Short in my mech

[Bonyai]

I made a mistake by tightening my pt3 with a aero airflow controller to my galileo mech. I know it shorted cause my mech got hot and the firing button got hot. Took out thw battery and it was hot as well. Is the battery unsafe to use now? Cause I put on my aerotank and it fired fine. The coils werent shorted both the coils on the aero and the pt3 read 2 ohms.

I put the tank in all the way down on the top part of the mech before putting the mech together to push down the pin. Always did it this way this is the first time I got a short. Not completely sure why. Im just kinda scared this thing might blow.

I know Im such a newbie. Any help and suggestions would be greatly appreciated.

Greetings; It's a good thing that you dealt with the problem before the battery went totally unstable. I had something similar happen to me recently.

I'm pretty new when it comes to mechs, so i'm going to let someone else talk about whether the battery is still safe to use. No harm in being cautious and seeking out some good advice.

Thanks Glenn. Im currently swapping out tanks and both are firing fine on the same battery. But still scared so I stopped. Thinking of going to my local shop to pick up a new 18650.

same thing just happened to me, ironically wit the same tank, on my nemesis.

I'm intrigued aswell to see what they said, although I got my battery out pretty fast and it didnt get too hot. maybe a little warm at best

I wouldn't use a battery that had been severely shorted to the point of being extremely hot.

Mine got kinda hot miles. I felt the top and bottom of the batt and it was kinda hot

how about a IMR hybrid cell that has no physical deformations, didnt get hot, but defintiely very warm, and after resting the battery for 30+ min showed about 0.03v drop from the incident?

Why take a chance? Just toss it and get a new one.

True Ill just get a new battery. Any ideas to what may have costed the short? I do the same thing everytime and I dont understand why it shorted this time.

The battery has been damaged. Honestly I'm not sure on the exact risks, but batteries are cheap enough to replace. Plus, you don't know what shorted out, it could be the battery failing internally.

The cell already has been replaced by a MNKE 18650.

However, I can confirm its not a internal short for several reasons;

1: the hard short ended once the tank was removed.
2: the mod itself was hotter than the battery inside. dunno bout you, but running 8+ amps through stainless steel tends to heat it up. at least in my experience it does
3: the cell has shown no signs of overheating under a controlled discharge (Slow discharge might I add) to 3.5v, AND to a full charge back to 4.18v

now dont get me wrong, unless someone has a VERY good reason for me to keep my panasonic cell, its getting taped and taken to lowes tomorrow. but I'm just trying to understand, if the battery is behaving and the hard short was not severe, should I really be worried?

btw, the battery in question is inside 3 metal tins in a busted brinks fire safe (dont ask) which si inside my garage. I'm pretty confident it'll be ok for the night.

Hey topacka how does a batt short internally?

My SVD with a dripper on it gets pretty dang hot, I never paid it no mind, the battery is cold due to its air holes

lithium batteries inside have a coiled metal grid/plate structure. during extreme heat or stress (IE, dropping it or hard shorting) the plates can touch one another and cause what is refered ot as meltdown. the reaction continues inside the battery until it either vents violently or even bursts into flames. worst case is explosion.... in your face.... literally.

thtas my logic behind the incident. the mod was very warm, but the battery was barely warm.

when you over tightened your atomizer, you bent the wires creating a short, once a battery has been stressed and has pushed more amps then it is capable of, it is no longer safe to use it, no matter what ohms your atomizer is. The chemistry inside the battery has changed when it overheated and pushed more amps then it could. It is no longer the same battery, it is now a unknown factor with unknown characteristics and very unstable. It is a grenade with the pin pulled. Time to toss it and duck and cover.

My batt got hot though as i felt it in the firing button. I might just pick up a new one tomorrow

That sounds wise, small price to pay for your face, and mod to stay healthy

Just got new batteries and ended up getting a kayfun ehpro clone. Running it on 1.2 ohms and loving it lots of flavor even without the airflow control screw.

I still haven't even took a vape off a kayfun

Batteries are cheap, as others have said, don't chance it.
Not worth it to me.
