Yeah, show us 4 year old pictures of mods that had stacked battery's in them that are charred.
If you can find me a picture if an exploded VTC in a mod, I'll quit posting for good. It ain't gonna happen.
Sub ohm battery chart vtc5?

Any battery can explode, let's say you put a great battery in a housing (mod) with no venting the mod accumulates pressure inside the housing, eventually if little or nothing gets out it becomes a small bomb of sorts and bad things happen. The battery isn't always the reason mods blow up, that said even the BEST of batteries go thermal. Sometimes even the hardware isn't to blame in fact it's usually user error.
The pictures I had in mind weren't stacked, but I don't know if the battery was a VTC or not. ...If you'll notice, my post was in the form of a question not a statement. I don't know what pressures are involved so I don't know if a venting VTC would blow apart a mod or not. I do find myself skeptical as to the functionality of a couple of holes on the bottom of a mod with a expanding battery going through thermal runaway inside.

Getting back to the OP's original question... I found this chart which expands a little bit more on a previous post. As long as the OP stays around his .18 sub ohm build he should be pretty safe with a VTC5 30amp discharge rate, IMO. Although battery life and performance will be affected over a long period of time.

Here's a pic of an AW 18490 IMR battery (15C rating = 16.5 amp continuous) which went into thermal runaway. Notice that the inner works expanded out from the outer cell casing as it vented. Imagine this happening inside a metal tube mod and blocking off any vent holes that may be in the mod for protection. Rare, but it could happen, and I wouldn't want it happening in my mod.

I've seen this picture so many times now that i will start dreaming about it.
Na but seriously it's great that you keep posting in every other thread!
To many new and/or ignorant people that goes into deep waters.

And that is exactly the reason that I continue posting the pic. We have new members joining every day which may not have seen the earlier posts or pic. Too often we take for granted that the batteries we use in our mods are safe and don't even think about a dramatic venting incident.
The last pic below happens to be the battery that exploded in my own mod, so the potential for danger is forever ingrained in my mind.

Geez. I was only asking to educate myself not to scare people. I have friends who easily run under .9 ohms with VTC5 batteries. All I was searching for was more info as to how low you can safely go so I stay above that limit at all times. I'm not a ..... who wants to build .02 ohm builds or lower without any knowledge or whatever. I've done tons of research I was only looking for a definitive answer. Thanks for the input thus far guys but let's keep discussion to my original question and not off topic posts warning me about sub ohming. I understand the risks involved and understand how to mitigate or remove those risks.

Not being rude, but exactly what do you need? You know the Sony VTC5 has a 30 amp continuous discharge rate limit. You know how to use an Ohm's Law Calculator to confirm what amp a particular resistance coil will pull from that battery. What's to know beyond that?
I already figured it out, I guess I was asking about the pulse limit and a few fellow sub ohming friends gave me feedback on another medium. I just felt the responses were advising me to not to sub ohm lower as opposed to helping me do it safely which is all I asked.
Nobody here is going to give advice as to how hard you want to run into pulse ratings.
The sony is good for a coil below .2ohms.
If you have equipment good enough to measure accurately down to that, and know ohms laws, you can make your own judgement about how far past the safe constant current ratings you want to run your battery.
The knowing ohms law part and measuring with real equipment is important as every tenth of an ohm at that low of resistance is multiplying your amp draw exponentially.
No way I am putting a a.05 ohm super nanodragonclaptonbutterfly coil and a 30 amp battery together with my teeth tho

All this talk about pulse ratings; what those suggesting that it's ok to go by that number never discuss is how long a pause there needs to be between pulses. For example, if one pulses with a couple of seconds in between it's effectively continuous discharge. I believe that dampfakkus uses 30 sec pauses when pulse-testing. What vaper is going to take at least 30 seconds between puffs, each and every time?
