Ovale V8 VV discussion!

[Baditude]

My 2 pairs of AW 18350 imr batteries arrived today from RTD. Got them all charged up ready for when my Segelei V8 arrives tomorrow.

Im curious to know how long I can go on two of these batteries before they need changed, too. One would think the combination of two 700 mah batteries would equal 14 hour's use. What charger is everyone using charge these batteries? I had to use two spacers in my Pila, and since I only have two spacers, I had to charge them one at a time.

The other battery that I use are 18650's that my extended Provari and Silver Bullet both share. I plan to reserve the Provari for in home use, and the V8 for outside the home.. Hadn't used the Silver Bullet much since I got the Provari, but having ordered an AGA Tiamet plus rebuildable with my Ovale V8, I plan on using the rebuildable on the Bullet.

So, I anticipate the Pila might stay busy charging 18650's. I might just need to get a dedicated charger for the 18350's. So what's everyone else use?

I use the Xtar WP2 and Xtar WP6 with extra spacers. Charge pretty fast safety features.

Nah - not that simple. That whole volts of choice + device resistance + other stuff. And just the smaller physical size of the batteries is going to mean a shorter relative run time in the big picture.

Well, don't forget you will be getting a dedicated 2 battery 18350 charger in the kit. So you won't be caught short on charging capability. Just a cheapo basic, but it works ok for what it is.

I recently moved on to an xTar WPII 2 charger and that's working fine. But you really need 3 spacers in each channel to keep 18350's in place. So anyone considering that charger make sure you order four extra spacers when purchasing.

Right, I didn't consider all of that.

No charger, I didn't get the kit. I ordered just the body from Discount Vapors before I even heard of the kit deal here.

I'll probably end up getting that Xtar WP2 charger. Thanks for the heads up for getting enough spacers.

I have a Xtar MP2 18350 charger Xtar MP2 dual channel / Dual Voltage Charger - DiscountVapers.com and a Trustfire TR-001 Trustfire TR-001 Dual slot Lithium battery charger. Also the little port-a-charger (which is dual slot) that came with the kit.

One thing I'm noticing right away is, like the VV Gripper, with lower voltages the V8 seems way stronger than expected. That is cool...one of the things I hoped would be the case. I understand that is a feature of the PWM. Another thing is the 510 connection seems much more solid than the VV Gripper, which seems a wee bit weak. I like that the V8 has a metal slotted platform or pedestal with the connection drilled inside it...should be pretty good protection in the event of leaks. I saw the description "recessed" regarding the connection (thus my thinking I'd have to use the 510/eGo adapter) but that is not the case. The metal pedestal with the 510 connection sits so that even a 6ml. tank will sit pretty much flush with the top of the unit.

Only thing I wish is that they'd made the V8 so it'd use a 18650 instead of 2 x 18350s. More like the VV Gripper. I'm pretty sure I'm not going to be getting the charge life I was used to with the VVG. Seems like the 900 mAh batteries that were supplied in the kit lasted just under 6 hours heavy chain vaping. Okay, but not great, I have another set of 700 mAh batteries, and 2 more sets of 700mAhs coming in from MV today (16340 button tops) so I'll be okay. But I'll have to carry quite a few more batteries than I did with the VVG. Not a deal breaker, however!

Question: I noticed that when vaping and the battery level hits around 3.5 that the V8 will sometimes flash a bit right after a puff. That normally would tell me that the battery is getting low with most PVs...but the battery level is still reading 3.5, which, technically shouldn't be "too low". I've carried on vaping until it hits around 3.4v, but was curious. So, I assume, the V8 will NOT give a "Lo" signal when it's time to change? It'll just start "warning" you periodically when the batteries hit 3.5volts (7v on the readout)? Is this right?

 

[josho]

I use an XTAR MP6 charger since I charge both my 18650s and my girlfriend's 14500s (with 3 spacers in each). looks like i'm gonna have to pick up a couple more sets of 18350s and some spacers to keep up. The MP6 is worth its weight in gold though, prime device.

Editing to add a question.. do both the flat top AND button top 18350s work in this?

While not too precise an explanation, there is sort of a difference between the ways the different types of voltage are measured. The Gripper and Ovale V8 measure an 'average' of a fluctuating voltage. The 'Peak' voltage is actually about 1.4 times higher than the readout. When measuring a simple DC voltage from a battery, there is not peak voltage. Anyway, they are sort of different types of voltage. Perhaps another can explain it better.

Another thing is the 510 connection seems much more solid than the VV Gripper, which seems a wee bit weak. I like that the V8 has a metal slotted platform or pedestal with the connection drilled inside it...should be pretty good protection in the event of leaks.

The metal pedestal with the 510 connection sits so that even a 6ml. tank will sit pretty much flush with the top of the unit.

Physics - The larger connector of the Ovale V8 is spread out over a much larger area of plastic. Thus the force on any given area of the housing is substantially less. That's what makes it stronger.

