Exploding battery

[Robert B]

A friend of mine got home from work, grabbed his nemesis (clone) mod with a plume veil on top, sat down to watch the news. Presses the button to have a vape and nothing happened. He pressed the button again, and heard a hiss. Opened his hand to look at the mod, and it exploded. It blew the fire button off the mod and blew the atty off the top at the same time. The battery shot out landed in the corner of the room and proceeded to burn a big hole in the carpet. He got a towel and grabbed the battery and tossed the thing outside.

The atty embedded into the drywall, and by looking at the trajectory, he said it missed his wife's head by inches, as she was sitting next to him.

I questioned him about the mod such as, "did the fire button stick"? no. I asked several questions about the atty itself. Then I asked him what kind of battery was he using. He said, "I don't know, maybe one of these"? He had a mod with a kayfun on top. I pulled the battery out of that, and it was a TrustFire battery.

He had tossed everything in the trash, and I asked him to dig all the stuff back out so I could have a look at it. This happened a week ago. If I can get a hold of the blown up parts, I will post picts.

So far, the moral of the story, and the cliche that may ring true is, don't buy batteries for vaping that have the word "fire" in the name.

Buy high quality batteries, also buy a high quality charger, not some 4 dollar piece of shit. If you can't afford those two things, or your a cheapskate, you probably shouldn't be vaping. just my opinion, take it or leave it

I wouldn't use a '---fire' battery in a flashlight. Glad nobody got hurt.

 

[Robert B]

Yeah, I kind of worry about people being suckered into buying the chinese fakes, and the ramifications it could have on the vape industry as far as regulation goes. The chinese certainly don't care. They make their money in the short term, and go on to rape, pillage & destroy the next big industry.

Don't get me wrong, there are many chinese companies that do care about the long term, and sincerely try and build a quality product. But sadly it seems most don't.

 

[Jon@LiionWholesale]

Wow, glad your friend is alright. I absolutely agree never buy a ultrafire/trustfire battery. You never know what's in it since that's not a brand that means anything at all, there are lots of companies making batteries with that name. Which also means no repercussions to the manufacturer if something happens.

 

[BigNasty]

Dude.
Friend's do not let friends vape a mech with shit batteries... just saying.
Time to educate the wife on his dumb ways and hammer battery safety home to your buddy.

 

[MrScaryZ]

Yeah I could see this happening almost no venting on some nemesis enought pressure build up boom...
wowzy I cant imagine trying to explain to the police that I killed my wife with a Atty and it is stuck in her head
jesus

Trust me, I hammered battery safety home to him... diplomatically of course !!

 

[BigNasty]

LOL, but with the wife nagging him after being nearly getting an atty facial, he might get it.

 

[Number3124]

Seriously. If there's fire in the name or on the wrap *coughefestcough* don't buy it!

 

[MKPM]

None of that happened. Would love to see pics of the stripped out threading on the stainless atty and the stainless top cap on the mod.

 

[Robert B]

He said it scared the living shit out of him. Not only was he lucky his wife wasn't injured, he was lucky to only get a mild burn on the palm of his hand. He said it sounded like a gun going off inside the house.

Hopefully I can get the parts to look at

 

[UncleRJ]

I am glad your friend was not hurt.

Sadly, folks are not going to be aware of which batteries are good and which ones are trust/ultrafire quality unless they do their research Or get good batteries and advice from a local shop with knowledgeable folks behind the counter or have a knowledgeable friend that is looking out for them.

 

[BoomStick]

None of that happened. Would love to see pics of the stripped out threading on the stainless atty and the stainless top cap on the mod.

I'd like to see pics also, but the nemesis tubes can be had in aluminum. Not sure about all the top caps. Maybe it was crappy, soft metal.

 

[MrScaryZ]

What we need to have happen is get better batteries we have been stuck on Li-ion forever now all I know I have never had any of the top name brand batteries blow but have had them vent and its not pretty... It takes alot to blow the name brand ones in fact I have tried to and failed so far

I have almost nuked a vtc 4 but it was stable enough to hold out without venting long enough to break contact.

