I wouldn't do it because you have no headroom for safety.
Everyone is free to set their own safety parameters, and I can only say what mine are.
I try to never exceed 50% of the CDR of a battery. So with a 30A battery, that would be 15A.
This Ohm's Law Calculator tells me that a .28 ohm build is as low as I would want to use.
The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades. As the mAh degrades so does the batteries c rating. (amp limit) So down the road, your 30A battery may only be a 15A battery.

I agree with Susan. Don't push your batteries. They can become very dangerous in a mechanical mod.

You could, maybe for a period of time, get lucky enough to not experience any issues. You're actually lucky, in this case, because the Panzer experiences a decent bit of voltage drop, so your battery might not vent only because of voltage being lost through the mod itself. Essentially, voltage drop will be saving your life. As a side note, the Panzer is a very metallic/dense mod. A violent discharge in a Panzer, I'd imagine, would result in a LOT of bits of shrapnel. It'd probably be on par with a military hand grenade.
The lowest ohms you can go on a 20A battery is .22 ohms. At this point, you're knocking on the door of the 20A limit and saying, "please don't hurt me." My recommendation is allowing a good 5-10A of headroom.
Additionally, when did you get your VTC5? Sony hasn't been producing VTC5's for nearly a year now, and the vast majority of VTC5's sold are actually just VTC4's or LG HE2's (or another battery with a 20A limit). A good rule of thumb is to just bank on your battery being a rewrap/20A, because 30A+ cell technologies seem very scarce, and when batteries DO get released with these advertised limits they're usually sold out super quickly, and in their place you find a bunch of re-wrapped 20A batteries.
In short, no. Don't do it.
I'm not judging so don't take it that way
I love mechs and that's all I use but I'm curious as to why you want to go this low?

1. Because everyone at the vape shop super sub-ohms. Why shouldn't I?
2. I read about it on ECF. I'm curious.
3. My buddy vapes a 0.15 ohm dripper.
4. For the clouds, man. For the clouds.
5. Because I want to be cool.
Lol@ bad
Its funny too. As much as I don't care for the guy I love rip showing how its done single coil around 25- 30 watts. Room filling storm clouds once you know how to properly tune your setup.
He runs a magma at 17 watts and puts out like a fire extinguisher. every sub ohmer should watch that vid
( you know you want one)

Agreed, I'm in love with my 14-wrap .6 ohm dual coil build (even a fat-... single coil works great too). Given very rudimentary tweaking/wicking techniques and a regulated device, my .6 ohm will stomp any <.2 ohm build on a mech mod. And I'll be doing it demanding FAR less out of my battery.
There are other reviewers (PBusardo in specific, Igetcha69 too to a degree) who will build 1 ohm builds and chuck HUGE clouds, as big as you could possibly want. In the end, I think the need to go "super low sub ohm" is a fulfillment of an entertainment thing. I don't know what you're vaping for, but I personally started doing it to LOWER my chances of harming myself. Putting myself at risk for something else just seems entirely counter-productive to "quitting for my health".
In the end though, you're gonna do whatever you're gonna do. People are just like that, as much as you can tell them that something they're doing is unsafe, they're going to see a need to do that thing -- a "need" that many of us on here just don't understand. There are plenty of people who are safely sub-ohming. In my perspective, "safely" sub ohming means keeping it above .4, and ideally, using a regulated device with some form of protection to, at the very least, keep your safe chemistry batteries (which you know the limits for) from violently discharging.
That will be 28 amps @ 110 watts. Heck of a lot of power coming out that little battery
That scared me. Have fun

No.
That is already over your amp limit. No headroom for safety.
Build higher than .3 ohms.
No. Don't build that low. Ever. There is no need to go that low regardless of Mod. Look. Maybe Nothing will happen. Maybe you will be fine. But you could die. Or become like two face, from Batman. Or like Gus fring from breaking bad. Worth the risk?
The only head room in that build is the room between Your jaw and the rest of your head.

Seriously? By asking this question it reveals you don't get it yet.
You know the amp limit of your battery (continuous, NOT pulse). You know how to measure the resistance of your coil, so therefore you can figure out how many amps that coil will pull from the battery. YET, you ask if you'll have safety headroom with that setup.
Learn the Ohm's Law principles before you attempt any coil rebuilding.
1) Know the continuous discharge amp limit of your battery. Don't exceed it.
2) Know how many amps your coil build will pull from your battery. Use an Ohm's Law Calculator.
3) Measure EVERY coil you build prior to firing it. Don't take for granted that so many wraps will equal so many ohms of resistance, there are too many other variables.

