mods blowing up? Really?

[Baditude]

Where do you weigh in on the idea of using a charging bag?

Strictly my own opinion, but I'm against using them for our application.

The charging bags were created to put Lipo batteries (used for RC devices) in, while the actual charger remains "outside" of the bag. Our Li-ion chargers require the batteries to remain in the charger. IMO, the bags theoretically can trap heat generated by chargers, and actually cause more harm than good. Batteries do not like heat, and charging is when a battery is most vulnerable to vent. So these bags were not designed for our batteries or chargers. I'm a firm believer of using the correct applications for the task at hand.

If someone believes using these bags makes charging Li-ion batteries safer in their home, then that is their choice to make. I'm just not a fan of them for the above reason.

It's not possible. Lol. I don't spend any time trying to increase watts anyways. That's for the cool kids. I'm just enjoying being smoke and dip free. I get plenty of flavor and vapor with "low power" (by today's standards)

I have been in discussions regarding this topic, and I'm not sure where I lean when it comes to bigger batteries.
But I use charging bags religiously for my Ego Twists, which is all I use nowadays.

There just isn't enough heat being generated from charging an Ego Twist to justify NOT using a charging bag.
At least I feel secure that my house isn't going to burn down.


My current opinion is that if you are going to use a charging bag, don't buy a cheap piece of crap one.

I think this is very much an under-discussed topic here on this forum.
I wouldn't mind seeing a massive thread with people trying to dig to the bottom of this question someday.

Now that is what I would call innovation.

Not just a switch..button..shiney tube... or an LED that shows the weather/time/resist or answers my phone calls.

All I see now in vaping is the same as the government and money. Oh how do we make this better... awww shucks Biden just throw a few more Chase's at it or a couple Wilson's. In vaping it is just throw more wattage.

Absolutely! I think this is a great idea!

I've been playing around with an US vaporizer (from FT) and a nebulizer (from a yard sale). Not too much as of yet. The vaporizer seems weak and finicky. The nebulizer on the other hand seems to give an OK vape, but it's cold. Wanted to run it through a coil for heating/further vaporizing.

Another possibility is an old-fashioned atomizer (as in the thing you spray perfume with). Combine the atomizer plunger with a switch. ETA: Actually an atomizer uses a rubber bulb and the bernoulli principle, but perhaps just a spray-bottle might work, too

The nice thing about not using heat for the actual initial vaporization is that it greatly reduces the power you need, it doesn't backflow into your juice, and you should be able to control the amount of vapor in each puff to get a consistent experience.

One of my favorite vapes was using the wizard-stick - you could pool up a big thick cloud of vapor which was warm enough to be pleasant but not so hot it burned your lungs out. Shame they are so finicky, but they ran for a while on 6 AA batteries.

So I really do believe there are a number of possibilities for getting big, tasty clouds without going to high-current setups.

Sorry for going a bit OT, but it is relevant because a better technology would get the problem cut down significantly.

Call me crazy, but wasn't ultrasound something akin to the original e-cig design? The downfall being that e-liquid atomized in that manner is only room temp because it's not being heated.

Wouldn't getting a good vape out of 1 watt require the e-liquid to use an entirely different base? Something with a lower specific heat...

Out of curiosity, is there typically a warning period with it?
Someone mentioned batts can blow with any build. Could you literally be sitting there, and boom, or is there like.... a minute of noise or something. Some kinda warning?

 

[Kaezziel]

Typically it's gonna get hot before it pops....

*ETA*
This is due to the fact that battery failure is caused by an undesired chemical reaction within the battery... chemical reactions typically generate heat...
The amount of time before it does pop may be very short or you may have a "minute"... depends on many variables...

Which I guess doesn't help if you set your mod down.

Depends on the 'reasons' that the battery tips over.
Probably the most catastrophic is the battery that was over discharged or over charged. It can go off in the first millisecond of being activated.
Any model builder will tell you to stand behind a brick wall when charging those lipo cells after your plane crashed (hard thump).
Heat build up from high amp discharging gives a warning that is difficult to ignore in most cases.

The first sign is usually warmth or heat where normally there isn't any. The fire button or the mod body itself. The battery. Pressing the fire button and nothing happening is probably a short.

The thing about battery pulse vs continuous discharge rating builds -- if you have your build built to the continuous discharge rating, you'll likely have minutes to react because you'll have a margin of safety already built into the setup. If you have your build built to the pulse rating, you're already above battery spec and you'll only have seconds to react.

And how should one react? I mean once it gets going, it's a chemical reaction. Does throwing the battery in water stop the runaway? Or do you throw it outside and wait for it to stop? I know that probably sounds like a silly question but my inquisitive mind really wants to know. You seem to know all of the things I ask but if not then...

If the mod is not TOO hot, attempt to remove the battery from the mod and allow it to drop to the ground, preferably outdoors, or in a bucket or waste can. At least this may save the mod from exploding and will allow the battery to vent freely. I don't know about dropping it in water; I seem to remember reading something about that, but that could have been just been some internet bobbycock, too.

If the mod is too hot to touch, avoid burning yourself and just drop it to the ground and kick it to where it will not cause any harm to others in case it would explode. Keep a safe distance.

I'm open to hear other suggestions on this matter.

OK while you were answering, I found this..FAA Study on Extinguishing Thermal Runaway on Laptops

But water is probably all we would have to hand and apparently it was not the most efficient method although it does work.

So I like your method better!

 

[twgbonehead]

The only thing possibly bad about throwing it in water is that Lithium will react very strongly with water (and release a ton of hydrogen in the process).

Look at this idiot, for example (who peeled a battery for the lithium):

[Bassnorma]

Kinda makes you think huh Bad? If the FAA had to have a procedure for extinguishing laptop shipments (with batteries in a supposed stable state); then how much more care should we exert when using them for non-standard purposes.

Don't be too sure... https://www.youtube.com/watch?v=GUkqIWtOf-4

No, it didn't blow, but it sure could have. It's not about the mod exploding, but the battery.

From the looks of his eyes and his dazed reaction to the battery mishap I have to wonder what he was smoking before he vaped that super sub ohm coil. He was more worried about having to wash the battery gunk off the wall than the possibility that it could have changed the shape of his face.
