Rig Mod Explodes

[HauntedMyst]

Some times when I am building for my local cloud comps, if I can't get my mod to fire, I'll warm up the mod with my lighter (warm batteries fire better) and I'll bang the atty down on the tube against something hard to make sure I get a good connection. Did they do that? The guys always tell me not to do that because the battery could explode but they are just sissies. Besides, I always carry 8 to 10 M80's in my pocket just in case that does happen. If I am going out, I am going out with a BANG. I keep fake ISIS propaganda in my pocket so they get blamed. I hate those guys.

Explain 'half-wrap'...does this mean that only half of the battery was wrapped?
If this is the case, there's your culprit. If there's no barrier between the battery body and the inside of the tube, it will most definitely cayuse a short and explode.

Only if you're a fool and put the battery in upside-down. Otherwise, it will simply auto-fire (not an ideal situation, but not as bad as a dead short either.)

...of course, in the picture it looks like the mod vented from the bottom, which means that the battery was foolishly installed upside down, so what you suggest is not entirely out of the question.

I suspect the mod began auto firing as soon as the employee installed the battery, not when the button was pushed. It would have failed eventually, whether the employee was holding it and pressing the button or not. The reason: combination of the hybrid connector and the atty, where the center pin didn't extend beyond the 510 threads.
Just my theory.

Pinless top caps don't cause auto-fires, they cause shorts. They cause shorts when the switch is activated or the circuit otherwise becomes closed. Torn battery jackets bypass the switch and close the circuit, causing auto-fires. Put the two together and you have a bad situation, auto-firing on a short circuit. But it can still happen with an intact battery jacket, as soon as the switch is closed. Which is when this incident occurred. Hmm...

...a torn jacket and upside-down installation will also cause a dead short, and also not until the switch is activated, so I'm guessing that this was a case of either 1) pinless cap paired with a mismatched atomizer, or 2) a damaged battery with improper installation. In either case, it's user error, and likely has nothing to do with the risky-but-not-totally-unheard-of 0.17 resistance.

The threads bled out on the bottom from the pressure (thin copper threads) whereas the top was thicker (so I'm told)

The employee doing it I have never seen install a battery upside down, and (I wasn't there) from what witnesses told me the battery also shot out.

Also, if the Rig is a hybrid cap, the firing pin on the atomizer MUST protrude past the threading by AT LEAST 5/16" to minimize possibility of shorts.

Do you perhaps mean 1/16"? 5/16 is over a quarter-inch, or nearly 8mm. That's almost the width of a drip tip. I mean, the center pin needs to stick out a little bit, but not that much. 2 or 3mm should be plenty enough, I would think. On the couple of atties I just measured, the whole 510 connection is not even 5/16" long, let alone the amount by which the center pins protrude...

Actually, the Rig is a true hybrid. Not a pinless mod like a SMPL. I know, I use one daily.

Only if you use a hybrid atty. the rig V2 comes with a screw in hybrid style topcap. functionally the same as the SMPL if using a standard 510 atty.
The rig V1 had a top center pin.

...oh but in OP he did say it was a Rig/Roughneck combo. And the Roughneck is a true-hybrid atty, I believe. Guess I missed that the first time around (pics all showed the pinless cap when I searched for "rig mod".) Yeah I'ma go with torn jacket paired with upside-down installation, on this one. Caused a short circuit as soon as the switch was closed.

I have same the mod.
The top hybrid threads are thin.
The bottom switch has the button threaded through a solid coooer shoulder
The only logical way for it to happen was the scenario where a user installed the battery upside down and the wrap was damaged.
Instant short. Swollen battery top vented as usual, but installed uoside down.

User error.

Oh ya, bring on the Molly.................

Outside opinion - This makes no since:

near instantaneously(a few seconds without firing while he was checking for the coil to heat up)

Not firing while checking for coil to heat up????

Now, either it Blew up while Firing to heat the coils..................or
It Blew up while Not firing and letting the coils cool down.

