To greatly reduce the chance of a mishap, only use authentic name brands cells with a sufficient CDR to support the power range you intend to use.
Only buy cells from reputable well known sources.

One of the main points of using a regulated power device is the several layers of protection features.
If you stay away from the low quality devices having one or more of the protection features fail is very rare.

usually the cause of a battery venting
using a battery that isn't rated for your vaping needs, causing strain and over working the battery
using a damaged battery, dents, ripped wrapping
leaving your vape in your car where the temp in the car gets extremely hot
carrying a lose battery around not in a battery box

@bombastinator et al who have Aegis 100W. Does yours have a funky odor? I was reading about how you can switch out the insert after removing the skeleton and that the glue used to keep the insert in place smells. Lol, I thought that maybe the guy who sold it to me had aftershave on his hands when he packed it....until I read that article. Silicone does have a way of holding odors. My question is will it ever go away?

It’s not a question of whether a device has vent holes or not, it’s a question of does a device have adequate vent holes to cover all or the majority of venting situations. And if a battery enters a state of venting, how far off is it from thermal runaway? There are many YT videos that display these batteries going from venting to thermal runaway so quickly that one does not even have time to react.

Personally I think the vent holes with a lot of these devices are nothing more than a sugar pill…they are in place to falsely ease the conscience of the consumer. There is no way to predict how a battery is going to vent, and what the pressures are going to be.

If you have concerns about battery venting, get a device that has magnetic battery doors and don’t push your batteries to a point where venting becomes a higher risk.

I personally think the door will still go before the gasket does. That vent gas needs to be like 600f+ to melt silicone and I don’t know if it is or not.
Iirc, there is a sharp bur that will puncture the silicone layer under pressure, thus allowing the gasses to escape.

Looked to me like foam glue under the USB port. It’s dead hard and crispy now.
My sense of smell has never been great and I never noticed any odor from it when it was new. It’s probably “new car smell” level stuff. The things have a lot of polymers, and they’re goint to outgas for a bit after they’re manufactured.

If a battery goes road flare it doesn’t matter if it has magnetic battery doors or not. If it can vent it won’t explode. Gotta have a strong airtight casing to build the pressure for an explosion. A lithium fire is a lithium fire though. All you can do with a metal fire is throw the thing onto something non flammable and wait for it to be over. They burn really really hot and nothing puts them out.

I understand that if a battery goes road flare magnetic door will do nothing. I never stated anything of the such within my above comment.

So question. What is the venting pressure of a battery? You come up with that figure, which will not be static, and you should be able to calculate whether 5 small pin sized holes would be adequate enough to relieve that pressure.

Five pin hole sized holes and the mangled wreck of a USB port. The other factor is how strong is the containing case? In the case of the ageis 100, very. That vent might get quite a bit bigger before it’s done burning, and the flames shooting out of it might get kinda long though with all the stuff escaping through that one hole. This is why I personally think the bottom door on the legend will probably just blow open. It takes a metal fire not just a vent to do that though, and if you’ve got a metal fire you’re looking at a future pile of melted slag no matter what you’ve got, Be it a mod, or an electric car, or a WW2 nazi rocket plane. The only thing to do is get the hell away from it. Or it the hell away from you. Luckily mods are small enough to be thrown.

True but I bought this used from a friend. I should then assume that the outgassing has passed (no pun intended:rolleyes:). That leaves the possibility of aftershave. I'm too embarrassed to ask him. Now I'll be smelling every aftershave at the pharmacy to track down the odor. It's driving me bananas!

Tried washing it? It is waterproof

Bottom line is;
If you select an authentic name brand cell bought from a known reputable vendor/dealer with a sufficient CDR to support the power range you intend to use and use it in a quality regulated power device, it is as 'safe' as vaping gets.

If you pay even the slightest attention while vaping the very first warning sign will be heat.
Warm - okay,, hot - never okay, stop vaping remove cell to cool.

If you use quality components and use 24 brain cells while vaping the chance of battery venting / thermal runaway inside a decent regulated device is almost nonexistent.

There is no metallic lithium in a lithium-ion battery. What burns in a thermal runaway is the electrolyte, which is a lithium salt in an organic solvent.
