The Precious PV's

[KEITH97M3]

Hoosier, I feel your pain of waiting man, the Romanian post office ships it out pretty fast but the same cannot be said for our Customs dept. Also from experience, I really think you should get at least 3 pairs of batteries if you plan to be out all day without a charger. All day meaning for over 8 hours with heavy vaping. My recent tests have shown that the AW IMR 18350's cannot out last the 3ml tank of juice at 5volts. More definite testing on my part needs to be done but I am estimating that they can only last about 1.5ml or so.

I think my auto off timer is set to around 5 minutes and since the led isn't really consuming any power, I would love increasing mine to 15 minutes.

Ps, did everyone's package have any stamps on it saying that it went through Customs? Mine didn't and arrived in 5 days so I was just wondering.

Aloha, Keith

 

[Hoosier]

Dang, I got a good deal on those 18350's. I'll have to see if I can get the same deal again... (Not likely)

I can kill a good 18650 in a 16 hour day, so I imagine I'll need more than three pairs of 16350's.

 

[modistru]

Tomorrow I will test the new 2900 mAh (AW 18650-P) on a 1.8 ohm @ 3.6v. Not expecting to get a whole tank, but will report. The same batt does 3ml juice @ 5.2v/3.2 ohm on a booster mod no problem.

I'm at the same point as you Hoosier... waiting. Wish the tracking was better.
I just noticed we're only five days apart in time we've been vaping.

I have quite a few 18650s and one last all day on v1 and because it's a Precious I'm not as worried about a higher voltage than I am all day without changing, I love that. At the end of the day bat is around 3.9 -- I vape around 3 ml a day. That may go up with the v2 though. This is the way I intend to run mine but I will get some 18350s once you guys shake out the ones to get.
I'll make a cable but I would also have paid an extra $10 for one. Initially we were supposed to get one with the unit... oh well.

Do any of you have problems accidentally turning it off/on due to the double-tap like Keith has talked about? Sounds like it's really frustrating him and I was wondering if anyone else is frustrated because of this.

DC- happens to me all the time. What is more bothersome is accidentally getting into the settings mode, especially when driving. I usually only have problems if I try to use my thumb vice my index finger to fire it. Regardless, I still use mine daily and love the mod. It's really nice to have a 510 atomizer that is tank fed, and at a reasonable size. The whole unit is 1/16" longer/taller then my ProVari with the 18650 in it.

Filled it this morning and have been using it off and on all day (I can't stealth with it in the lab, so use a 510 for that). I have 3 sets of 18350s from my SDMKII days and have been using them. I would think they are a little long in the tooth though, as they are over a year old!!! When I start seeing the orange led, I start thinking about changing them out.

BTW, mine came the day after USPS updated tracking on it. One day it was awaiting shipment from Ro. and the next it was at my PO.

Looks like C. would have realized that considering the length of time he played with it. That's why I asked. Though maybe it was just Keith's technique.
This is something that cannot be changed by the way.

The thing is that dry thumb syndrome will accidentally double click it or push it into menu. If you have no trouble with the Lv1, you will be mostly OK with the Lv2. I tend to keep it light side up for easier glance down checking for entering off/menu. It helps for checking if it hit the timeout too. You say $4it and click appropriately to get it back. Happens to me ~5% of the time. The extended/rounded firing pin is a major improvement.

ETA: most misfires are due to the timeout, forgetting to turn it on first.

 

[datacreek]

Well that's good to hear because I've never had a problem with dry finger syndrome on the v1. I've got several laptops and one has a touchpad that is so slick it is hard to use so I'll sometime douse my hand with some talcum powder... even with that my v1 fires every time.

Yeah, the new button sounds great. What I was worried about is with the v1 I'll sometime be moving my finger around to find the button and will find it then I'll fire it... kinda like touching it twice, which would turn off the v1. With the new button I'll learn (hopefully) to move my finger and not lift it once I find the button.

The cable will solve the timeout issue as we can increase that.

I'm still waiting... will post my experiences when I get it. Hopefully by Sat but it may be next week.

Love to hear your feedback DC! I'll post how the LR/2900 mAh experiment goes. It was too late tonight to attempt to vape 3ml's . The new batt chemistry works nice on a booster mod, but the Precious's other battery option will hopefully be good info. The AW 1600 mAh/LR 510 does not last a full tank for me.

 

[KEITH97M3]

Yay!! The extended sticking out sensor was my request to Caesar and actually I wouldn't have minded if it stuck out even more. It does help to stop the damn dreaded "table roll off" and you can feel it without looking.

Still testing to see how many ml of juice I can vape before the AW IMR 18350's go dead. Right now the led just changed from green to amber so it shouldn't be much longer. Will let you guys know how long it lasted at 5volts with a LR 1.5ohm atty.

Aloha, Keith

 

[JollyRogers]

Good gawd man. 5v w/ a LR atty!!! Now wonder you are getting nic stupors I am running 2Ω @ 4.1vdc and find mine pretty near perfect.

 

[Big Hitter]

at 5volts with a LR 1.5ohm atty.

Yikes ..........

 

[KEITH97M3]

I actually did this by accident but found that a LR 306 on 5volts is not bad and puts out plumes of vapor like a nuclear reactor melting down. Originally I had a standard ohm Joye on it and forgot to lower the voltage when I swapped out the LR.

