ok, so i'm getting pretty ...... off here... first off, i'm basically out of my 'good' carto's and am waiting on my order to come in, so i'm having to use my ....ty leftovers from my initial purchase a long time ago... basically mostly LR cartos and a couple of higher res dc cartos that don't wick and taste burnt and ....ty all of the time

my problem is when i use anything lower than 1.9 ohms, i get E1 and E2 errors, consistently and constantly. I have one carto that tastes good, so i started using it today. when i started the day it said it was at 1.6 ohms, great, i set at 4.2 volts and it worked good for a bit. this should give me 11.025 watts (well below the 14.5 watt max of the v2 provari). well, i got an error (e1 or e2, i don't remember, but its random it seems) so i lowered the voltage and checked the res, it was down to 1.4 ohms, had to lower the voltage to 4.0 which should give me 11.43 watts, and it errored out within 2 minutes. checked again and was still at 1.4 ohms. had to lower it to 3.8 volts and it worked for another few hours. this is 10.31 watts.

then it errored again, so i checked and it was down to 1.2 ohms, so i lowered it to like 3.5 volts, and it's basically gone down from there, and now it's showing its 1.0 ohms and erroring out at 2.9 volts, so i can't even use the carto anymore... and it's my last decent tasting one. even at 1 ohm, i should be able to run this at 3.5 volts (which would hit the current limit of 3.5 amps) and would give me 12.25 watts... there is NO reason why i should be getting an error at 2.9 volts... so wtf?

i contacted provape and they told me simply that i should clean the contacts with alcohol and it should fix it.... no such luck (obviously)

i wouldn't be too worried or ...... if this was an isolated situation, but my provari has errored out with every single carto that i've used on it if it is lower than 1.9 ohms. most of the time the resistance doesn't go down like it did with this one, but when i calculate the power and current, i am WELL below the limit. for example, if my carto is 1.7 ohms at it's lowest (like right after using it, when it's cold it's at 1.85 on a meter) i get errors anything above 4.1 volts or so, sometimes as low as 3.9 volts it will error, though usually after using it for a little while, though the provari still shows 1.7 ohms on the carto

so what gives? seriously? and thanks for reading it all... sorry for the long post, i'm just mad/confused/frustrated

thanks for any help or suggestions or ideas.... i appreciate everything and anything you can offer me

Keep in contact with Provape on this.

The problem is, you don't have a known "good" carto to verify that it's not just the carto having issues. There's nothing but a thin ring of silicone between the positive center post and the negative sleeve on a carto. There maybe a shorting issue. Your coil ohms shouldn't be all over the place like that either (they fluctuate, yes, but it seems something's amiss with that carto).

Or, the Provari is to blame. Remember that error codes are protecting the device from possible damage, so if it's a bad carto, it's just doing its job, but of course there's always the possibility you have a bad unit. Get some new cartos, though, because you need to eliminate that as a cause.

well i got my order of new cartos and other stuff, and the problem has gotten better, thats for sure. i still do get an error code if i go higher in voltage, but for example i have a 1.5 ohm bridgeless atty and i can push it up to about 13 watts or so, then it errors out, but the taste is gross by then anyways....

i haven't tried a DC at 1.5 ohms yet, but i do imagine that i wouldn't be able to run it properly since it takes more overall wattage to run a DC properly compared to a SC unit

yea, i totally agree that it is super nice that it does that... i just don't want it to kick in the protection TOO early, you know?

that, and i really do wish provari DID NOT make the unit have a variable upper current limit that kept the wattage below about 14.3 watts. it just doesn't make sense to me.... electrically all the unit does is, when the voltage is set high enough that it needs to limit it, it would either error out, or just lower the voltage (i assume the provari errors out instead of lowering it for you though). they state that this is because after 14.3 watts juices burn anyways, but honestly, that may be the case with a single coil unit, but a double, or more applicably, a triple (or even quad???) coil carto/whatever would EASILY draw more than 14.3 watts, heck a triple coil carto at 14.3 watts is only going to give about 4.7646 or so watts to each coil... thats not going to give much of a warm vapor at all. the whole point of the V2 is to allow people more variability with their cartos, and i don't want them to tell me when my juice will burn, if i'm using a provari, i should know enough not to turn up the watts to the point it burns juice, and if the unit has a current limit of 3.5 amps, it really shouldn't have an issue with it regardless the voltage (though i do know that, while in principle that's all fine and dandy, if they didn't design the dc-dc converter with enough headroom, or the batteries can't supply enough current for each pulse of the converter when the current and voltage are near the upper limits, then it wouldn't go high enough, but quite likely it just wouldn't put out the current/voltage, it shouldn't hurt the unit anyways)

sigh... oh well

Krprice84,,, I think the unit is working correctly, just my opinion,,, you said your using older cartos and they could be dropping even further in resistance after you hit the power button an also getting dryer neat the coil because the coil is getting so hot, the 1.4 ohm could be dropping to more like 1.0 ohms after a 2 second vape and then you get the error code because @4V & 1ohm you would be pushing 16W therefore its going into the error field. Try a higher ohm Atty/Carto and see what happens and I bet you the Provari is firing fine. This seems to be a touchy area with the Provari when ohms get down lower then 1.4-1.5 even with the V2 Provari units but they are working correctly by going into the Error field. Just try the new Cartos or higher ohm Atty and see what happens,,,, if not then contact Dave @ Provape but I'm betting whats happening is what I'm saying here,,, same thing has happen to me numerous times on bth of my V2 units.

