Mech mod just started firing *results - RBA Build*

[Joka]

So I almost caught fire to my bag. Which contained my new $800 cell phone, and other various things that would have been detrimental to lose. The mod was a caravela with a patriot clone. Dual coil with cotton. It WAS locked during the incident. I looked over and stacks of smoke were coming from my bag, so I unzipped it quick knowing a mod was firing, and it was inside of a small bag. So when I yanked it out it melted my finger tips! It took everything I had to disable it quickly before it blew the battery or caught actual flame. It was so hot I couldn't touch it for maybe 30 minutes, and i spit on it. Instant boil and evaporation for like 20 mins. My patriot looks to be ruined to me. A post actually got so hot it leaned, burnt the whole center pin out. And baked my drip tip so it taste horrible to vape. Is there a way I can fix this center pin? It's brand new =[ I'm also including a picture of what I can if it helps. This was actually really scary, I'm just happy it wasn't my new kayfun with the clear body...

That's one of the reasons i'm not entirely fond of the idea of getting a mech mod :O

How did you turn it off if you couldn't touch it in 20 minutes?
Scary indeed... Glad you found out before it actually catched fire.

Where is the popcorn smiley?

I don't think this would of happened if you had used an IMR type battery which this isn't. It is a protected type with a very low amp levels and not high drain. Without knowing what the RDA ohm was it is hard to say but these batteries are not suited to sub ohm vaping.

AW IMR which are the most common are not protected, and this would still happen(I dont even know that ive seen a protected IMR). They only dont explode violently like li ion do, which didnt happen here, but they are safer for that reason. Also IMR batteries tend to have a very high AMP limit making them great for lower ohm builds on mech mods. The only thing that would stop this is a kick with a cutoff when it comes to a mech (or making sure your device is locked and safe to use obviously)


As for the OP, do you know why it was firing? If you have a problem with the mod and it was firing without the button pressed, i would contact the vendor and ask for a refund or replacement immediately. That is extremely dangerous and unless you know the cause and are 100% sure you can prevent it in the future I wouldnt put a battery or atomizer on that mod if you paid me


Edit: I searched and there are protected IMRs, which i never knew, but ive also never seen someone using them as compared to the countless unprotected AW IMR users!~

I imagine that this happened because the negative end of the battery came in contact with the UNINSULATED BUTTON HOUSING on the Caravela clone. Maybe the battery wrap was damaged? That's the only reason I can think of for this type if thing. People, please inspect your batteries regularly, just to be safe.

 

[ianryeng]

From the pics you posted im guessing its your patriot that was to blame - looks like a short between the body and the centre post.

Agreed that IMR wouldnt have helped.

Very glad to hear you caught it in time - a fuse might be a good addition to prevent this in the future.

I'm going by the picture which isn't an IMR battery it is the NCR1860B with specs Test / Review: Panasonic NCR18650B 3400mAh (Green) | BudgetLightForum.com. Now I'm not aware of a protected IMR battery but see there is one based on your note above.

I also would guess it is the atomizer shorted also.

The battery touching the base around the firing button was kinda my guess. The center pin looks horrible but I think it was just the baked insulator. I'm going to try to clean it up...is there any way it will work the same again? New insulation and center pin? So should I modify my caravela to stop this from happening again...?

I would try to get a refund / get it replaced if it's possible.

Seems like shoddy craftsmanship... Dang man that stinks.

At least everyone is safe. Good luck in getting it fixed!

 

[Funk Dracula]

Well now...

That looks like some thick wire for the coils... at least 26g? Dual coil eh? That looks like, at the highest, a .5Ω dual, but I'm guessing it's closer to .3Ω right?

That Panny is fine for a mech running a single coil Kayfun, keeping your resistance 1Ω and higher. But nooooooo.....

Sir... from the pics... it appears that you are absolutely doing it wrong. Flying in the face of reasonable safety guidelines offered and pushed here at ECF; all courtesy of convenience, trends, and Fasttech eh?

Also, that's not the first Patriot clone that has melted with sub-ohm vaping either.

YOU ARE SO FREAKING LUCKY THAT DIDN'T BLOW UP IN YOUR BAG.

You had a sub-ohm coil circuit constantly discharging the battery, that's bad... and HOT... BUT do you realize how freaking explosive that was about to get when the post of your Patriot clone melts all the way, causing a hard short that won't stop????

If you had a VTC4 or AW 1600mAh battery in there, it could of fired a .3Ω atty until the battery discharged and died, or the coil popped. If the Patriot insulation melted all the way, causing a hard short, it would of gotten hot like your panny just did.


Now that I'm finished scolding you... I really am glad your okay.

If your mech was locked, something shorted in the switch and completed the circuit. Most definitely in the switch. I haven't seen a Caravela switch taken apart, but from the looks of it there's no derilin. I'm sure someone who owns one can/will chime in.

Besides everything that is wrong with your rig by your poor decisions, the switch of your Caravela is what happened to have gone south for you today. (thankfully)

 

[^Top-Shelf^]

I would not recommend using a panisonic in a caravela because the lack of insulation around the negative side. In the caravela there is no insulating piece for battery to sit on. I definetky wouldn't recommend using the battery you were using because it is not rated for high amps.

 

[Muggs]

Wow man glad you are ok. I had something similar happen to me with a Sigelei 20 roller clone and a .8 coil. The button spring split and seized to the tube. Constantly firing just like yours. Burned or should I say melted a mark in my finger from thre bottom cap being so hot.

I have an EHPro Caravela. What version do you have?

 

[certus11]

The upside is: you won't be so startled/shocked the next time around. That's very positive because if it happens to someone else, and you happen to be around, you would be able to remain calm while helping them (or not).

 

[Tugg n chase]

I have the ehpro also, and the negative end comes unscrewed occasionally. I can see how it could have appeared locked from the outside but loose on the inside causing a constant fire situation

 

[Joka]

My coil is 26g and .8 ohms actually. I actually don't fret on the scolding, I'm listening to advise instead taking it hurtful. Thanks for the comments and such guys! Neither of these can be returned but can I purchase only a base for my patriot?

Need to check out the mod and see how it closed the circuit.

Battery, right or wrong should not have caused this. - It should not have been sending power anywhere.
Even if Patriot was shorted it should not have caused this. - it should have had no power on the coils.

Check your firing pin height.
Check the Battery Wrap for damage on the Negative end(switch end)
Does the Caravela have a Delron spacer on the switch for the battery to rest on? Some mods dangerously leave this out.

Hah, i read your post wrong somehow, and im not even sure how. I need to get tested for dyslexia =( Looks like a failure of the mod tho, yes, and oddly enough that battery somehow held up. Very lucky of the OP that didnt burst, because it would have been a heck of a lot worse!


I bought a roller clone that had a hard short in the switch somehow, i simply put a battery in and suddenly i see a wisp of smoke and glowing red around the switch, with no atty on. Very scary experience. If i couldnt have returned it id have just tossed it and bought another. Plenty of solid clones out there to be had cheap
