Fairmana, I do have a little play with the center pin, but I'm just not sure how far I can push it. I don't want to shove the V3's center pin too far down either. Aikanae, I don't have a slot/phillips on my Nauti's center pin. It just seems to "float"
I have tightened down the topper a little bit more - also unscrewed the topcap of the V3. It's a little better, but I'd like it a little closer still....
Thanks for your input
The best thing would be if there were some way to remove the center pin on your Nautilus. Then you could maybe file it down on the end that meets the atomizer, so that the wider "head" of the pin that meets the V3 pin would remain pristine. You'll probably have to do some research and find out if the center pin is even removable and figure out how best to do it. The pin may also be wider inside so that it cannot come out, and that will also affect what end you decide to shorten. You may also need to consider the length of the 510 outer threads on the Nautilus. It's possible that after you shorten the center pin that the outer 510 threads could end up being longer than the center pin. In other words, you may also need to shorten the 510 threads also so they don't bottom out before the center pin does. It will likely take some trial and error on your part (file a little off the center pin and then check the gap and the outer 510 thread length, make corrections, rinse and repeat).
Another thing that occurs to me to pass along is that some V3's have a wider center pin inside the 510 connector than others do. I never had any issue or heard of that being a problem, but it makes me wonder if the wider style V3 pin could contact the outer threads of a topper if the situation was just right. The last thing you want is for the outer 510 threads on the Nautilus to make contact with the V3 center pin and cause a short circuit. If you're V3 center pin is relatively small, it may not be a concern even if the 510 threads bottom out. If your V3 center pin is wide enough to possibly make contact with the outer threads, you may want to consider shortening the 510 threads on the Nautilus so the Nautilus' center pin makes contact first and eliminates that possible scenario. My fears in this regard may be unfounded, but I wanted to throw it out there just in case.
Hope this helped somewhat and best of luck!

The nautilus is known to have that problem. It sticks out ridiculously too far. You got the version without adjustable pin they went to. You have to pull the center pin and file/sand it down. Top or bottom of it, or a little of both. Might need to take a little off the delrin insulator with a razor blade or sand paper to get the pin in far enough.
Just be carefull not to go too far with either. If something was put together it can be taken apart. Search the forum to see how others did it.
Warning- I had the ring up to my oddy before I adjusted it. When I dropped it the atty moved to the side and damaged the threads on the ring. If you can get the atty to move side to side because it's not bottomed out, or tolerance to spec, this could happen. My ring still threads after some coercing.

New Zmax user reporting in....
I did manage to get the center pin of my Nauti up quite a bit, so I do have less of a gap between topper and top of the Zmax. I'd rather not file the pin because I use the Nauti on my MVP, and it fits fine (I can lift the beauty ring up enough to secure w/o any excessive wiggle.)
Loving this new beastie. Need to find the 3100maH 18650s though. I really like it in short mode, but 700 mah on the 18350s kills me.
Just checking back in

I have 2 AW 18490s that last me most, if not all, of the day. With the long cap there is hardly any gap in the middle and it is lighter than with an 18650. Only a little taller than the 18350 mode and a little heavier.
That's the mode I use mine in or else with a 18650 batt. The 18350's just don't have much "run time".
I'm using Efest red 18500 V1 flat tops. 1100mAh. Two last me all day long at 6.5W. Usually do 650-700 puffs per day.
Checking back in on a power output issue I've noticed on my v5. I'm hoping other v5 owners might weigh in on this since it seems that only the v5 is capable of displaying a true power output reading. Here's my last post on it, and the full issue is detailed in posts in the couple pages prior:
http://www.e-cigarette-forum.com/forum/showthread.php?p=14088389
Long story short, I was noticing my power output drop from my 7w setting as my 18650s drained (usually the drop happened when the batteries got down to about 3.8v). I then discovered that I couldn't get output above about 8.5w even with a full battery. I suspected the batteries were damaged from "trickle" overcharging overnight.
I got a new 18650 and a couple sets of 18350s as well as a SODA charger. The 18650 is an efest 2500mAh 35A max discharge battery. By now, I've put the 18650 through probably 2 or 3 discharge cycles. I *still* can't get power output above 8.4w.
My stacked 18350s, however, have no issue reaching the highest outputs the v5 is capable of. I've also been very pleased with the battery life. For me, this solution is working great.
However, this makes me question whether any zmax is capable of putting out double digit power outputs with anything less than stacked 18350s, or whether this is something peculiar to my device.
I'd like to ask other v5 owners to weigh in on the max power outputs they've achieved with single batteries, and what batteries they're using. Again, I'm being specific to the v5 since my understanding is that it's the only zmax version that displays true power output.
Thanks in advance.

I do not own a v5 but a mini but the internals are the same as a v3 I believe. When set at 15w, the measured voltage under load coupled with the resistance in use, give me 14.85W using an efest purple 18350 battery.
You do not mention what rating your coil has but remember that in single mode, the chip won't go over 6v so the coil has to have a resistance that coupled with 6v, generates at least the power you want.
Obviously something is wrong because in order to only get 8.4W, you would need an coil with a resistance of 4.3Ohms which I doubt you have...?

I was just wondering about you issue today and was going to quote with question. Assuming you have all contact points and threads noalox'd ... The only way you should get only 8.5w on a single 18650 is if you are running a 1.4 ohm coil. The you would peak at 8.5w shortly after a fresh battery.
It's a different firmware version. The v5 display shows two lines of information, one for power/voltage/resistance/current, and another with a battery indicator and puff counter. I can't say whether the chip is different in other respects or not.
My coil reads at 2.3 ohms, so 6v would be more than enough to achieve maximum power output.
Just put on a new 2.6 ohm coil. With a 18650 battery reading of 4.1v, and setting the v5 to 14w, it displays power output at 7.7w. Current is 1.7A. On voltage setting, when set to 6v, displays voltage output at 4.7v and same current output (1.7A).
Did that this afternoon.
Obviously Jeremy, I've come over to your stacked battery fold in light of my results, and have to thank you for showing me the light.
Strange though, isn't it? Maybe it's a problem with my boost circuit. Hopefully it's not a problem for other v5 users, but I'm certainly curious to hear from them.
I just fired 10.0W on my V5. Used a 2.0Ω carto with 3.8V left on an Efest red 18500. That Efest red 18500 is rated for 6 amps continuous, I believe.
I won't be doing it again. Don't want to burn out the carto.
I won't be doing it again. Don't want to burn out the carto.
Incidentally, when firing the set-up above at 6.5W I see 1.8A on the V5. At 10.0W I see 2.2A.

I appreciate the test fire, yzer. Don't kill a good carto for science, though. [emoji13]
