ProVari Variable Voltage Mod

[Wylie]

Uke, I have been running the new Provari Batt now for 5 days, the thing is a monster, run times are way way way longer then the AW IMR 18650 your gonna like it.

Five days?! It's only a 2500 mAh battery, right? On a 2900 mAh AW I'm only getting two days on another device.

What voltage are you using? How often are you using it? What resistance is your atomizer?

i think he means 5 days total with few charges. and lots of run time.
i should get mine in today. to test.

My ProVari only goes down to 3.3v, so you must have a different version. If I go down past 3.3v, it swings back around to 6.0v.

And you should be able to go to at least 5.0v on a 2 ohm atty/carto. That's where you'll hit 2.5 amps.

EDIT: I'm now thinking you mean 2.4v on your battery?

No, just my fat fingers hitting the wrong key!! I meant 3.4v. I understand about 5.0v hitting 2.5 amps but I keep reading about people getting errors below what should be 2.5 amps. Again, I've never had one issue with mine. I just want to make sure the early issues with the low battery indicator have been taken care of before I order another one.

2.4 ?
that is lower than it is supposed to go... hah
from what i have read, 3.5 is the designed cutoff voltage...
some are getting early blinking around 3.7 which is to soon.
I have had 2 Vari's from first run, used every single day for 6-7 months... cutting off at 3.5 ...
the issue (early blinking) seems to have started no more than a couple months ago.

I use a 2.0Ω LR Boge carto in a tank on my Provari with no problem and can go as high as 4.8 volts without an issue. I keep hearing about people having issues with errors at these levels. If I remember correctly, there is a 2.5 amp limit on these, right? The only thing stopping me from buying another Provari as a backup is that each one seems to have a life of it's own concerning when the low battery indicator starts flashing and where the amp limit kicks in. I can go as low as 2.4 volts before the low battery warning even thinks about starting to flash. Have they got these issues ironed out yet? Am I the only person whose Provari works perfectly as advertised?

3.4.... close enough... I hear ya Pete.
New spring is supposed to have something to do with the fix...
I'd like to see a laymans explanation myself... being a not tech type.

Ordered mine last night, cant wait to vape with it. Im afraid its going to be a long wait for it.

Congratulations!

Except that chart may as well be complete bollocks .. it shows way higher currents on the 2.2Ω than you can actually use. I was really annoyed when I based a purchase on that chart initially and also grabbed a pile of 2.2Ω bits n pieces, only to find that 4.5V or so was causing the E2 and once the atty was run in and was around the 2Ω or less mark I was down to eGo voltages again, 3.5V .. E2.
Now I use a minimum of 2.6Ω (new) and grab 3Ω stuff when I can find it. ProVape really should update that chart .. I don't know if it was generated with an old version of the ProVari but it may as well be written by fairy's for its actual resemblance to real life. I nearly sent mine back for warranty..
Try the upper values in that chart and you will see what I mean .. not even close.

EDIT: I have done some retesting with a thin magnet attached to the bottom of the IMR 18650 battery and the E2 error does not occur till much higher voltages now. Suspect I was getting a substantial voltage drop at the negative battery terminal, it was certainly warming enough to be felt in the fingers after a few seconds. If I was losing voltage at this point then the converter has to run at a higher current to maintain correct output voltage .. so this may explain E2 errors at higher watts..

Hey guys!

I'm getting my provari in a day or two. Bought it from this guy on a different forum, with a one week return policy. He said that his Provari is super picky about the atomizers it accepts. He's not been able to get the low resistance attys/cartos to work, getting the E1's and E2's. I was just wondering if the magnet thing would work. I have no idea what it actually does, my only knowledge about electricity is based on one physics course in high school. Was wondering if a small strip on magnetic tape on the negative end of the battery would do the trick?
Do you guys think that the Provari in question is a faulty one, and should be sent back to provape for a repair? It works fine on the normal and high resistance attys but does not accept any lr-attys. Thank you guys for helping.

I wrote that post before the spring upgrade. I got hold of a dozen of the new springs last thursday and have been distributing them to the aussie provari community.Feedback so far is very good, I can no longer feel the back end of the provari warming up at all.
I gave up on the magnet long ago, for the last few months I had a second spring coiled over the original which dropped resistance a bit but not as much as the new spring, not tested it yet.
Ignore the magnet comments I made months ago .. get hold of the new upgraded spring from provape for $1.25 or so .. you can't go wrong.

 

[vanttila]

Got to try one out. Thanks mate!

Edit: Ah ....., the minimum shipping rate from provape to finland is 20 bucks. That's a bit too much for a 1.25usd spring. Any idea, if some other kinda spring would work? If i find different springs to try, what do i have to take into consideration?

would this work? http://www.ivapour-elixir.co.uk/catalog/product/view/id/270/s/silver-bullet-hot-spring/category/93/

I have a first run Provari... it is said not to have the issue of early blinking.
I haven't really tested it with the spring ( i got one with the Provari Power batt to beta) for LR use yet, but i did notice that the batt discharge blinking is even better;
it used to blink at 3.5 and now it blinks at 3.3 or 3.2.

Visually and to touch, the new spring looks bigger and thicker.

I just ordered my provari online and it was actually shipped last wed unfortunately I haven't received it yet. when I checked it through usps it's still sitting in WA.. I thought priority shipping normally takes around 2-3 days.. did anyone of you experienced some delay with usps? I can't wait to get a hold of my provari..

 

[ukeman]

Bet it shows up today or tomorrow... just not tracking everything... happens all the time

I hope your right ukeman... fingers crossed

 

[Rye]

you were right ukeman, just got an update that it's on it's way... finally..

 

[iBANKAI]

got my provari which bought off the classifieds..and i gotta say..i love this pv..its friggin amazing..work like a beast..built like one too..super happy with it..

Before I wreck my new spring, what's the best way to get it in so it sits properly?

PS: Uke- far as I can tell they are different materials- the new one is a bit shinier.....
I may be wrong and chances are your meter won't go this low (hard to check - maybe someone can verify), but it looks like the old one had a resistance of around .12 ohms and the new one comes in around .08 ohms.

 

[ukeman]

You know me jimho, all thumbs...
i just kept at it with a nail file plastic handle; about 1.5 to 2 mm wide... pressing... was about to give up.... when i got it!
- bet you got it already...
.08 resistance? what does that do?

of course- I used a pair of long needle nose pliers and a little flat bladed screw driver - ...
why does the spring matter? ...

Remember a while back we had a discussion about efficiency of a certain wooden box and I showed how the difference between 12 inches of 20Ga and 22Ga wire could a small but noticable difference?

1) Let's say you're pulling 3 amps from the battery- that wire is costing you I²*R or about 1Watt (9*.12) for the 0.12 ohm spring and 0.7 Watts (9*.08) for the .08 ohm spring.
2) we've been told that the device is sensitive to the internal resistance of the battery- the resistance from the spring gets added into the total reistance that the device sees- I'm not saying it's that sensitive but it could concievably make a difference in detecting the low battery- perhaps that's why some people reported better results with magnets replacing the spring- (not recommended- the spring provides a mechanical function)

Hi getting a provari from my friend with variable voltage wanted to order some stuff for it from gotvapes. but need help understanding the ohms and which ones to get heard u want something like 3.0ohm. need some help understanding the difference with ohms thanks.
