Well yeah ... I can see what the charts say about runtime. I'm just wondering if anyone did it and can comment on how they react to the power demands of the DNA20.
But I do have to say Eh? about the high drain 18650s. Which ones are you referring to? So far mine works fine and returns accurate voltage at 20 watts on even extremely low resistance loads.

I have only done testing with full HD 2000 AW and Efest batteries, and yes they work at 20 watts...but for how long IDK. I also didn't have any additional reverse polarity or fuse(s). Mamu has documented her experience using 18650's while testing for reverse polarity protection and the voltage sag at higher watt vaping was significant, even without the RP protection and fuses.
I try to save my round cells from the high wattage beatings and use my 6000mah 65c lipo.
~ how long are you getting on your 18650's at higher wattage? and what is the coil ohm and wattage setting?

I don't know how to express how long, I usually don't say hours or days since every day is different for me depending on what I am doing. But having run a 1200 mah lipo for a while, the life I am getting out of my NCR18650PD seems to be as expected for the increase in capacity. About double at low amps and maybe 3-4x at high amps.
On my initial test day I chopped on it pretty mercilessly at 20w for 6 hours straight with a .9-1.0 ohm coil before the battery gauge started showing empty. It was draining (small) bottle after bottle of random juices I had around. It probably would have vaped a while more since I notice 18650s can go a while on empty. I ran out of testing time and put a carto tank at 10w on it for the rest of the night and did not kill the battery (the gauge actually recovered to about half when i stopped beating on it).
Nowadays I vape 18-20w with relative impunity. Lately been doing an evod clone at 1-1.6 ohms. Battery life is great. I specifically chose this battery for its runtime to 3.2v under 5A drain. I have some LG batteries coming in which supposedly outlast it to 3.2v, I had missed that during my first order.
I am actually intending to start another thread on 18650s which I'm sort of surprised doesn't exist here yet. We ought to have some of our own testing going on, no? BTW that AW 2000 seems kind of like a turd battery, would only be for IMR safety but I think a Panasonic CGR18650CH would beat it out and remain safe.
To double back to the 18350 discussion, I am specifically interested in whether they can handle 20w vaping for any length of time. The Efest is supposedly rated at 8C/6.4A which is right at the border, and I have seen reports that the AW can handle high amps, but I'm wondering how well they handle that. Obviously this would be for a compact mod where battery life wouldn't be the #1 goal, and most people would not expect to last long vaping high watts on such a device, but I would like it to at least be possible to fire a DNA board fully with the battery used.

So I get an interesting effect with my battery, consistently. Last night after posting that, I went to bed, this morning the fuel gauge was still on empty. I continued to vape at 20w a bit this morning, then it finally threw a check battery message. So I lowered wattage to 13 and the battery gauge came back up about 3 bars. Now it's vaping fine again and I'll run it today and see how far I can go.
This has happened before, that the battery has "recovered" a bit when I lowered the wattage. What's up with that?

I'm thinking it meters at the time of the firing, maybe just a little after, then remembers that measurement for display until the next firing. So the battery will be depleted from the 20w firing and showed empty, but it actually recovers a bit after. Once you fire at 13w, it doesn't dip as much, so the reading appears to recover after the 13w firing even though it actually recovered after the 20w firing.
Nothing spectacular about that! The device is merely telling you it cannot receive the required voltage to provide the current required. Dropping the current requirement to its capable delivery setting alleviates the problem.
Ok so I'd estimate this efest 18350 would give you about ~2 hrs of fairly hard 20w vaping before dipping below board limit. Finishing out at 10-11w, will see how much more it has. Certainly a mid or low wattage mod but it appears it can do high wattage somewhat credibly for a while.
EDIT: Got about another hour of 11w. Now to test full charge 11w.

Battery just went dead so ... I guess I'd put it at 1/2-3/4 of a workday, which is typical for 18350 lifespan. So to answer my original question, it works reliably just fine on an 18350 including high wattage vaping. An AW battery should give me ~16% more runtime.
The "passthrough" ability is nice and gets you back up and running right away.
