Battery & Mod Explosions

[Wraith504]

Ok so im sure everyone hears the horror stories about things blowing up. Now i want peoples opinion and experiences. As far as things blowing up goes. Said battery is put in a mech mod that has vent holes...the battery decides to teach said noob a lesson for running a .000001 coil build without checking resistance in a feeble attempt to look cool blowing clouds at a high school party. Battery goes thermal. Now according to physics the expansion needs to be compressed to create the explosion i think. (I THINK). Is the battery casing itself acting as the compression on the chemical expansion and heat inside the battery or is the mech? A pipe bomb has to be sealed to explode or else one of the end caps of the pipe will shoot off with no big boom because of the lack of compression. What are your thoughts?

batteries swell and block vent holes. Most mods don't have adequate vent holes. Now you have a pipe bomb.

I think the mod would be pretty friggin hot that you would have tossed it before it blows your phalanges off.

A battery hitting thermal runaway can go BOOM! in a matter of a split second - or maybe it might take all of two seconds tops. You hardly have time to contemplate your navel and think up a logical exit strategy for what to do with a venting mod/battery.

Throw it like you pulled the pin on a grenade?? LoL

You mean like the guy at Vape Blast did? Not something to lol at people could have easily been hurt.

I am guessing. I wonder if he was using a home made mod or not??

No it was a clone. BUT He did make some modifications that fubared the venting.

 

[Wraith504]

No it was a clone.

i see.. do we know what kind of battery it was?

Human instinct is to try and stop things from going boom.
I've spoken to a guy who had one going thermal and tried to take the cap off to remove the battery. Luckily it didn't go boom but he was wearing gauze and tape as gloves for a month.
Then there's the issue if the current sticking the mod to you. Not sure if that happens or not, but if you out a fork in a socket, the electricity traveling through you to get to ground will not let you remove the fork. Not sure if the high drain battery behaves the same.
Not ready to find our either.

What is yalls take on the CCI video of a battery being autofired on purpose with no insulator trying to purposely thermal it. and it simply just cut out?

 

[Mrs C]

Off hand I don't remember but the info on it is given in the reports on it on several posts on ECF and other places.

Thank you, ill look into it. Curious to know what battery it was.

Haven't seen it. I have seen quite a few that show one going thermal though. Personally I don't want to risk my fingers or face. I'll go with what is recognized as safe practices.

The. Battery boom heard round the world.

The battery might vent slowly, quickly or boom without warning. No two circumstances will be the same. There are too many variables to consider. Best case is it vents slowly. But even that would not be nice.

Ouch. I dreamt that the charger(!) for my pad went thermal the other night. I sure did a lot of stuff to prevent it from exploding.

I don't believe it will. Imagine that you lick your fingertips and put your right finger on the positive battery pole of a fully charged 18650, and the left finger on the negative battery pole. What would happen? This is the worst case scenario, as far as I understand.

I don't think thermal runaway causes the battery to pump out more volts. As far as I can tell from googling around, you need more than 40 volts, plus water, for electricity to be lethal.

Looks like that vid shows what happens when everything worked the way it should on a runaway. The battery vented at the top, you can see it off gas at the top of the mod, and see the residue on the atty. Where the problem comes in is when it doesn't vent properly. That's when things get very nasty very fast.

Being outside in cold with snow under the cardboard may have played into it to.
