yes it does not read it out for you on the screen, it simply determines the resistance and then based on the inputs they made at the factory based on a safe variance you will get a voltage range that is acceptable for your resistance and give you that range. just like in my video. you however can go out of the that range if you choose, its simply reading your carto and determining a safe range to stay in.


Excellent - Thanks bad! I must admit, if they're going to read it, it doesn't make sense for it not to display... if one of my students wrote it that way they'd be rewriting I expect.

Mia culpa yiddleboge! :oops:

Ok so I have a fix for using v2.5 heads in a v1 nova tank. To reduce any leaking and vapor backing up inside the tank.

I took one of the silicone caps off a V1 atty head and cut off the top so it was just a small tube. Then I slipped that over the silicone sleeve on a V2.5 head. I had to remove the metal grommet inside to make it easier. I did not push the over sleeve on all the way down the 2.5 sleeve. Just enough so that it created an extra lip of a couple millimeters above the other sleeve. Place the grommet back in then placed it back on rhe 2.5 head. Put the 2.5 atty with double sleeve in the v1 tank, adjusted it for center, and then screwed down the v1 tank cap.

Had a look without the drip tip in to make sure the airhole wasnt obstructed and... voila. works like a charm.

If you want to cut the wicks, cut so they are just touching the walls of the tank, or a little longer.

As for your "dogged" head - it sounds like it should be fine. It's the white rubbery "hat" that came off, right? And the little metal doohickey inside it that fell out?

You are speakin my language g/f!!

purple buzz pro??? ohhhh myyyyy

FRELL! mine fell off the table on my twist and popped off. did something to the threads i think cuz it wont screw into that battery now... still threads into other batts but doesn't feel exactly right. i thought at first i stripped the head in the twist but other stuff seems to screw in mostly ok if a bit loose till it hits bottom. which also this nova wont screw all the way down on most of my batts unless i really tighten it down - it started out this way and its not the center pin this time. i think the male threaded part might be a hair long.
about half of my heads metered right (2 out of 6 one was only off a hair) i'll have to make a little chart lol so i just took the lowest one i think was 1.9ohm and its working great no bad or burnt taste only got a dry hit once and realized i had bumped up my twist without knowing - dialed it back down and its good to go.
i'm really liking this puppy on my twist - its tied with the phoenix bc as my go to device right now

on another note i was wanting to make something and could really use some burned out stone 2 or 3 bases or caps or any other parts ect nova parts could work too... i would gladly pay the shipping or whatever for somebodys trash ;)

So the 2/2.5 is supposed to have the hole out the side of base right and not where it screws in? I bought 2 of these and I'm thinking I didnt get 2.5's also there is juice or some fluid around the drip tips on both is this normal? Leak testing maybe? You can see the red which looks like copper reflection? But there are some droplets in there. If this normal just let me know but the base does not have a hole anywhere except the stem

Nope...V2.5 has the airholes on the connection stem.....above the threads. V2 had them around the base of the tank....in the knurled ring thingy.

So I got around to putting everything together annnddd... has anyone tested the resistance on the heads?

Mine are WAY WAY Off:

2x Kits with the following: (Listed Ohm \ Actual Ohm)
1.8 / 2.2
1.8 / 2.8

2.4 / 4.1
2.4 / 4.3

2.8 / 3.4
2.8 / 3.4

I am working my way though the first 1.8 which is really 2.2 but so far there has been no change in the Ohm Load. I read that they will drop in load as they are used but the 2.4 which are in the 4's??? I checked the coils to make sure they were not touching the walls or visually defective in any way. Hit a quick fire on the mod to make sure they worked and they all worked so if I am doing it wrong please let me know.

So my question is did I get bad heads or is this a known thing or maybe I am doing it wrong?

I am using 2 different multimeters set to read Ohms put positive on the bottom and the negative on the screw in. Tried both ways same read (which it should be).

I will say the construction seems pretty solid, no leaks and the lowest ohm I had 2.2 which is 6.22 Wattage-ish on 3.7 taste is not too bad, no dry burns as of yet but the rest of the coils are just going to be less and less wattage as they are higher resistance and I do not have a VV. I may try the 4.3 on 6V which would be about 9 watts so should be ok but the rest of the heads may not work for me without a kick or VV system correct? (being too cold or burning from too much voltage)

* Note I realize that the numbers will be somewhat skewed due to voltage on load. So in most cases they will have an even lower wattage.