Baditude, brother. I'm sure you know from first hand experience... But I deal with this every single day. Every. Single. Day. Sometimes I just want to facepalm myself into nonexistence. I find that my patience and eagerness comes from people honestly trying to quit smoking. They're typically middle-to-older-age smokers. But then the dudebros come in, hopping around like monkeys, asking questions about how to "chuck clouds" that "hit like a freight train", but neither listening to nor comprehending answers. I find my patience for them becoming thinner and thinner on a daily basis. I usually preface schpiels with, "Are you currently a smoker?" and when I get the, "Nah, man," I have to swallow a lump in my throat.

On the contrary, I'd rather people come to ECF to run their silly ideas by us before they go ahead and do it on their own. I pretty much solely hang around the New Members Forum just to advocate safety/help out the new guys.
I really don't wanna see someone hurt themselves, and ruin it for the rest of us.
I get it, Rocket. Remember, I worked in a vape shop, too. With the types of customers who you describe (dudebros), I found that I had to sit them down at a demo table and explain exactly what was going on with a sub-ohm setup and why it was potentially dangerous. I told them how I had a battery explode in one of my mech mods, and I wasn't even sub-ohming at the time (the mech fire button auto-fired). Sometimes I got through to them ... sometimes not. But I did what I felt was ethically responsible for the customer's safety and well being.
Not everyone in this vape shop did what I practiced. Many of the shop's employees were right out of high school and or college age, and knew nothing about the differences and specs of batteries available for vaping, and the sales staff usually came to me if they had a battery question after finding out I knew something about them. If interested, I printed out my Battery Basics for Mods blog to use as a reference. What more could I do?
This shop had a policy of not building sub-ohm coils for customers, but would watch a customer build one and allow them to use the stores ohm reader. They encouraged cloud chasing and had competitions in store. They saw this as a business opportunity.

You can lead a horse to water, but you can't make him use IMR safe chemistry batteries.
Interestingly, I had issues with the variety of batteries being sold in our vape shop (as well as others).
There were ICR batteries being sold as well as IMR and IMR/hybrid batteries. Not every sales person in the shop knew if a particular battery was safe for certain applications or not. Eventually they learned to come to me for advice, but I was only in the shop 2 or 3 days a week.
I recall having a casual conversation with a customer at the e-juice bar. He was a new vaper, sporting a mech mod with a RBA setup which I didn't recognize. I asked him what his build was and he said what do you mean.? I asked what ohm was the coils. He didn't know, he didn't own an ohm reader. Out of curiosity I measured it on the shop's meter. It was 0.15 ohm or so. So then I asked to see his battery. It was a pink Samsung ICR battery (rated at only 4 amps continuous discharge, way underpowered for a 0.15 build).
So, I told him to not fire that mod unless he bought a different battery or his battery could go into thermal runaway, vent hot gas in his hand or face, and possibly explode the mod. He needed a high amp, safe chemistry IMR battery. He bought a Sony VTC battery. Although safer than he was using, I explained that he still needed to build a higher resistance coil, and to buy an ohm reader to measure it.
IMHO, ICR batteries have no business to be sold in a vape shop. They are potentially dangerous for our applications.
To be honest, I'm thankful for the iStick 30 watt and the Atlantis (and to a slightly lesser extent, the Melo). It has made things so much easier when the kiddos come in wanting to blow clouds.
Typically (but not always), they're kids (a kid is 18+ to me) using an eGo battery and a common clearo. But they've got a buddy or two who are chasing clouds with a more advanced set-up, so they come in completely ignorant (not their fault) and want what their buddies have. There are typically two ways I can handle this: going into the very in-depth explanation of mech mods, battery safety, research, understanding Ohm's law, learning an equation, buying extra necessities like an Ohm reader or a multimeter. Proper, safe batteries. Kanthal and all its different gauges. Organic cotton. Ceramic tweezers. Coil jigs or a mini screwdriver set. And typically there are two ways they respond: with complete enthusiasm, or total eyes-glassed-over "lost you a looong time ago" blank stare.
9 times out of 10, it's the former, not the latter. Then I have to switch gears and appeal to base and willful ignorance. "Or you can buy this thing here (points to a 30 watt iStick), buy that tank there (points to the more affordable Melo), put juice in it, then vape and blow clouds."
They almost always choose that option.

When my sister told me her boyfriend got a "vape pen" and that it blew "huge clouds" I was very worried that he'd present me with some fancy pre-built RDA/Mech Mod combo. Was VERY pleasantly surprised when he had a Sigelei + an Atlantis because I know he's not the type of "kid" (he's 18-20 range) to bother learning battery safety/ohm's law/etc
