ProVari Variable Voltage Mod

[Vaporologist]

Exactly right.... as long as you don't hit the overload current limit.

If I'm understanding this correctly, the cutoff is set at 2.5A. So, if I'm using a 1.5 ohm atty, I will not be able to use the Provari with voltage set higher than 3.75V. Would it be correct to assume that Provari really shines with, and is made for atties at/or above 2.0 ohm for somene who prefers to be in a 10W+ range?

I'm also a little unclear on why the cutoff (E2) is set at 2.5A since AW 18650 High Drain batt has a continuous max discharge rate of over 4A. Thanks.

When I tested the beta units, I went over 2.5A without cut off, but the programming has changed since. ProVape or Kenny might want to elaborate, but you are less likely to hit either current overload or thermal overload with higher attys. You'll find 10W+ is pretty hot and you might see more E1's at that level depending on your boost. I'm not sure but I suspect the current limit may be related to the amount of boost... Also, fwiw, there's some empirical evidence from a few of us that there's a tendency to use a bit less power when using HV atties - i.e. 10W with a 1.5 atty might equate to 9W with a 3.5 Atty. So yes, most of us are finding sweet spots using 2 ohm and up....

It's related to limitations of the voltage regulator (boost, current, power, temperature are all interrelated), not the battery.

good insight...
I've been told the higher the Ohm resistance, with sufficient power the vape gets better.

Due to more durable internal materials, the higher resistance attys should last longer too?

my favorite atty w/my Vari's is a reg. 901 (2.8 to 3.0 Ohm). set at 4.2 to 4.6 v.

replying to my own post ...lol ... how's that?

given the atty resistance and the power setting, how much does PG/VG ratio affect the vape? I sense that more VG tends to burn the juice (taste) sooner, meaning less power is required... but that could affect the vapor production (less power, less vapor).

hey jimho, if i"m correct, what is the ideal PG/VG ratio for taste and vapor...iyho ?

I think you are correct, but I also think it's really a personal thing..... might also have something to do with me dropping voltage down a bit- I tend to stay around 50%-60%VG now that I'm 100% DIY - but when I started out it was 100%PG and only bought pre-mixed flavors....

Some people care more about taste , others TH, others focus on vapor..... some people don't like the taste that VG imparts - might be why some flavors just don't seem to work for me... it also depends if you lean towards tobacco, coffee, confectionary, or fruit flavors. When I started mixing, I started with 20% VG and started adding more till it started to visibly reduce the vapor.... EDIT: SCRATCH THAT- I think VG produces more vapor, PG more throat hit......haven't messed with PG/VG ratios that much since.... may be a good question for the guys over in the DIY section....

 

[crackbag]

i personally mix 70/30 pg/vg gives a nice stong flavor and a whole lot of vapor! seams when you use 100%vg its really gotta sit for a week to get flavor out of it.. and we all know how hard self control is lol

1+ on aging your juice- I find it takes at least a day to develop and the flavor continues to come out over a few days - I can see letting it sit as long as a week to fully develop. Some mixtures have nothing after a day or two but taste good after a week, and others taste good after a day and just get better.....

Now you got me thinking about dusting off some of those flavors that just didn't work for me when I bought them last summer....

 

[ukeman]

I was just going to ask you for any tips on DIY jimho.
is there a best source of PG, VG, and nic liquid?
I have some nic/vg that tastes musky...
do you add any distilled water/ some kind of alcohol?
what flavorings do you like?

hope this doesn't tip thread over.

[ukeman]

I have heard that PG brings more of the flavor (TH too?).
VG - more vapor.
Do you folks agree that VG burns at lower temp? vs PG (can go higher v)

Thanks, that makes sense, great info. I really do like being around 10W. I'm all about "reckless" TH. My current sweet spot is IKV HV306 atty (3.5ohm) at "6V" with AW LiFePO4 batts which is slightly above the 10W range. That setup is the reason why I didn't pursue the VV route until now since I really couldn't imagine anything else being better. However, lately I'm getting into cartos and some 2.0 ohm atties which are too weak for me at 3.7V yet can't handle 6V. I was just trying understand if Provari will have any limitations in providing desired results. It sounds like as long as I stay with or above 2.0 ohm atties/cartos I will get exactly what I'm looking for. Again, thanks a lot for your help.

 

[RedAlert]

I've been running the same atty as you Ukeman, just closer to the 4.8to5.0v range, and I have to admit, it's pretty damn good!

Vaporologist, my opinions on the subject (and nothing more). I read somewhere that the ProVari was designed for a range but was centered on a 2.2 ohm atty and has the best performance at that resistance and that you'll get the greatest voltage range at that resistance. I don't remember where I read that and I don't know if it was a reliable source.

As to the E2 question. I would guess that it's not to protect the battery nor a limitation of the battery but rather a scheme designed to protect the voltage regulator from over heating and or to protect your atty from popping. You won't need that atty protection like a noob might but protecting the voltage regulator would benefit everyone involved. I can't be sure if it's based on 2.5A or if it's based on watts or both. I know of several switching regulators that monitor both current and wattage as a matter of self preservation. That info might be published somewhere on the ProVari, I don't know. Either way, I like to think that it's protecting against damage to the hardware. My 2 cents (no refunds) and no... not even a tiny little bit of love. <grin> <LOL> <wink>

When it rains, it pours eh? You went from no response to your original question to a flood of folks. I'm sure that with all of the love between us........... we all love you a little bit.

They're good questions. Maybe ProVape will chime in with the real poop on these questions. Inquiring minds want to know.

