ProVari Variable Voltage Mod

[ukeman]

first, the blinking indicator is a "low batt" and recommended time to change and recharge, which is better for the battery life.
You can keep vaping until the batt loses its charge completely, but not recommended.

depending on how much vaping you are doing, counting hours of use is not helpful; say you vaped once in 24 hours, your batt should last a month.
better to go by juice consumption.

IMR batts don't last as long as Li-ion protected batts anyway. I only get a few hours of hardcore chain vaping.

Check the batt. charge: Cb setting to see for sure from start, and when it starts blinking.

i have another quick question with the provari and the batts..did anybody buy the batteries from the provari site and charge them like normal only to have them "die" just a few hours later??..i charged mine and i used it for a few hours and then the button started blinking rapidly and it was dead,i thought this to be rather strange so i unscrewed the cap took out the battery and then put it back in and it started working again. i know that the provari has protection against this kind of thing so you dont damage the PV or the batteries but does that protection disappear if you reset the pv allowing you to still use what little juice is left in the battery or was my battery never really dead to begin with??

didnt see the last posts, ...
what is the recommended spec for time to recharge ?

Mine is at 3.3v
Everyone that is having the low battery indicator issue, does it still have the blinking with a different battery at the same voltage reading?
If these are issues with this certain batch of device, please pm me or shoot me an email at Ken@provape.com and I will look into this issue.
Thanks,
Ken

I "spoke" to Ken before he posted this. He is extremely customer focused. Kudos to him and ProVape.

Incidentally, for me -- I rotate 5 batteries with the same result.

Mine was shipped on 1/13/2011.

Wouldn't blame you for not wanting to send it back from the UK -- It is important to note that while this blinking notification is annoying it does not stop you from vaping until battery depletion.

Should this issue have been discovered before dispatch? Fair question.

This is the only flaw I've found with the device and the only hiccup from ProVape thus far. I love this thing, it's given me the satisfaction from vaping I've longed for. Your ProVari or your wife -- er,ah.....

Thanks for that Progg so not a big problem then ,that's good

It's funny that the low batt LED is coming up. A few days after I got mine, I emailed them to ask about getting it disabled altogether but that would've meant shipping it back and not having it for a stretch of time. I just wasn't willing to be without it for that long.

You're welcome cliffy. It really is a minor annoyance. It doesn't affect the ProVari's superlative performance .

I know bupkis about the electronics in this PV. I do know a bit about metal -- The threads and all machined surfaces are burr and blemish free.

You might want to take care at the LCD plastic (?) screen. It's not fragile by any means, but it could get scratched up over time.

Overall -- as I said -- your ProVari or your wife? Bye honey -- just kidding.

You're gonna love it.

Yes Ken I actually have this issue with both my beta and my production my beta starts flashing at 3.8 and my production flashes at 3.6 with any of the 3 batteries I have.... I usually just do as I stated b4.... When I reinstall batteries on the beta it will fondown to 3.5 than flash again.... When i reinstall in my production the voltage actually goes up to 3.9 and stops flashing and than drains back down again.... Very strange but not really much of and issue.... I will not b parted with my two lovely provaris

@debb. Hi Hun how are you??

Mine starts flashing at about 3.5 V and then stops working at about 3.3 V. So... is it better for the battery to charge when it starts flashing?

I haven't check prices here in WI lately, but I'm pretty sure they're 'only' over $7USD.....
About 13.50 in NYC.... ughh thank god for PV's

Yes, the government here thinks that raising the prices (and pocketing more taxes), will motivate more people to give up smoking.

I was sloppy in writing battery depletion -- should have said battery discharge.

The ProVari cuts off at discharge. A further explanation of the negative effects of battery depletion for a protected non-IMR battery is here at battery university: How to charge - when to charge table

For the ProVari we use non-protected high drains so depletion isn't an issue.

Not clear what you are saying here- provari cuts off before the battery is fully depleted. It starts flashing before that. IMRs should never be fully depleted, and because they have no protection circutry it is more important that the device does this for you.

Fully depleting an IMR can result in crystalization which causes increased internal resistance and shortents the capacity of the battery.

IMR's have different voltage characteristics- I've seen vendors claim that the battery is fully depleted with a floating volatage of 3.6V and I've seen specs claiming the minimum loaded voltage is 2.5V. I've been seeing the batteries come off the provape at 3.5V (when it won't fire any more) so it's possible we're over discharging.

Regarding the lights- they should be comming on when the battery gets to the point where you should consider charging it- not just before being fully depleted-


Last week I read somewhere that IMRs are suceptable to oxidation on the contacts. I hit mine with some 800 grade sand paper and will try to run some tests this week to see if there's an improvement.

I also rotate through 5 18560s and 4 18490's - bought from different sources at different times- so if any of my batteries are from a bad batch or out of whack, I'll know.

Also, I noticed some differences using the Pila charger over the TR-001 - the TR-001 seems to be giving a better charge- not sure why... I'll try to get some numbers on that as well this week.

thanks for all the info jimho...

oh great...;( I know the TR-001 has a more snug fit.. the 18490's are a loose fit in the Pila.

 

[ukeman]

btw, if you drip and don't want any juice coming up the d/t into your mouth, try the Pyrex glass d/t's from theecigs.com... it's true... juice slides right down and never seems to come back the other way... be careful of the fit though, one i got i guess being hand made didn't fit in the atty properly...

Thank you jimho for more clearly saying what I tried to say. I got myself in deeper than my comprehension of the subject allowed.

Lesson learned.

I would think you wouldn't see any change. Oxidation is a function of the metal used in the end cap, it has nothing to do with battery chemistry or circuitry. Electrical flow between two different metals can cause an electrolytic action - basically an inefficient form of electroplating - but that also has to do with the metals involved, and the fact that there's an electrical flow, it also wouldn't be affected by the chemistry or circuitry of the battery.

Hmmmm.... Just had a thought. With this "low battery indicator issue" and any other software type issues that could possibly arise, wouldn't it be cool to have a small USB port built into on these Provari's so that we could simply download a software update and re-flash our units? Sorta like they do with camera's and trail cams and other software driven devices. That way no one would ever have to send their baby's away. Of course real estate is limited on these guys but it's a thought.
idk.... Provari-II maybe!? lol

 

[nickf41680]

Who knows lol? We are still waiting for an update on the site right???

Hmmmmmmm

Well, it's here. Put on one of Ike's Gold V2 drippies filled with blackberry lemonade from ivape. Tasted like it always does at 3.7. Started dialing up the voltage and when I hit 4.3, the flavor and vapor exploded! Wow. This really is something else... Now I gotta see if my juice is sold by the gallon, cause I have a feeling i'm going to be using more than usual.

Excuse me while I get a nic high on...
