another first post and quick phoenix bc and vivi nova question

[tmart011]

hi everyone, i switched off analogs may 11th with great success so far and wanted to make a first post since this forum is an amazing place. Started with eGo, got an eGo VV, cartomizers, attempts at stardusts etc etc. Most of you know how this going in the beginning with trying to find what works best

I also had a question regarding the newest gotvapes phoenix BC's and Vivi Nova 2.5 .....do these still have issues regarding juices cracking the tubes at all? Not much of a cinnamon person but i do like stuff like mt dew and maraschino cherry. I tried maraschino cherry in a stardust (without proper research) and it cracked within 2 minutes.

thanks

troy

No, they don't crack. I have used both with cinnamon, maraschino cherry and other juices known to crack

And you can buy a metal tank for the Vivi Nova to completely eliminate any worry about cracking. They are about $3.

thanks for the replies, thats great that you tried and it seems good im really liking that flavor.

i did order a metal tank to eliminate the fear, but using it means you cant see the amount of liquid left....just realized how picky that sounds lol

thanks!

It's not, I feel the same way. I put my metal tube on last night just to try it, I hate that I couldn't see how much juice I actually put in, and how much I have. I wish they would offer extra plastic ones

Mucho congrats on your nearly 2 months and welcome to the forum.

I just had a v2 vivi nova tank crack on me today using boy wonder (which is a not terribly strong pink lemonade+ flavor.) It wasn't a quick catastrophic failure, but I had two cracks develop in the tank and they were growing slowly before I dumped the juice and rinsed it out. I haven't tried it in a 2.5 tank yet, but I'm not particularly keen to try until I have a couple more of them laying around as spares.

I did pick up some metal tanks this afternoon, and one thing I'm noticing with it is that they get awfully warm. I'm not sure how much of it is just the weather (because it has been bloody hot today,) nor am I sure if it's getting hot enough to noticably affect the juice. I doubt it would be much of an issue if you're sitting in the air conditioning, but if you're going to tote them around outside, it's something to be aware of.

I'd be interesting in hearing how the V2.5 Vivi Nova tanks hold up. I have both V2s and V2.5s. I mixed the tanks up and cannot tell for the life of me which one is which or else I'd put them to the test. The biggest improvement on the V2.5 is supposed to be the crack resistant tank, but I've heard no evidence that it's any different than the V2. You certainly can't tell by looking. You don't suppose a manufacturer would lie, do you?

Meanwhile, I got some metal tanks. You get used to them pretty fast and I've gotten to where I only have to take a peek a couple times in the course of a tankful. After some practice, you can just tell when they're getting critically low. I don't like running them dry anyway. The fact that they're not transparent no longer bothers me at all, and I may just start using them most of the time.

The material of the tank changed with the 2.5 version. The 2.5 is resistant to cracking. I have put maraschino cherry juice in mine and it didnt crack.

I have not noticed the heating of the metal tanks, but I hate that I can't see how much juice. I feel like I'm using a carto again. I wish they sold the plastic tanks

I don't see any obvious difference, either. My impression is that there is a fair amount of mixing whatever part are laying around, but that is just a WAG on my part based on the atty heads we ended up with in the pair we bought yesterday. We ended up with 3 1.8 ohm attys, 2 2.4 & 1 2.8. The 2.8 was the only one that matched the stated resistance, and the 1.8's were wildly off -- 7 to 9 ohms! The coils are pretty well mashed, which is probably the issue.

I bought them to rebuild, so I wasn't too put out about it, but it certainly doesn't do much for my confidence in their QA.

On the the plus side, they are super easy to rebuild and I'm very happy with how solid the tanks feel. I don't feel like they'll just come apart by accident, which is a nice change from the other tanks and clearomizers I've tried. The second time I filled a smoktech dct, i ended up with a lapful of juice. I don't care to revisit the experience.

 

[tmart011]

i received the bc phoenii (lol) and the vivi today and immediately put maraschino cherry in a phoenix, because of this thread, and so far so good! i really like the vivi but i LOVE the phoenix bc so far. Already planning to order more but im not sure how long they last (compared to cartos etc). either way both products are great so far, such a step up from having to top off cartos all the time

Little known phenomenon. The heads on the Vivi are wildly off when you first get and meter them. By the time they have burnt through a half a tank or so, they drop significantly in resistance and end up pretty darn close to the labeled resistance. I've never had one meter 7 to 9 ohms though. That's crazy. Not to insult you or anything, but you ARE deducting the lead resistance, aren't you? I don't think I could make a 9ohm coil if I wanted to, given the space available for the coil to fit into.

Mine were all about 0.5 to 0.9 ohms higher than labeled but, after a tankful, each one settle within 0.2ohms of the stated resistance. Even the ones I rebuilt started out about 0.5 ohms higher than they ended up after a tank. I've had to add a wrap to compensate for it because it happens every single time.

I know for a fact that Gotvapes had the factory send them a mishmash of coil heads with the 2.5s. Some were long wicks and some short wicks. I rebuild them as well, so I didn't care, but I prefer the shorter wicks.

 

[delwin]

That was the total resistance on those atty heads, not the coils themselves. I have an ohmeter with a 510 connection, which is what I used to measure them. It seemed crazy to me, as well, so I set them aside to look at more closely with my good multimeter later. This ohmeter is new, so it is possible it's at fault, but I got expected readings from other attys I tested with it. I won't really know what to think until I get time to sit down and look more closely next week, but it is clear to me that out of the box those atty heads were junk.

What juices Crack the ViVi Nova v2 tanks?

 

[Flyer]

Been running a cinnamon juice in one of my VN 2.5's for 5 days now, the tube is still perfectly clear and no signs of cracking.

The Vivi does not have a soldered connection so it depends on how tight the connection is when metered. The coils have the stated resistance, since the length and resistance of the wire is known, the added resistance is usually due to the wires being pressed to make a connection. As stated before, the numbers quickly fall in line once it is in use.

Still, some cartos are way off the stated values and it has only recently become common for people to meter them before use, so it seems to be more common now. Actually, the values are better regulated now, it's just that more people are reporting what they are finding.

IMHO

 

[delwin]

I finally had the time to fool with the heads I was having issues with, and this:

The Vivi does not have a soldered connection so it depends on how tight the connection is when metered. The coils have the stated resistance, since the length and resistance of the wire is known, the added resistance is usually due to the wires being pressed to make a connection. As stated before, the numbers quickly fall in line once it is in use.

...is almost certainly the issue I experienced with them. When I metered the three 1.8 ohm heads I got in the last two boxes, they were metering between 7-9 ohms, but one of them kept swinging between 7 and 9. I pulled that one apart and one of the wire legs seemed to be shorter than it ought to have been, so I opened up the other two, and sure enough, that leg was short enough to be making a connection, but was apparantly floating around enough to be flaky.

I rewrapped the coils on the other two, rolled up gauze for wicks and put them back together. Both are now dead on 1.8 ohms like they were advertised. So in the end, the problem appears to have been bad connections. I suppose, considering how these things are held together, it's a wonder there aren't more issues like this occuring with them.

I still haven't seen/noticed a drop in resistance on these, but that might be related to how careful I've been seating the wires when remounting the coils, and it might just be luck. Hard telling, but after rebuilding, the heads all seem to be working well.