Ran those tests yesterday and through last night and this is what I found.

Filled juice dispenser to the max with Boba's Bounty 100% VG with a pair of fresh off the charger AW IMR 18350 batteries. Vaped till about the last 20% remained till the batteries could fire the atty no more. Atty used was a LR 1.5ohm 306 with the Precious set at 5volts which I confirmed using a voltmeter. When the atty could no longer fire, I took them out and checked them with the voltmeter, voltage was down to about 2.44volts each which is considered 100% dead because the max low is rated at 2.5volts.

Total time till batteries died was about 8 hours but this is not an accurate measurement of battery life when not everyone will vape the same amount. Today I vaped less than I usually do, barely using 2.5ml during the 8 hour period. Liquid consumption with known voltage settings and atomizer ohms is a much better assessment. That way people can judge how long the battery lasts by the amount of juice used.

Not sure if the amount that the Juice dispenser holds is exactly 3ml but there was only about 20% left over when the battery finally died. I sucked up the remaining liquid from the bottom collector and placed it back into the JD before estimating the remainder. Hard to measure exact ml because all my syringes have no numbers left on them from the juice eating them away. Will repeat this test again using the standard 2.3ohm Joye atty and see if there is much of a difference.

Hopes this helps give people an estimate of what to expect with the AW IMR's. Hard to go back to 3.7volts now as that feels so wimpy after using 5volts.

Aloha, Keith

And to follow Keith's informative post, here is what I found using an AW 18650-P 2900 mAh (new chemistry) today.

I put a freshly Pila charged batt into the Lv2 with a 1.8 ohm atty and 3ml of juice in the tank.

9:00am: Set the device to 3.6v. For the first couple of hours it vaped OK. A little light on the vapor, but usable.
Noon: Started having to pull for 8 seconds to get a good drag.
3:00pm: Bumped the tenths setting by 1, continued the 8 second drag for meh vapor.
5:00pm: Tank empty. Never reported amber (except for the warning - long drag!)
6:00pm: Voltage on the cell measured 3.85 volts. Not bad... it could have gone longer.

All in all, the new battery does last a long time. However, I do get much better vapor production (with the same atty) driven straight up.

For the Lv2, AW Reds work better should you want to run it @ 3.7v. Just remember to carry an extra one. Personally, I'll be using stacked AW 18350's with Keith

 

[datacreek]

Quick question: Are you guys measuring or have you measured with a meter? I know the polarity is reversed but seems like I read somewhere, maybe this thread, that if you accidentally touch the side of the atty (shorting) that you could damage the device.

 

[modistru]

DC, according to the information available short protection is built-in. I just don't think anyone is willng to test that feature on their new device
Since a cable is needed for PC connection, getting a male 510 wired ahead of time solves two purposes. Safer/easier measuring for now and getting half of the cable work done for later

 

[Hoosier]

Limbo is over... Kinda'...

Received call that it had arrived, but I'm still at work. Then have to rush home, grab son, and attend a BSA function for a few hours where I'm officiating.

Reminds me of Christmas when I was young and we visited 4 different relatives' homes the day of every year. Open, pack, rush off, leave play for another day...

I'd better be happy dammit.

Do any of you have a test connector that you can use to stick a meter between your atty and the Precious? 1.5 ohms and 5V is 16.66W and 3.3A of current- not sure what Caesar said the capacity would be but that's kind of high. I may be wrong, but I suspect he might have programmed something to limit the output in an overload situation or his chip does it automatically. If he didn't you'd be frying those attys or the chip pretty quickly.

Jim, I don't have one of those inline meters, I am just using my multimeter to read unloaded voltage. I measured the ohms on my 306 LR and they are 1.5-1.6. The unloaded voltage on the Precious is 5volts and you are correct about the watts being 16.66. You already know that I am using the AW IMR 18350's and that they are capable of higher amps so I am not sure why this combo works best for me. I only did this by accident when I forgot to lower the voltage setting after removing the standard 2.3 ohm Joye atty that was on it before.

I tried this same atty at lower voltages, it worked well with tons of vapor but lacked the heat that I enjoy. If the chip burns out then it burns out. He did make this to be capable of going up to 8.4volts so I am not going to worry about it. Make no mistake about it, the heat produced is high but with the stock plastic tip, I cannot really feel it on my lips but damn do I feel it in the vapor.

Aloha, Keith

Got it and man does it feel light compared to what we're (v1 users) used to.
The button on mine does not seem that much different than the v1.
I may need some help/tips. JD does not appear to be working. Unit vapes great but after the 7 or 8 drops I initially drip into the well are gone I'm not getting anything or very little. Unscrew the JD and the well is empty. I cleaned the JD then cleaned again and ran a guitar string through the hole in the JD to make sure it wasn't clogged with anything. Washed again. Works great until the juice in the well is gone.
I'm using a 510 with 60% VG. I know several of you are using at least that much vg or more so I'm perplexed.
I'll even give it a few unpowered tugs and that's not even helping (I don't think)... I've only had it a few hours.

I used an unwound guitar string to check the hole but I was thinking I might use a wound string to waller the hole and make the diameter a bit larger but I consider that drastic at this point so I'm waiting to see if anyone can tell me something that might help.
