1st atty on my Vivi Nova died after 10 weeks!

[shantyshaker12]

I can't believe it lasted 2 1/2 months! I clean out my nova's about once a week or so,(I don't switch flavors very often). I always use 1.8 ohm heads on my Nova with a Twist battery at 4.0 to 4.4 volts, depending on the juice, theoretically that is to much voltage for the 1.8 head. I like a warm vape though and the 2.2 ohms just don't get it for me. Has anyone else had a vivi nova atty last that long?

It's a pretty good time!! you gave it good care for sure.

I'm working on month two on some original V3 heads, which are a similar style.

I only ruined two because of user error. Pulled out a coil while rewicking one, and popped another with one too many dry burns

Wow! That's awesome. I'm just past a month on the 2.8 head, and it's still going strong.

PBusardo did a UTube review on the Twist and... at 1.5 ohms it would not go above 3.7 volts, regardless of what you set it at (3.7 or anything higher up to 4.8).

So, I don't know what the max for it would be at 1.8 ohms. He did do 2.2 ohms and 2.7 ohms, and at 2.2 it got up to around 4.6 volts max.

So, I would guess... that above 4.0 volts or so you are probably not gonna get any hotter vape, at 1.8 ohms.

Actually, this is probably good because otherwise the juice would start burning once you reach a high enough wattage.

Just letting you know.

For me, and my Vision Ego 2.0s (the heads are virtually the same as the vivi nova), at first I thought they were lasting longer than atties... but then they started clogging... much the same as dripping atties, and it is just a matter of the juice you are using in them, with coffee based juice clogging the worst. So, I am going with the 6 ML bottle of juice for each of mine and then they go into the cleaning queue.

That's interesting, that the twist wouldn't produce more voltage no matter the setting with a lower ohm atty. Is that a protection feature built into the twist?

That's what it looks like. I don't really know if it is to protect the battery or if it is to protect whatever is attached to it. There was a chart going around that showed vaping above 8.5 watts can cause solder to melt or what not... and the 3.7 volts at 1.5 ohms is.... around 9.1 watts. Hmmmm... I remember seeing something that once you get above 10 watts or so then the juice starts to burn... but I have had it burn at a lot lower wattage than that.

The 4.6 volts at 2.2 ohms is 9.6 watts. Not sure what their criteria is. The amperage at these two ohms levels are:

3.7 volts and 1.5 ohms: 2.5 amps (9.1 watts)
4.6 volts and 2.2 ohms: 2.1 amps (9.6 watts)

I guess the bottom line on this one is it most likely cuts off at 1.8 ohms, somewheres in between 3.7 and 4.6 volts... maybe around 4.1.

I'm five weeks into pretty much constant use on the 2.4 head on my Vivi Nova. I follow a pretty strict cleaning regimen, soaking all the metal parts in Everclear whenever I change flavors (which is about every three days). The top cap and bottom cap/stem soak for an hour or so, and then get rinse with distilled water, blown dry, and left to air-dry overnight before re-use. The head, I soak in Everclear overnight, then let it air-dry overnight.

I use it on a Acrilymax, between 3 and 4.7 volts (which, by most accounts, is actually more like 4-5.5 volts, but the AcryliMax is notorious for displaying voltages, wattages and resistance loads about 20% lower than they actually are...)

I imagine I'll easily get two months from my Vivi Nova heads, and when the coils give out, I'm going to rebuild them with Kanthal wire an Nextel wicks.

I have found the Vivi Nova to be very reliable, easy to maintain, and it performs well. I'm looking forward to trying it with my own rebuilt heads...

Sounds like I'm not the only one getting good "mileage" out of the vivi nova heads. I have never tried re-wicking, The coils just look to small for my big fingers, and My eyesight isn't great anymore either, don't know if I could achieve it or not.

Just for the record here... I should say that I noticed in PBusardo's review that the twist on the lowest reading read 3.4 volts instead of the 3.2 it is supposed to read... and then on the highest reading it was at around 5.0 volts instead of the 4.8 max it is supposed to have. Now, it COULD have been the particular battery PBusardo had, and it COULD be that the twist actually puts out those voltages instead of what it is supposed to be putting out but... given that the high and low reading were BOTH .2 volts higher than expected... it could very well be that PBusardo's osciloscope was not calibrated all that well. If this is the case, then the ego is only going up to around 3.5 volts on the 1.5 ohm load... and probably cuts off on higher ohm loads at a lower voltage than noted previously.

In any case, when using a twist, when you increase the voltage from the lower level and keep getting more vapor as you increase it, but then come to a point where you do not get anything more when you increase it, well, that is where it is cutting off.

My apologies for any confusion on this one. It seems clear that there are cuttoffs on the twist but it isn't clear exactly where those cutoffs are.

 

[Zaratoughda]

Oh, I should say here... if you are getting a month or 2 months or longer out of a vivi nova head... why rewick them? You can get them for under $2 each so probably not cost effective to rewick... unless of course you want to.

Thanks for all the info Zaratoughda!