Read the Provari FAQ: http://www.provape.com/v/faq.htm

In particular, the section titled "Why does the ProVari need to use high drain batteries (the full technical answer)?"

You are simply limited in the amount of amperage you can pull from the battery. Your last sentence is correct: you're running a battery-powered unit, therefore there are limitations on what amperage you can safely draw from the battery. This certainly isn't exclusive to the Provari.

The only devices providing crazy amperage are stacked-battery mods.

I experience Error issues, overload issues and other little quirks on occasion using my MV VV box mod.
**Only when using DC cartos.**
They happen instantly with LR DC carts even at low voltage settings ( Like a 1.25ohm DC cart. Unusable on my VV box)
These voltage problems and things that cause my VV to shut off & LED tweak , go away with SC cartos. ..
( At least my experience )

I avoid LR and/or DC stuff on my VV box mod.. Its seems to be happy that way.
LOL

Peace and Good Luck.

the last line is incorrect...just fyi.... stacking batteries can not supply any more amperage than a single battery can at max output. stacking ONLY increases the output VOLTAGE. if you wanted to supply more currect you would have to set up the two (or more) batteries in parallel, which would keep the voltage at the level of the single battery, but supply additional current.

and i understand why you run into limits at the higher voltages/currents... even though the output current is less than 3.5 amps, the battery is putting out much more than that, as it's voltage is only 3.7volts (nominal) and thus, to put out 3.5 amps at a higher voltage than it's nominal voltage, it will need to supply more current to the boost converter. my issue with the V2 design as compared to the V1 design is that the whole point of the V2 is that it is supposed to allow you to use dual coil/lr cartos/devices at higher voltages. i know that AW and other high current drain batteries can easily supply 10C (or even 20C for some, though not many, units) which means they should be able 16 amps for a 1600mAh 3.7 volt 18650, which is not nearly what is being asked of it at the higher end of the error range. at 6 volts and 3.5 amps it would be pushing 21 watts exactly. that means that the battery, assuming a 90% efficiency of the converter (which provape claims to be 95% or better, though at the high end of the output i'll lower that to 90%), that means that the battery will be pushing 23.3 watts, meaning at a nominal battery voltage of 3.7 volts the battery will need to supply 6.306 amps - this is considerably lower than the 10C rating of AW batteries (only 39.4% of 10C, or about 4C which would be no problem for an AW battery to put out).

thus, the provari isn't limited by the battery output, and with revised firmware, should be able to easily push 3.5 amps at it's 6 volt limit, which would allow us to push dual and triple coil carto's to higher wattage per coil. this may not be an issue with most parts yet, but i'm sure, as is human nature, people are working on bigger and bigger carto's every day. the limiting factor of the provari may, however, be the boost converter, which quite possibly runs into horrible efficiencies at higher current and voltages, and possibly may not even be able to handle 3.5 amps at 6 volts, though i doubt that is truly an issue.

Try this....take battery completely out of the unit for a couple of minutes and reinstall.Once Ive had that happen, this seemed to fix it.You could also try adjusting the voltage down a few notches to see if that helps.Really does sound like a bad carto though.I had the same problem and replacing it with a new carto fixed it for me after trying to "reset" it didnt work.

yea the pulling the battery trick sometimes helped, but i do think it was mostly a bad carto, as well as possibly just good cartos having their resistance change slightly while the unit is on and being used, cuz when the unit tells you the resistance the carto isn't as hot as it would be while vaping, so the resistance isn't going to be the same as what it is when its in use. the odd thing is, most types of wire go up in resistance as their temperature goes up, though i know some has a negative temp coefficient, i kind of don't think that nichrome wire does.... anyone know for sure?

I thought the provari's were limited to 2.5 amps before auto protection gives you E2 error. If this hasn't changed then a LR atty or carto isn't going to work at more than nominal 3.7 volts.(give or take)

The V1 had the limit of 2.5. The V2 has been increased to 3.5 amps. However, the Provari is probably not the best choice for LR cartos. It drives them pretty well but it isn't the best choice for LR cartos. Provape advises the use of SR cartos and given the ability to go as high as 6 volts, the need for LRs is reduced in many cases.
--- From: ProVari Variable Voltage Ecig: Best Variable Voltage E Cig Available! ---



I've found that when you clean the internal contact pin with a Q-tip and alcohol, sometimes gunk gets really embedded on it and it can take some time and elbow grease to get it off. I've read this gunk can build up on battery terminals too...with that said, I imagine you've already checked this.


This video helps illustrate where the V2 should perform with good LR cartos. On a 1.4 ohm carto, the Provari V2 throws a code at 4.7 volts, equating to about 16 watts. I've verified this myself, in which it throws a code around 15-16 watts, give or take. So something is not right with either your unit or the cartos. If the unit is not performing for you on good LR cartos like it is in this video, and the cartos are good, the unit may be 'sick'. From my own experience, while I stated above that the V2 is not the best choice for LR cartos IMO, mine has no trouble driving even crappier ones at power levels that you were having issues at (ones I get on clearance and stuff). Sorry to hear of the issues :( and hope they get fixed.

It's worth noting that even by Provari's OLD resistance-setting chart for the V1's 2.5 AMP limit, you are still hovering around what should not have given you an issue.