On the other hand, my Wife and I have 8 DIY liquids. Most are in the 90-100 percent VG range. One is 100 percent PG. Most are around 40 percent flavor. Of all 8 flavors and 2.2 ohm atties, the highest voltage/eliquid value for us is 4.8V on a VG caramelish flavor. Most are great (for us) around 4.3V. Everything we have, liquid wise tastes burnt above 4.8V. Some taste burnt above 4.4V so we've never gotten an E2 as a result. We're using all eGo-T's if it matters.

Of course all of this is very subjective. Right? Everyone can't like Cherry and everyone can't like 1.7ohms or 3.5ohms and everyone can't like PG etc etc etc. You've certainly been around long enough to know. I'm just trying to ..... reduce your worries, I guess. I can't know what all you plan on throwing at the thing. For all I know, you could be Dr. FrankenVaporologistStein. <giggle>

There isn't one thing out there that seems to make everyone happy but I like to think that the ProVari gives a person enough room to find a way to love it.

I know it's a Loooooong wait and it's hard to find things to do to kill time. I've been through it. Maybe reading my short little note here will help waste some of your time. If you haven't noticed, I'm trying to distract you.

So, vaporologist, how's the weather treating you there?

Hope I've done more help than harm.

I love 3.5 306's (when I can get them) - I use them on the Phidias with stacked Tenergy LiFePO4's, and at 5.5-5.8V on the ProVari. You'll be fine with them even at full 6V and it will be hotter than your mechanical device because you are isolated from the battery fluctuations.

 

[ukeman]

yeah, and I'm all about taste, not TH... 901 seems to handle a lot of juice and a slightly cooler vape than the 510... you can really pull (draw) on them when you want to, and no backwash.. I like SLB reg. 901's for price, light and profile... the Ikens feel heavy to me...
Value Vapor has good prices. but for HV, I don't want to go up to much over 4 Ohm... they don't carry 3.5 to 4.0 Ohm 901's.

I have been keeping my voltage as close to the low side just because i think my high VG ratio requires it for optimal flavor, but i will go up if needed.

I've been running the same atty as you Ukeman, just closer to the 4.8to5.0v range, and I have to admit, it's pretty damn good!

........ Snipped........

Ahhh, don't try to fight it. That does look like a LOT of love! And you are too funny...

I really appreciate the information you shared. Protecting the voltage regulator instead of the battery with the 2.5A cutoff makes a lot of sense. As you can tell, my knowledge of electronics is next to minimum. Thanks for attempting to help me change that.

I completely agree that everything in vaping is subjective. The same person is capable of giving a completely different advice at different stages of their vaping experience. While many of us are looking for "plumes of vapor", many of us could care less about what we see and instead concentrate on what we feel. My vaping habits have dramatically changed and evolved in the past 13 months. I used to chain-vape 6-8 mls of any tobacco liquid per day and wanted to see a lot of vapor with 7-8 second drags where now I'm taking 3-4 seconds drags every 15-20 minutes and using less than 2mls of fruity liquids per day with as little vapor as possible.

I can totally see how, in combination with other appropriate components, Provari is capable of giving everyone what they need in their quest for PureBlissVaping!

Geez, now I'm even more anxious to try it! I'll probably have to take a 3-week sleeping pill until my Provari arrives.

One more question before I go into hibernation. I've decided to go with the AW IMR 18490/18500 battery for a more compact setup. How many mls of liquid can I expect to go through with a 3.5 ohm atty and Provari set at 6V?

 

[ukeman]

the 2.2 Ohm atty range is evident in the graph that Provape has for voltages/watts/ resistance and i believe battery Mah ....
You can find it on the Provari site page i believe there's a link to it.

jimho, from your input I deduce that any atty from 3.5 Ohm up, may have trouble finding sufficient power from the Vari; ymmv of course depending on how hot one wants it...

not to mention that many so called 3.7 pv's recommend using a 901 atty which is often 3.0 Ohm in regular; implying one may be fine with a 901 HV 4.5 Ohm and up .

 

[rchriste]

I can die in peace now cause I've heard everything. I never thought I'd meet a tobacco person that converted to fruity flavors. Until today, my experience reading has been either/or on tobacco/fruity. With one exception being people adding fruity flavors to their tobacco flavors. You know, like tobacco-cherry... stuff like that.

I got that too... the part about vapor. I don't care about vapor anymore like in the beginning. Surprisingly, I don't care about throat hit anymore either. Which is a good thing for my wife and I cause we're both down to all 2mg liquids now. For us, it's pretty much all about the flavor and going through the motions at this point. That wasn't true for us in the beginning. For us now it's almost like eating candy but without the calories. Actually, she has 1 flavor at 0mg so she'll probably beat me to all 0mg.

I still don't love you but can't we just be friends? <snicker>

PS I prefer to use the short batts on the go and the long ones at home. If I had to choose just one kind, I'd pick the short ones and have 3 of them. One in the machine, one in the charger and one spare in my pocket. I just wish someone made a battery holder for the short ones...... I think you made a good choice. Who cares how long they last if you've got 3 batts. I don't have your atty config so I can't comment on that part but I still think you made a good choice. There is a chart that covers your longevity question on ProVapes website but unfortunately it doesn't refer to the part that matters (ml's per charge) only some hypothetical vaper that vapes who knows how much.......

Now I have a question for you... What's going to be the best way to carry your spare battery? I'm using one of those Walmart matchstick waterproof orange thingy's from sporting goods with a huge wad of foam in the bottom so it doesn't rattle. There are several options out there for the 65mm bats but nothing I can find for the 50/49mm bats. If you find a better way to carry your spare.... let me know. Maybe *THIS* will be a good way for you to get your mind off of waiting.... Find us all the perfect container to carry the spare (short) battery in. Might save you from having to resort to the sleeping pills and that whole hibernation thing.

I have to quit this now or people are going to get the wrong idea about us. TTYL
