Glad everything didnt turn out worse, @wizardofozone. Could it have been the shock of the mod hitting the floor vented the batterys?

I asume it was the cause optic but I have less of an idea since even the battery switch functions and the hot glue they use on the top never even melted ...

It uses 3 18650 batteries in parallel.

Glad you are OK. That was a close call and I am delighted you skated it. I don't know much about that specific mod, save it's reputation, but if the case itself carries one side of the battery current-- likely, negative-- then you might have gotten a short from the impact if some live component from the other battery side contacted the casing. Just a guess. If it were me, I'd be terrified of it in the future.

I guess I love this thing too much .. The best I'd do I think is just buy another one as it really stops the endless search for me for something 'better' ... The 180 S is of course just reletive to my own needed passions with vaping. And in fairness, I don't know any product that makes sure of safety by slamming it against the floor ,lol !

For all three battery's to pop that fast and all at once there must have been an internal dead short in the wiring. I would not use that box until it is completely taken apart and the spot of the short is found. With that much current there is most certainly a scorch mark somewhere on the positive and negative legs heading to the control board.

Maybe a Provari? o_O

Why Provari?



There's an ECF member who used to intentially drop his Provari at arm's length onto a concrete floor just to watch people's reaction. The Provari could take it and ask for more. Sometimes the top cap will will pop off. Wanna know how to put it back on? Hit it with a wooden board and hammer.

    I might be seeing things, but those battery contacts seem to be able to touch both the positive "cap" of a battery and the can at the same time if the battery is pressed hard against the "+" contact (bending the center contact metal piece back). A fall could certainly do this and, if it did, could short all three batteries.

    I think that a lot would depend on the paper/plastic insulating "donut" being used (at the positive end), and the condition of the wrap, but to me those appear to be incredibly dangerous battery contacts to use.

    Yes there must have been a short.

    The most likely point would be a spot corresponding to the main positive input to the electronics; it would have touched most likely the aluminum body as a result of the impact.

    Yep that's what I'm seeing to.
    Would be worthwhile to insulate the inside of the battery cover.

    I would start looking here
    View attachment 478310

    Please tell me there's an insulator between that connector and the body
    Boden, your pic is showing a green circuit board so that's an 180 the 180S has a blue circuit board and they must have seen that and changed the bottom contacts which are about 1/8 inch above the body base. the top contacts rest below 1/8 strip of foam rubber attached to the bottom of the plastic 2 screw cover at the top after you remove the wolf face back of the unit. as a side note, after the fiasco the first thing I did was check the contacts and all were in normal position , plus the new 18650's went in as tight as usual.
