Rayon wick, better flow, flavor, saturation and Nic Hit!

[JeremyR]

I know the first 20s were not RMS which caused issues.. And they had some other issues that have been taken care of.. Now with the 50 it seems all the issues have been resolved and I like the stainless 510 on the 50w.. A stainless 510 is also a MUST have... (The zmax is stainless too) I have been reading up on the eleaf so I'm aware of the older problems..

Oh I won't buy a dna 40, IMO way too many problems reported and the technology is not perfected yet.

Also I don't care for the flask design myself. Being I've only had tube mod its gonna be different.

My iStick displays AVG power. Not big deal, just multiply by 1.11 or add 10% for a ball park number. The real "problem" is that people expected RMS and got AVG which made it appear to "hit" harder or hotter.

I don't change tanks on my iStick, other than to fill it every two days or so. An advantage of the Fogger, so the 510 is holding up just fine. Worst case, I'll take it apart and put in a Fat Daddy.

After read this thread for about an hour and checking bottles to see if I had any Rayon (which I didn't) I ask the wife to stop by Sally's and pick up a roll of 100% Rayon. I guess I'll be testing some wicks tonight

Added: just realized it's my 2 year vaping anniversary

Just make sure it says 100% rayon on the box. 12.00 for a giant 500ft box.. Unfortunately I haven't heard of any Sally's that carries a 40ft box in stock. But they may be willing to order it for someone.

2 years.. Perfect time to step your vaping up to the next level with rayon. Just pop in with any questions or if we can help direct you. I know the thread is crazy long..

Most important is check the wick for the first few hours to a day to see if it looses contact with the coil. If it does you know you need more density..

Pull the rayon in pretty tight. So tight you can barely get it through without grabbing both sides close to the coil to pull it tight kinda like stretching a rubber band to make it thinner. This will help you get the density through to the other side of the coil.

Use about 2 times what you would with cotton to start with. If you taste rayon or muted flavor its too tight. If you get dry hits its too loose.

The problem with the iSTick I have is in no way related to the Peak vs. RMS.
Probably already clear but posted so there is no little confusion.

That's the best deal I've seen!... But now I'm looking at the Sigelie. Lol this could go on for a while.

I may have to pull the trigger on that though... Earlier tonight I was all about the i50 when I read a post by a guy that was saying he was at 5 days of use with the i20 and still at 90% battery... OK he was only vaping at 6w but still that's a long time.

Oh and I have a rayon wick in a evod that's been there for 3 months in juice and it hasn't disolved, melted, decomposed, or anything. (Truth) But for some reason when I taped my fire button to the on position and came back later the wick was gone.(bs)

 

[JeremyR]

Well I've been doing a lot of reading tonight, seen a lot of different things id like to post about.. But one thing I wanted to mention - on topic..

You know how kanger has the cotton coil heads now; in about a year or two I bet it will be rayon.

Oh I won't buy a DNA 40, IMO way too many problems reported and the technology is not perfected yet.

Also I don't care for the flask design myself. Being I've only had tube mod its gonna be different.

Funny you should say that. The first 6-8 months since I began vaping I couldn't stand the box form factor mods. Hated them! Then I saw the Flask. It is perfect ergonomically. Dual 18650s and 40 watts (more than I use on any of my tanks). I absolutely love it. The only tube mods I use now are mechanicals.

I'm really liking the DNA40 as well. It's not just to prevent dry hits. I'm a high wattage vaper and the DNA40 keeps me from overcooking my juice and there by producing harmful chemicals. It is the "cleanest" vape I have ever had. I can tell a huge difference between it and my mechs. Two nights ago I finally put a dripper on one of my Flasks and I am slowly weening myself off of my mechs.

Most of the issues with the DNA40 are user error, specifically, connection issues. It's new technology and there is a learning curve. With Ni200's super low resistance, one can't be sloppy with their builds.

lol. Those that want to help evangelize Rayon and/or limit the damage created from unfounded posts (like the recent one) just need to keep alerting the group when they find one. If anyone doesn't feel comfy taking a stance, just posting a link in this thread directly to the post (copy/paste from the post # in the upper right corner) in question... and if you don't feel comfy doing that, you can feel free to PM me the link. I'll share it and such

Thanks PaulBHC, for the heads up... and those who posted follow-ups and got involved, as well as any that may have only 'liked' the comments.

While I can't confirm that most of the issues experienced with DNA40 devices were user error (especially since many of the early issues were from pre-built devices), it sure seems like there have been a lot of user errors solved in the threads here on ECF. I like the concept of temp control and I like that a big(ger) name like Evolv is adapting existing technology from other industries into vaping when they think it could better our experiences. Now if they would only start including the profiles for Ti as well and tighten up the temp tolerance Oh... and they could include a little baggy of Rayon with each board, lol.

 

[Dave_in_OK]

My first take on Rayon: 500' will support my town for years!
I wanted to test it without changing anything so I dry burned the gunk off the coil as I would when rewicking with cotton. Then I inserted the new Rayon wick tight but not to tight added my ADV as I would normally (I Drip) checked it out and added a lot more juice as Rayon seems to really hold juice well. When I was happy with the feel and look I took my first two hits, now I'm still using a ZMax V3 which was set at 12W, without thinking I dropped down to 9W as I was getting a nic rush. The flavor is clean real clean!
Next I let the juice run down to where it was real close to a dry hit; if it had been cotton I would have had a change in flavor, but not with the Rayon the flavor was still true.
I then tried to flood my set-up to see how it handled that: it no problem.
I just swapped out my battery, normally I notice a drop off at 3.6V, it was at 3.4.
Bottom-line is I'm trashing the cotton and getting on the Rayon Bandwagon Thanks Jeremy

The main issue (screen scramble) with the DNA40 has been resolved.