I remember when on ECF that stacked mod blow out took the dude's front teeth out.
Then later on another forum robert almost blew his balls off with his garage made mode misfired.

 

[Robert B]

I guess it's no secret, so for anyone who doubts the story, it happened to Gary, who worked at Killer Juice in Bay City Mi. You can call Walt (owner), and verify it if you wish. I talked to Walt today who said he thought he still had a picture of the battery and the hole burned in the carpet. Said he would text it to me if he could find it. I have not been able to get in touch with Gary yet to see if he saved the parts or not.

Haha a garage made mod well yep.. I vented the vc5 in the Cana mod it all caught on fire no blow I tried to blow one s few weeks ago with a .025 build and a Samsung 25 r it just got real hot then fizzed like a shook up coke that was it I just put the mod in the driveway and let her go ... Garage mod Baaad!

No it is not a name brand it is a sworn promise of that the hell is going to happen.

 

[battery bro]

I visited Trusfire's battery assembly plant in Shenzhen earlier this year. They actually have a decent operation and don't normally use 'Grade C' cells. They very openly rewrap cells and exaggerate the specs - that is their #1 strategy. So you get new cells however the specifications are usually way off and dangerous for modders. They cater mostly to flashlights which doesn't matter as much.

The other problem with Trusfire is trademarking. Ultrafire and Trustfire have bad trademark issues that have still not been resolved, so it opens the door for counterfeiters to come in with little repercussion. And then you get things like Grade C cells entering the mix.

Bottom-line is don't trust the fire brands. Buy authentic, as rewraps are impossible to qualify their integrity.

At the entrance to their assembly lines

A look inside. The line on the left is focused on 18650 batteries.

He is spot welding PCBs to their wires. These limit their battery to 6A so are only meant for flashlights.

Hope this is interesting

So you're saying that Efest batteries are shit? I started using the purple Efest batteries a few months ago, & have had no problems.

 

[battery bro]

If it's their 30A it's because it is a rewrapped LG HE2 which is rated for 20A. You should be fine, but it is a 'lower quality' HE2 and should only be safely discharged at 20A. Exceeding this and using it like a 30A+ will severely limit your batt's cycle life.

It's their 2500 mAH 35 amp purple. I just bought a handmade unreg. mech box, 18650, will those be ok to use in it? All of my coils will never go below .4, so I believe I should be ok. And I have Samsung INR 25R 18650 30 amps for backup, but I have read too, that those are re-wrapped HE2's also. What about finding some HE4's? Maybe those are better? Or maybe I should just grab a few MXJO batteries and be done with it.

 

[Number3124]

Treat them like 20As. They'll be fine.

 

[Daniel]

I'm grateful for the help...Thank you kind sir.....

 

[battery bro]

MXJO are also just rewrapped LG or other cells. MXJO cloned Efest - they are basically the same thing. Yes - just treat them as 20As. If they get very hot while discharging, you are asking for too much current.

 

[tcmx250]

Wow. I had no clue these were dangeous. Checked ratings and reviews before purchasing. This is the first I've heard. I have 4 ultra fire 26650 7200mah and a nitecore i4 charger. Had em for almost a year now, not one issue. Running an onyx mod, plume veil rda, and a dual coil parallel build @.019 ohms. Should I be concerned?

 

[tcmx250]

< is pacing around staring at his batteries nervously...

 

[Rommel]

Never trust a Trustfire, thats a common saying in the Finnish vapescene.

The 35 amp Efest batts are 20A continuous. So are the Samsung 25R and the LGHE2 and no the Samsungs are not HE2's in drag.

I would be.

I would almost give my right arm to find a true 35 amp battery. I saw almost, because I'm right handed, and can't do shit with my left...Well almost nothing...lol

xxxxFire batteries an a 0.019 build?!? How are you not already dead?

