has it be mentioned anywhere regards the push button specs? like life cycle, rate and stuff like that. cos we're going to be clicking on it a lil more to adjust voltage besides only firing the atty.
number 2958 here. whats yours?

Its rated for 400,000 presses. This is also covered under the warranty :)
 
Looking for advice on bats. Currently using Ego with cisco 305 addy. I vape all day at work and go through the reg battery twice( recharge) and one mega battery throughout the day. Are two 18500 bats enough - without needing to carry a charger around- or should I spring for the extension piece and bigger bat? On the verge of ordering my first mod and shipping to Canada is not free. Trying to get it right before I put in my order and get in line!

Go for it,,, (order the extension) you never know a year from now an 18650 may hold 4000 mAh.

Go with Gummy's suggestion. That way you have both battery options available. If its going to be a long day you can swap in the larger battery and use the smaller one for days around the house.

Its only like 18 bucks more I think and I think if you order it with the provari it may be free shipping...

Yeah thanks, all I was looking for was a good reason to buy it and you provided that reason. That does make sense thanks. Anyway to get the Provari pictures beside a marker to see how it compares. First mod so visuals really help.

Hey all ive been looking at the provari for days now lol.

HAve a few things to ask? When will the preorder stop and What kind of battery life do you think it will get with a 18650 aw high drain not sure if you know that or not. But congrats on making a change in the PV world something noone else has and i love the part no screw to turn wooooT!!!!! think i might order mine in the next few days

Hey Mark,

Great question.

It’s got excellent battery life. Here are some estimates.

While these will vary by user (some people will use it more, some less per hour and some take longer drags or shorter drags, etc... These are just estimates based on the mAh of the battery, element resistance, voltage to the element and efficiency of the converter. Once those 4 items are calculated we get a total run time in minutes (as if the button was held down constantly). We then calculate the constant run time and figure out about how many times a minute the average user will take a puff. There’s also some fluctuation in there because the battery will recover a little in-between puffs.

Well just figure in the average user, unless all of you are heavy vaporers? :p


The base ProVari can take a 18490 AW 1100 mAh cell.
Just for a sample, let's say we are using a 3ohm element at 4.2 volts - This comes out to about 12.68 hours.
3ohms at 4.5volts = 11.84 hours
3ohms at 4.8volts = 11.10 hours
3 ohms at 5.2volts = 10.24 hours
And if we crank it all the way up to 6.0volts (3 ohms) = 8.88 hours

On the other side, if you turn it down to 3.3volts = 16.15 hours

These will of course change depending on the resistance of the element. Lower resistance = less time. Higher resistance = more time.

Just for comparison, let’s swap in the big daddy 18650 that you can also use with the extension cap. This AW cell is a 1600 mAh.

3ohm at 4.2 volts = 18.45 hours.
3ohms at 4.5volts = 17.22 hours
3ohms at 4.8volts = 16.15 hours
3 ohms at 5.2volts = 14.90 hours
3 ohms at 6.0volts = 12.92 hours
And the 3.3volts on this one is 23.49 hours

The efficiency of our converter is running 95%, so very little energy is lost.

I know when most of you first get the device, your going to be on it constantly so maybe I need to redo the chart :)

First week with the ProVari – (HEAVY use)
Second week with the ProVari (HEAVY use)

Hey All,

We have been getting some questions about the differences between a non IMR battery and the high drain in the ProVari and we thought it would help to explain why we are recommending you use the high drain battery with the ProVari. In a nutshell, non-IMR batteries can't flow energy enough for the conversion circuitry in the ProVari. Even though a 18650 battery has a higher capacity and amperage capability its more about the internal resistance of the battery.

You can use non-IMR batteries in the ProVari, but since the conversion circuitry might become power starved, it might think it's dealing with a dying battery and turn off. The unit was designed around the high drain cells and we recommend using these.

For those who want more technical details:

The main reason to use the high drain cells is the low internal resistance of the high drain batteries will allow the Buck-Boost converter in the ProVari to operate properly and give optimum performance over the battery charge cycle. When this internal resistance is low the battery terminal voltage will be maintained in the presence of the high pulse in rush currents that the Buck-Boost converter needs to pump the output voltage up. The high drain batteries normally have an internal resistance of 20 milliohms. A non-high drain battery can have an internal resistance of 80 to 100 milliohms. The higher internal resistance battery when used with the ProVari Buck-Boost converter can cause excessive heat build up in the battery and a low battery terminal voltage that may result in the ProVari shutting itself down. It will think the battery is at the end of its charge state. This could cause the user to think there is something wrong with the ProVari when there is not. It should also be noted that this internal resistance will become higher as a battery ages. So the condition discussed could be even worse with a well used battery. Laboratory measurements have confirmed the above. Because of the above analysis, observations, and laboratory measurements we recommend using the high drain for best performance.

I'm 2913 baby!
I an not yet a VV fan, but staying ahead of the curve for me..
I was hoping to use my 18650s, but will go and secure some AW 18550 and 18650 hi drains.. i assume they will fit in the pila charger too.
Any tips on best deals?
Just get them shipped with your Provari- If Dave dosen't have them as we get close to the release date, we'll do a mini coop or two from lighthound.

Edit: And yes, of course they'll fit the Pila charger- you may need a spacer for the 18500..