Yeah I know, shouldn't be any resistance from the leads I wouldn't think. I just loaded the 2nd vivi with the 4.3 Read on 6V and it's pretty damn awesome. Probably 5.6 V at 4.0 ohm puts me around 7.8 Watt pretty tasty if I do say so. 3.7 V is pretty mellow and a lot cooler in temp. So I guess the middle ones are by best bet.

I did Dry and Wet. Resistance shot up by .2 but now something interesting.... I used the (marked 2.8 / 4.3) on the 6V pulled it off and now it reads 3.0 However, after being fired on 3.7 it did not change so maybe the 6V "burned it in" and its at its actual resitance. Gonna check it now on the 1.8 as I didnt fire it on 6 only 3.7

Testing Results - 1.8 - Reading 2.8 Before 6V now down to 2.1 Gonna fire a few more times see if I can get it to 1.8-9 (2.1 Final for now see if normal use drops it in a few days)

@krystm Did you check the resistance dry or with juice in it? For me the resistance shoots up once there is juice at the coil. If you tested dry I bet they would come in at close to stated ohm. My 2.4 shows 3.1 atm.

My 2.4 head is measuring 2.6 on the ProVari, with juice.....second tank full almost gone

Been a long time user of the stone tank and finally decided to give the vivi a go. I was having problems with the center post on the stones getting pushed up and not making contact with the device. Right away the vivi seems to have a robust center tube that should prevent this.

+The replaceable heads are a great idea. Makes changing the coil so much easier.
+Build quality is great.
-The coil is one thing I wish was more like the stone. The vivi's coil seems more like a ce2 coil then a stone. The stone had a very robust coil that was wound so nice and neat. I think the thickness required a longer coil and more wraps thus giving more even heating.
-The novas coil is also wrapped quite tight around the wick.
+The head has a lip that keeps the seal from riding too low making it easier to keep the performance uniform.
oThe performace at first reminded me of the stardust. Too dry for my liking. After the first tank break in it really picked up and has been quite good.
-last quarter tank starts giving dryish hits. Not a big deal just need to keep it topped off.
-Vape is cool. More like an average carto, not the cannon that was the stone. Just have to turn up the voltage no biggie. haven't tried the 1.8ohm head so may do better there. (ran the stone 2ohm at 3.3v and get much better performance than nova 2.4ohm at 5v)
+No leaks or sputtering. Which was an issue with the stone.
+the new top cap design makes it easier for juice to get back to the coil. Not as much of a juice catcher up top.
-not as thick a vape as I'm used to, but with more breaking in/different heads this may change.

Overall I like it a lot. I think it would do much better with the coil wire the stone had. The internals are nice and sturdy. mess and sputter free. Could use a looser coil. Less fuss compared to others. I give it 4 haftdoits out of 5. Can't wait for a version 3.

Yeah I am trying to find the best flavor for my stuff and seems 6.2-6.8 Watts is my target goal. As around 5 its pretty good and passable but using the short few hits on the 6V the taste and heat are there. Hold it too long and it starts to burn. I really want to like the Vivi but without having a VV or VW I think it may not be ment to be for me with what I have. Next project is a box mod to dial in the wattage and if I can get it close enough that way I can use what I got and can just get the right Ohm carts / heads depending on what it is.

Right now Carts are giving me better flavor, the Vivi is softer with more taste but to get that I am either getting a cold vape or risk burning it up from holding it to long.

I think the Kick is my best bet but I can't use it in my bombshell unless I get the smaller battery which I guess I could do.

Uses an 18650 or 2x 123As. The 15xxx battery with kick would work in place of the 18650? Forgive me as I haven't done much research in this yet.

Interesting. harmonic may be right. Running em hot may have caused some shrinkage. It's possible the manufacturer factors this in. So it may come in high but once used they shrink up. Man just tried 6v and these perform pretty well HV! I'm so used to the stone I didn't think it would handle 6v too well. Didn't change my resistance though. I'll post when I have tried the different heads