 

[tcmx250]

Again, thanks for the heads up, i will be dumping these and getting new...suggestions on what to upgrade to?

How is that even possible. Those batteries are ICR. They have PCBs. They shouldn't be able to supply more than 6amp at any time.

 

[OBDave]

Not too familiar with 26650s myself - I know Sony made a great option, but those seem to have gone the way of the dodo...honestly I'm not sure there's anything out there that can safely support 0.019 ohm. Any chance you might have moved the decimal by mistake?

Even then xxxxfire batteries are ICR. Their PCBs shouldn't even allow more than a 6amp draw before they blow.

 

[Zamazam]

The only battery I've had go bad on me was an ultrafire 18350, got really, really hot in a regulated mod I was using so I dumped i into sinkfull of water and let it fizzle and bubble. After that, every ultrafire and trustfire battery I had ended up in the battery recycling can at work.

There's always a chance, as I am prone to mistakes. I'm guessing the meter I used is wrong, due to the comments posted above reguarding the battery and allowable current. I'm guessing the thing that's saved me is the onyx mod has good battery venting and that I am not drawing more than 5 seconds at a time?

No. The decimal point has to be in the wrong place. If you really did have a 0.019ohm build it would be drawing 221amps. It is physically impossible to run that on an IMR battery let alone an ICR. Forget pulse ratings. That's flat out impossible to make with Kanthal. The only material I can think of that will make that resistance is 30ga Nickel at 2 wraps with an ID of 2mm. However, at that resistance you've dead-shorted everything. There's a mistake somewhere. Perhaps you meant 1.9 ohms?

 

[Robert B]

According to Stephen at GenuineCells, the HE4 have the same specs as the HE2's, except they were designed for Bosch cordless power tool battery packs, and supposedly better at handling heat. I have a pair of them and they act, charge and discharge seemingly the same as the HE2, Sam25r's, and VTC5's I rotate through. Usually run everything between .4 and .9ohms

Again I apologize, I am not trying to be an idiot here. Most likely .19. I'm pretty sure it was sub ohm I'll check it again when I get back to the shop (helping a guy with a startup vape store). I am new to the sub ohm builds, please be patient with my dumb ass, but I am eager to learn.

That would be more feasible. It would draw around 22 amps, but there's no way an xxxxfire battery could do that without blowing the PCB.

 

[CaFF]

The only Trustfire batts I have are the old TF "Flames" 16340s for my Buzz Pro, and one remaining purple metalflake protected "2000mAh" 18650.

They are genuine ones I got in Dec of 2012 and still do very well.

Ancient photo:

That purple battery is the longest 18650 I have...it has stuff on BOTH ends...kinda ridiculous really.

This: http://www.dx.com/p/trustfire-18650...tomatic-protection-battery-blue-purple-149967

Features:
PCB protected board
With overcharge and over discharge protection plate (!)

None of which, ever have seen anywhere near sub-ohms.

If you make quad coils, 5/4 wraps of 18 gauge Nichrome N60 with a 1.5mm ID, you can hit 0.018Ω easy You'll definitely need to drill out your post holes, but it's possible And you can safely pull 221A (at 4.2v) with 8x 18650's in parallel. That's only 928.42 watts of power flowing to your face

I'm glad you took that in jest opposed to being serious. I had hoped I conveyed the sarcasm adequately.

In all seriousness, though, 8x 30A batteries would, in theory as it applies to Ohm's Law, be safe to run builds that low. I don't think I'd ever do it; that'd be a helluva hot vape. But I would be interested to see the results of someone brave enough to try. Heck, I'd even build it for them

With proper air-flow it would be nice and cool. It would basically be a pair of posts holding up a driptip at this point, but that's enough airflow. Cloud chasing like a champ!

For those of you who doubt a stainless steel mod can explode, check this. Probably a hybrid style mod with an atlantis, is a recipe for disaster. Looks like it might be a stainless 4nine. Sounds exactly like what happened to Gary with his nemisis and shitFire batteries