Personally I think it would be hard to Determine - After the fact - Which error caused the failure.
Possible Defective Battery?
Possible Defective device(switch assembly)
Possible collapsed center pin(RDA Quality)

....and if anyone thinks a Melted/soft center pin grommet cannot cause a short

This could have directly come from NOT troubleshooting the original request before inserting another <CHARGED> battery.

customer in the shop asks an employee for help. His mod won't fire.

Ultimately - User Error

You wanna blow clouds and live on the edge, this is sometimes what you get.
No sympathy for anyone who WANTS to live on the edge if they fall off the edge.
Me I will just keep on vaping on at 12-20 watts.

"I've got a noisy cricket and it keeps getting hot! It was fine until I loaned it to a friend and a buddy of his built a new coil on it?" Yeah, I've no clue what happened here.
I worried about this years ago and it just seems to be coming true, unfortunately. I guess it's just human nature to push things to the limits.
Either way, it's a bad deal all the way around. I hope the employee recovers alright.

Mech mods are not "idiot proof".

When it comes to advanced mass-marketed systems like cell phones, laptops, and hybrid electric cars, the system designers of those products have taken appropriate steps to make them "safe" for uninformed end-user use. Purely mechanical unregulated battery mods and uninformed end-users is a dicey proposition.

Most consumer battery operated devices are no where near the limit of the battery's operating limits. The high-end flashlights, remote control toys, and e-cigarettes come to mind as applications that can really push the limits of a battery. With the RC toys the device is physically far removed from the person so a mishap is inconsequential. With e-cigs a mishap is literally in the persons face.

And even they have issues sometimes that cause the batteries to burn

But yes, they are a lot safer than mech mods and eGo style batteries.

So True!
If the industry ever built anything Idiot Proof - some couple would just have an improved Idiot to balance reality Oh wait...........we are already doing that.

I'm still wondering what made this Employee think he was Qualified to correct a defect?

If I have an Mechanical mod, ANY of my collection, act up - I take the battery OUT.
I get my Multi-meter and start testing. I Get answers, not assumptions and once I know what IS wrong, I fix it. Then I re-test it to be sure it is FIXED. Then I carefully test it with a fresh battery.

No Exceptions - ever.

This mess reminds me of all the Qualified Mechanics I have seen over the years. Oh, I fixed your problem................it was just a blown fuse!
WHAT?????
Okay, what caused the Fuse to Blow to start with???
No idea but it seems fine now.

Genius, just Genius

Speaking of RC cars, I was talking to a friend the other night about the new series mods and we got into batteries. He was explaining how serious the RC guys are about them. He was telling me the guys that really know what they are doing will trash the battery in the car (whatever it may be) once it's been wrecked. They just no longer trust them anymore.
Those batteries are a LOT more money than an 18650, but they don't take chances.

I'm guessing they do not own high end cycle chargers that can analyses individual cell condition?
I Fly electric RC and have never had a damaged Battery...........even in a plane totaling crash.

it seems to me things are extremely biased...
yup, if one is careless with something and it goes wrong, all of a sudden there is an outcry to ban such practice...

if thats the case then why are skateboards, bikes ( MX style) snowboards etc not banned...
a good faceplant will take out several teeth, an extended arm can end up with bones protruding thru the skin, a wrong step off of a skateboard can perminentally take out a knee or hip, a backwards fall off of a bike can put one in a hospital with a coma/concussion or even a fractured skull...

lots of people do skateboards, biking,snowboarding... and alot of people vape...
if you want top push things to the edge ( in any activity) then be prepared to fall off the edge....

I'm wondering what qualified the owner of the mod to be in a cloud competition when he's not competent enough to diagnose his own rig.

Should have been an instant disqualification.

Your mod doesn't fire? Better luck next time.

What is a "half wrap" battery?
Who used this term?

We dont have enough information to determine what happened yet.

Does mxjo rewrap any Batts that aren't imr/inr chemistry?

How would that protect anyone that didn't recognize a dead short?
