Wow, this needs to be a sticky for sure. This is some of the best information that I've read on ECF!
My thoughts about sub-ohm and latest VV/VW devices...

Hey, if you mean yourself, I missed that post and had I known I would have been asking you questions about it
It just ... doesn't happen that way. I literally have not had a single dry or bad hit since I started using this technology, and I've tried all kinds of stuff. Hot spots don't randomly form that way. At this point you are basically just naysaying; from experience in my opinion this is transcendent technology. And why not, it's literally adding dimensions to its functionality that no other vaping technology operates in. The ability to respond to changing real-world conditions inside the atomizer simply did not exist in vaping until now.

Its taken me (for one) a damn long time to get to being satisfied with my vape; close to 5 years of daily tangling with gear.
I have and sure others too have thought that this industry is, or at least was ( a couple years ago) in its infancy... geez how its bloomed in numbers since '09.
I remember thinking - for sure some day, this is going to be a lot more user friendly, safe, and innovations are going to just take what sometimes feels so primitive (flash light form factor, and wrapping wires around ss mesh dunked in juice lol) up into the modern age, and mostly talking about atomizers as being in need of innovation... its electronic after all.
I was thinking along the lines of wick materials and coils at the time and how much effort and gear it takes to make (build) your atomizer... not like taking a cig out of a box lol.
This could be the start of consistent vapor satisfaction; right off the bat.
The 50- 100w mods have made all the stuff we use to do obsolete. All that work we did to reach a great vape with the technology is now no longer relevant, overall. Now with the DNA 40 temp control it's another jump in technology. With that I should be able to get 200-300 ml on one rayon wick and coil.
The temp control will be awesome. In a year or two when the price comes down I will jump on it. Luckily I know how to work with what I've got and get it vaping great.
Someone had concern that nickel wire was no res so it doesn't heat up. Well it does get hot as heck. I found that out in the past holding the no res to test fire a coil by touching it to +\-. Bunt my finger quick. Just recently in a discussion, in a thread that's even more ancient that 15w mods, you can see nickel glowing. The last 30 posts here are concerning 28-26g no res.

This is phenomenal that they have gone this temperature route. I imagine the chips are pretty sophisticated, and can detect resistance to the 100th probably. Controlling the temp by the resistance change of the nickel is really awesome. If it works out it changes everything!
P.s.
I think some of the confusion I had was possibly related to confusing it with The Peukert Law.. I see now that was based mainly on lead acid batteries and amp load. The lithium Ion's don't have the same characteristics.
At any rate now I'm seeing the full picture, thanks for filling in the blanks guys! I was only basing off my particular chips characteristics. And my findings were essentially mod specific only.

What's the battery life like? I'm intrigued but I've gotten so used to 26650s that actually last a reasonable portion of the day, and I'm predicting a long wait before we see this new tech in anything but an 18650 form factor.

Thanks for the link.
Just read entire thread.
Info overload.
Going now to take aspirin.
Very well written,btw.

I would conjecture that battery life will not be significantly different than we experience with w VV/VW currently. Even with the increased overhead of additional electronics, which will be in the milliamp or less range, being able to run at maximum efficiency should actually provide more battery life.
You have no idea what you're talking about. Voltage divided by resistance = current. Voltage multiplied by current =watts. Apply algebra and you get voltage squared divided by resistance = watts. Please review ohms law and the power formula.
water boils at 212 degrees F at sea level. PG at roughly 370 degrees F.And then comes the DNA40. You build a coil with NI200 wire just like you did with Kanthal. Only now you are in the .1 to .2 ohm range. You set your temp to 410 to 430 F a temp that most juices vaporize at. When you hit the fire button it pumps the total 9v on the coil to immediately heats it to just below the set temp. The chip then keeps that temp throughout your draw. Dry, wet, long draw, short draw, the temp stays constant and the watts jump all over the place keeping the temp constant. Been beta testing two units for 3 weeks. As far as I am concerned best vapor I have ever had and safest never a dry hit. Won't even burn the cotton dry. This is a new era.
at 430 degrees isn't one actually cooking the juice and creating unwanted
chemical reactions or does the amount of vapor produced temper any actual gas
that may be produced?

Batteries in parallel add up Mah, batteries in series add up volts. Higher Mah will generally last longer than higher voltage.

Agreed

You make me laugh. Please review how dc dc converters work. What you said applies to mechanicals only. With a vw vv device resistance does not affect anything related to how much current is withdrawn from the battery. Zero effect. Not even part of the formula.
Exactly. Watts In - Converter Losses = Watts Out.
Converter Losses are typically less than 10%.
You can apply Ohm's Law on either side to calculate voltage, current, or resistance from the other two, but you can't apply it across the converter.
Do you vape pure PG? Most people don't. And the boiling point of VG is around 550°F.
26650s don't make much sense in a regulated mod. Battery tech is most highly developed in the 18650 form factor, meaning you get the best performance to size & weight ratio in that form factor. This is why devices like like the VaporFlask and the BAP mod use dual 18650s, which give you more capacity than a 26650.
The recommended temperature setting of the new DNA 40 is 400-420 degrees. They said that the VG starts to break down around 500 degrees if I remember correctly. The device intrigues me and I am seriously considering building a mod around one. The stated price for modders according to the PBusardo vid with the dude from Evolv is 60 dollars. Recommended viewing by the way, very informative. Reasonable. By the time I fininshed an SX350 mod I had about $75 in the circuit boards alone.

Not true... I mean yes, in parallel the capacity adds and in series voltage adds. But it doesn't make one difference of you're running the same power. A 1000mAh battery will run 10amps for 6 minutes no matter what.
If you run a certain wattage at the 4.2 volts of a parallel set of 2 500mAh batteries and that wattage draws 10amps then the battery will last 6 minutes...
If you stack those same two batteries in series they are only 500mAh, but to draw that same exact wattage at double the voltage it will require half the amps, so you're only drawing 5 amps. Which means it'll still run for 6 minutes.
A regular will be more or less efficient at different voltages, so there can be variances, but you're only talking about small percentage of difference
$60 is "retail", quantity one. But there are these things on ECF (that only "Verified Members" can see) called "co-ops". They can save you substantial amounts on items like DNA boards.
