The nuclear meltdown is when the cells in the battery fuse together. Most batteries can handle a hard short for at least a couple seconds before venting occurs. Venting is the end result not an explosion as long as your mod is vented correctly.
Interesting point. Consider that pic of the IMR battery spilling its guts that looks like an accordian.

Due to the extreme heat of venting hot gas, some batteries will swell beyond their original proportions during thermal runaway. This swelling could easily block off the vent hole and any escape of gas, allowing a further buildup of extreme pressure within the metal tube. This could result in what quite literally would be a pipe bomb.

That's why I said as long as your mod is vented correctly. I doubt anyone knows if their mod is correctly vented. These YouTube reviewers get a mod free of charge from the manufacturer, and they only talk about how it performs and how it looks. Then they keep it and consider it payment for their time. If its free blow it up, cause that's the only info we have to know.

Exactly Bad, Exactly.

Venting a battery and dismissing it as oops... my bad, is risky. Yep, it may be just a burst of hot gas... or not.

That happening while driving, well, that would suck. I can think of many places that a venting battery would suck.

When people are trying to go extreme sub ohm, It is a whole new set of risks that many vapers seem to just dismiss offhand as no big deal.

Yeah... That kinda gets back to the "Blind Trust" thing I mentioned Earlier.

People pick up a Mod and there is a 3mm Hole in the End Cap and they Feel Safe. I mean it's Vented.... Right?

But then I look at Picture of Batteries that went China Syndrome and it seems that Many of them did it from the Positive End of the Battery. And Many of them Were Swollen Up like a Prom Night Pimple.

And the Venting Occurred when the Pressed In Carto/Clearo Connector Popped Off like a Champaign Cork.

It is the nature of the beast. People will push the 18650 as far as they can go to get every drop of power out of it. Once the 22650's become more popular there is going to be a bigger problem since those already have 50 amp ratings now. People won't take the time to do the research and take others word. Then take my word, keep em cool.

Definitely always be aware for heat as that's your first sign. Keep tabs on the heat. When your doing 3-600 cycles of high amp drain a day anything could just all the sudden happen... We all just want people to be safe, for one our way of vaping depends on it. People get burned up and well be regulated into submission...

I've never heard of someone needing 35w to get off cigarettes. How big are the clouds with smokes, not huge. You could just get some higher mg or some different juice if your not satisfied.. You can adjust your coil distance from the intake, different coil different wick, different atty. an atty can make a big difference. There's other ways to get TH.. With that said I know people that do 30w just make sure you know how to be safe about it.

It's a very good practice to try stay below 60% of the batteries amp rating on a mech. The reason the battery drops in voltage output is due to the heavy amp load and in no way should that figure be used to calculate your amp draw. 4.2v should always be used.

I wonder how much energy a 35 amp battery would expel in a vent, I'm guessing a lot more than a 10amp.

Live long vape safe

I started with cleros, and cartos and it wasn't enough, then tried Genesis and just got too a point I wanted more. That punch in the chest feeling is what I crave from smokes, so that's where the high power comes in.

Sorry if you Already have posted it... But what mg level did you use when you Tried to Switch to e-Cigarettes? And what mg do you use Now?

Also for me what I'm in search for right now is the good nic that has a mean th. It was around in the beginning and now it's all gone to wussy clean clear nic good for fruity vapes. I think its garbage. Weak th... Upping my mg with this nic helps but then it's way too much nic for me I'd rather have a nic that packs a serious punch at my tolerable nic level, like it used to. I think the weak nic pushes many of us to subohm to try to get that punch.

so far as I can find xtream vaping has the best th nic along with maybe stormys by her discription. Not sure who she sources from and never tried it.

From beginning to first break in order, 36,24,18,12,6,12 break 24,6,0,6. Considering 12 now and raising my ohms from .36 to around .5 and switching to the 26650 mod n battery. I go through a lot of juice, and get a lot of heat, so looking to get out of both.

Gotcha.

Everyone is Different. But Many have Found what they are Looking for by Raising their Nicotine Level Slightly.

I've been having my Sony vtc5's getting hot. Lowest build I've used longer than a day was 0.28ohms.. now I'm back up to 0.45+ohms.

I have 5 of these batteries.. it seems like most of them get rather warm under ~10Amp loads. The funny thing is, the only one that I know doesn't ever get warm is one that I fired under a dead short with 4nine mod+Atomizer pin being too short for hybrid contact on battery.

I've read that Sony's get warm under 20Amp loads, and I've seen several tests for them.. never seen any IR images of them under different loads though.

I wonder if you hooked up an inline volt meter if you are getting lower voltage under load. If you are, it could indicate cell damage, and if it does heat up again, it could just keep heating up till it vents. I would rather push a battery that acts like the others, than try anything hard on it. If I can predict heat, then I can prepare for heat.
