closed fist. In a short circuit, a battery can reach the thermal runaway threshold temperature before the vent can reduce the pressure. If this happens...boom.

    All conjecture though...

    I know they said the battery swelled so fast it closed off the vents and jammed the guy from getting the cap/bottom off on the one that exploded at the vape blast, seriously it can happen so fast it is over before you know what happened.

    Of course. But the article did not get into specifics, which is what I meant about the message they were putting out.
    Fox News again. Although they interviewed the victim, they didn't address why it happened.
    They told the Who, What, When, Where but not the Why. That's bad journalism.
