vivi nova problems

[popster]

hey guys.i'm quite new to the world of vaping been using the itaste vv express kit for a couple of weeks then moved on to a vamo just 2 days ago now i've encountered some issues (maybe it's just me) the vivi nova starts to get really hot.not to the point where it hurts just touching it but i'm afraid maybe something will melt or something.the vape experience is ok nevertheless.i'm using a 2.8ohm head on the vivi,but when i checked the resistance using the vamo,it states 1.6ohm.could anybody here comment about this.really excited to vape after 5 years of heavy smoking

You may have a knock off. But, even with that being said. I've noticed that the etched resistance doesn't always line up.

Run at 3.7V or there about and you won't get too hot. But, the lower resistance creates alot of heat anyway. Someone correct me if I'm wrong.

 

[popster]

yeah,i've been running it at 3.9 to 4.4 and i've found that 4.3 is my sweet spot as i got superb hits but then the heat from the vivi really bugs me.i've tried reducing it to 3.3 to 3.4 and the heat reduces slightly but it's still there.even tried using a stardust.still got the heat problem.actually the vamo states the resistance of the stardust at 4.4ohm.haha,don't know how that happened

I have had simular experiances with the vivi's. I use vw and typically vape at 7-8 watts. But on a vivi if I use a 1.8 ohm head (usually tests between 1.6-1.9 ohms) the top gets very warm and after a few vapes I starts tasting that hint of melting plastic. So if I am using the vivi with a 1.8 ohm head, i drop down to 6 wats (3.3v - 3.4v). No problem with the 2.4 or the 2.8. Both of thoose allow me to use 8 watts comfortably with no significant heating of the outside and no melting plastic taste. I also have had a few 2.8 ohm heads that were mislabled 1.8's instead of 2.8's.

Between shoddy quality control, and the large amount of knock offs that get sold, I was noticing a great deal of difference between the 2 vivi novas I had, and with the replacement heads I bought. Just using them on an Ego twist, I would notice loose draws, tight draws, overheating bases, frequent leaks and the occasional burnt taste, even when using them at 3.7v. Maybe I just had a run of bad luck.

haven't tried the vw mode yet.just comfortable with the vv mode but yeah,maybe i'll try switching just to see either the heat problems goes away or not

did not experience the burnt taste,draws are ok but yeah there are some leaks and of course overheated bases.really starting to be suspicious whether my nova is a knock off

I noticed that the Vivi's (along with others) can run really warm on my Vamo if it's in mean/average mode. In RMS it runs much cooler. Hold the little button on the right for 10 seonds until it reads "No2". Also, try running it in watt mode if you already aren't, I believe it's -hold the left small button for 10 seconds-. Set it to about 6 watts and try it out.

hey,it actually kinda works.set it RMS and used vw with 6 watts.the heat problem decreases quite significantly but it's still there.even though at 6 watts i'm not getting that sweet spot i usually get in 4.3 volts,the vape is ok i guess.if there are some other ways that i could retain my preferred settings without destroying my nova haha,i'm gonna be a really happy man thanks for the tip

Does it do the same thing with a different head?
None of my Vision Vivi Novas do this.
I'm thinking it may just be a bad coil on that one head.
The clones seem to have all sorts of probs.

I love vw mode. For the vast majority of the clearo's I use (Evod BCC's and other Kanger clero's) I don't have to worry about what resitance head is in the clearo. Set it to 7 wats (or 7.5 or anywhere between 7 and 8) and vape away. The only time I have to change it is if I am using a 1.8 ohm on a vivi, but fortuantly I only have one of thoose left. (Would toss the head, but cant bring myself to toss something that is still working lol)

i haven't tried other heads yet.gonna finish my e-liquid first then i'll try changing the heads.wanna try the 2.8ohm.correction to my earlier post,the current head i'm using is 1.8ohm not the 2.8

just tried the vw mode.it's ok but it's set to 6 watts and i didn't get quite a good vape as when i'm using the vv mode with 4.3volts.probably when i changed the head to 2.8ohm and set the watts a little bit higher then maybe i'll get a good vape.thanks for the info

I have two of the 3.5ml aClear clones, haven't had any problems with either. Don't know if I'm just lucky or this clone mfg is a good one, but wouldn't hesitate to get another.

Unfortunately, that's pretty subjective due to all of the possible variables. I notice that the smaller 2.5mL tanks run hotter than the larger Vivi 3.5mL tanks - which makes sense, because there's less area to dissipate the heat. Also, adding onto that, using an all metal, or windowed metal tank will also create more heat. My 2.5mL tank with an all metal tube is an oven, and will quickly discolor the fluid.

My recommendation, and remember, I'm still pretty new to this too, is find a dealer that sells genuine Vivi tanks (if you want to stay with that particular brand; which I love too) and when possible, use the bigger size with a higher resistance coil. That has been the winner combo for me anyhow.

Good luck!!

I have found that especially when chain vaping, atty tanks like the Vivi Nova transfer heat to the casing via conduction because the components are physically touching to prevent leaking, and the heating coil and down tube also warm the liquid in the tank, conducting that heat to the outer shell. The atomizer builds up heat rapidly, but it dissipates much slower from the device. You aren't in any danger of melting anything with a genuine product tank/clearomizer/cartomizer etc. However clones can be built with varying degrees of quality. They will feel warm in your hand, but you won't wreck your tank. Most PV's have limiting power supply systems to prevent any damage, but the worst case seems to be burning out your coil like a fuse due to too much current or heat on something like a mechanical APV whcih has no such protection.

oh,i'm currently using a 3.5ml nova with windowed metal tank.seeing all this sort of variables makes my head spin,coz i'm really a newbie at this,haha so yeah,i will try to learn all this stuff and take up what you recommended,though it's gonna be hard finding a genuine dealer here.thanks a lot

so that means i could spend a lot on buying replacement heads.next time i really have to check whether the novas i'm buying are genuine or not thanks for the info

You actually won't spend a lot of money on heads. Many folks, including me, are very happy with their Vivi Novas. A head will last you 2-3 weeks, although I am using one thats been going almost a month already! If you get them online somewhere, just buy a couple, and it should last you a good while. Atty coils are like lightbulbs. You never know quite how long they will last till they burn out.

I have one Vision Vivi Nova head that's done about 150 ml. of a clear, straight-menthol e-liquid over the months. It's been on a Lavatube at 3.4-3.5 volts. After every 40-50 ml., I disassemble it, thoroughly clean everything in hot water in an ultrasonic cleaner, let everything dry for two days, reassemble and dry-burn. It's still going strong. It's marked "2.4 ohms," but both the Lavatube and one of my Vamos tell me it's 2.8-2.9 ohms.

SRusackas is right: Vivi Nova heads are a lot like lightbulbs!