Another issue that has popped up recently is a false "Weak Battery" message. It is my understanding that this is not an issue with the board but rather a connection to the board issue. This is happening even on factory built devices. It has happened to me and others on the Flask and I just saw a post in the DNA-TP User's Group on fb stating he is getting the message on a VaporShark with the large screen.

However, the user errors I was talking about in my previous post was not about building the box but rather building their RBA. If one doesn't really crank down on the coil mounting screws the board will get incorrect ohm readings and will jump in and out of TP. Also, while contact coils will work, it's really not a good idea to dry fire them imo. I built that way at first and before I could get through a single tank, the coil was leeching black gunk into the juice and the vape had an off taste even before the leeching. As soon as I started using spaced coils and didn't dry fire them all was back to normal.

And yeah, many user errors have been corrected from knowledgeable people here at ECF.

 

[tchavei]

I got the fake weak battery but only in C mode. In F mode everything was fine (besides garbled screen). In C mode I even discovered a weird demo mode lol... Says it's firing, heating up and hitting temp protection but the coil is cold... No actual ignition. Another bug is the board firing at 40W when turning of TP from C mode regardless of what W were programmed.

Good to have you on board Dave! Welcome to the next level of vaping! Glad you got it right away.. Below 15w its really forgiving on density.. When you start going higher the density becomes more important.

Now you see why people just give it away.. Its just such a huge amount for 12 bucks...

As you see how great it works for yourself... This is the reason we get upset when people spread misinformation and hold other vapers back from trying it. Its just hurting fellow vapers by stopping thier progression to a better experience.

 

[JeremyR]

Just like they keep saying to me for the last year that stacking batteries in series is dangerous. Actually parallel has more risk. And these people actually say stacking will drain the batteries faster.. Omg really them why does 2 18350 last me 2-3 times longer than a single 18650, with loads of power... They say the amp load is doubled.. No its halfed in a regulated device because you have an 8v input.. Misinformation again..

The sigelie 100w is one of the most powerful devices because it uses series batteries to make an 8 volt input not a wimpy 4 volt input. I just watched the pbusardo review on it, he mentions it may be unsafe and can't believe it lasted him so long.. Stop listening to false Info P. He couldn't even run it to cut off. Lol

Now if I could only look past the plain box design.. The i50 is wired parallel so I do have major concerns with it real ability to deliver consistent power as the battery drains. I'm a high volatge vapor right now. So getting 6v from 8v is a lot easier than getting 6v from 4v

Oh and when I promoted the first bottom vertical coil. People said it was no better... But now look at the market.. Flooded with bottom vertical coils 2 years later. Your welcome fellow vapers.

: End rant, sorry read a lot yesterday.

 

[awsum140]

Jeremy, the higher voltage does allow a higher efficiency for the boost circuits used without question. A friend ran some computer controlled tests when the Vamo first came out and a stacked pair of 18350s lasted longer and delivered more consistent power than a single 18650 even though the 18350s were only 800ma versus the 18650 at 2000ma.

The dangers of parallel can be fairly easily mitigated with a simple fuse. That will prevent over current and the resulting overheat of the batteries. The fuse only needs to have a higher current capacity than the mod circuit draws. For example on a mod that draws 10 amps a 20 amp fuse would provide excellent protection. As long as the batteries are fused, parallel should be as safe, or possibly even safer, than stacked.

I would speculate that keeping the batteries in pairs, paying attention to which one goes where and monitoring them carefully when charging for voltage equalization would be a good practice. That is also true for stacked batteries.

[JeremyR]

I do that, and I'm not saying parallel is dangerous but if they demonize stacking, really parallel needs more caution in the build design. But I'd go either way with no problem. We have safe batteries now a days.

But like you said it was proven to work better but people are held back by over zealous fear mongering.. So, still to this day years later... not many people do it because they are scared, like they are scared of rayon..

I bothers me when people say oh you will only get 800mah stacked.. A single 2000 mah will last much longer..Really more like equivalent to 4000 mah in real world with buck efficiency and two more volts to run through.. While always staying above 6.5v input... Considering voltage drop with a single battery I can't run one below 3.8 without noticing power loss..

 

[JimmyDB]

A tad bit of warning... when selecting fuses, always check out the datasheets for the amount of time before the fuse trips at a given current. It's always a game of the fuse breaking the circuit BEFORE the batteries fail or enter thermal runaway (or the wiring fails). Check out this PDF for an example http://www.littelfuse.com/~/media/electronics/datasheets/fuses/littelfuse_fuse_501_datasheet.pdf.pdf

Generally, for applications like vaping... I would suggest to use a lower rated fuse, since you know it will take considerable time to fail (based on the datasheet)... time you wouldn't be holding the button down for, etc,.

 

[Kingboomer]

FWIW...(<<<late to the party again )

I have an istick 20W topped with a Nautilus mini (custom 1.8 coils w/ rayon wick), and have absolutely no complaints. I've been using this set up since Dec. last year. I've even dropped it once or twice, still fires where I like it.

[JeremyR]

Sorry I had to rant, some posts around forums got under my skin yesterday.. I've been fighting the stacking misinformation as long as rayon. So i encounter constant misinformation and debate at almost all times. With supposed experts trying to make me look stupid..

My only goal is to make peoples vaping experience better, if they will just listen to reason.

OK now I'm done, time to turn a new leaf today. I had to vent here because you guys are my friends.

 

[tchavei]

Oh don't worry. We know perfectly what you mean. I'm dealing with the DNA40 cheerleaders myself in my own twisted way