Having 2x voltage, the amperage output of the batteries is more or less cut in half. Given the possibility of high drain/low resistance, I think this is a good thing. I use 800 mAh batteries. 7.4V x 800 mAh = 5.92 Volt-Amps. If using a 1600 mAh 18650, one would have 3.7 x 1600 mAh = 5.92 Volt-Amps. Therefore, the power capacity is about the same and should provide similar life. I like to think the 2 x 18350 is a little better as the current draw on the batteries is lower with the higher voltage source, but I'm not an expert.

I think that is right.

Only button top batteries will work in the Ovale V8.

Um...I'll have to think about that. You inspired me to go look up her pictures on Google. Hmmm. Had read some of her books back when in high school, but really didn't know what she looked like.

Thanks for the explanation. And yes...it really does make sense that larger connector would be more secure than just the little one that is on the VVG. I just got my 4 x 16340 mAh (35mm length button tops) in the mail. Going to charge 'em up and see how they go.

Anyone know where I can get the 1200 mAh button top 18350s that aren't more than 35.5mm?

 

[sonicdsl]

I can't speak to the current version of the V8, but on mine, it will flash "Lo" when the batts need charging. That's when I know to charge them & switch to a fresh pair.

It may be the pose along with the black and white...oh, the haircut and eyes. I may have seen something similar at some time.

Hmmm...best I could come up with. Other shots may have been closer, but couldn't be opened/downloaded.

Ah yes...that's the one I thought you might mean. Well, that's not so bad! lol! I saw some political cartoon type ones that were...um...scary! lol!!

I like the way the 16350s fit in the V8. Much easier. Not that the 18350s are "hard". I'll be buying more batteries next month.

Going to watch for the "Lo" signal this time. The flashing was making me nervous, and I wasn't sure if I should keep vaping, if that was the "lo battery" signal. Or if I was just taking too long hits, or what.

See what I said about the display - at least on the original version - not being calibrated. The display is more of a "rough idea" of the voltage you are actually getting. That's why I wanna know what your voltage meter thingee says versus what the display reads on both models. Curious to know if there will be any big difference.

About the connector: Yeah, the early models had a plain old 510 connector recessed down into the body. I have a version of both and definitely prefer the more solid, non-recessed connector like you have on yours.

Only thing I wish is that they'd made the V8 so it'd use a 18650 instead of 2 x 18350s. More like the VV Gripper.

Yeah, but if they did that then it wouldn't be the cute 'lil V8 we all love! Think about it: If they stuck with the original design and just extended the length of the battery wells to accommodate 18650 it would be this ginormously long, not pocket friendly thing. Any other design mod would make it wider, and probably looking more like a gripper than what it is. Anyhoo, it can't be undone now.

And the run time annoyance will depend on where the V8 fits into your rotation too. Personally, it's not my primary VV device and I seldom use it as an out and about device. But at home I like to use it a lot.

Question: I noticed that when vaping and the battery level hits around 3.5 that the V8 will sometimes flash a bit right after a puff.

What were you saying about chain vaping today? U been doing 15 second drags on this thing? lol If you mean, on occasion, the blue surround on the display is flashing - yeah mine does that too. (If it seems to be doing it, try vaping "button up" so you can see what's going on.) There is supposed to be some built-in cutoff on this thing and mine does that too if I'm taking reallylong drags off it. But if it seems to be a bit too arbitrary try cycling the thing off and back on and see if it improves.

It do have a "Lo" battery indicator that will show on the display for the obvious reason. If your batteries are actually metering around 3.5 volts - yeah, that would do it. It won't shut down on you, but if the batteries are down to 3.5 volts the vape experience will make you want to swap batteries anyway.

 

[wayner123]

I have tried to get it to read the ohms on both of mine from AVT. One of them does nothing but cycles through the volt numbers, and the other one simply read 9.9. How are you guys going about getting the ohms??

 

[Cool_Breeze]

9.9 is an indication that either there is no connection or a short...can't recall which. Maybe the electronics shut down...protection. However, if you are getting a 9.9 reading, that would be the Ohm reading model.

 

[wayner123]

Ok, thanks. I think it must be a connection problem because no matter what I put on it, it won't fire. It lights up, but the connection piece is screwed up. Ehh, it was free, so at least now I have something I can take apart for mod parts, or try my hand at soldering a new connection.

 

[fourthrok]

When it reads 9.9 either there is no cartomizer attached, or there is a bad connection. You get the ohms by pressing the + and the - buttons at exactly the same time. Mine on the rubberized one works fine. There is no ohm meter on the shiny one.

I have NO idea how one would test the voltage under load with a multi meter. The little screw on gizmo I got from MV that reads the voltage will throw an error code on devices with PWM...won't work. I only use the screw on one with my mechanical mods or the eGo T Mod with the unregulated mode set.

 

[wayner123]

Both of the ones I received are rubberized. I suspect that the old one is the one that works properly now. The new one's little post fell out just a little while ago. It may be just that it needs a new connection. Hopefully that's all it is.

I can take a picture if you think that will help.

 

[fourthrok]

Not to be argumentative (haha!) but I thought the V8 was going to be "tiny" from what I saw some people posting. Actually...there is very little difference in size between the VV Gripper and the V8. The V8 is thicker in the middle...but the two devices are about the same height and nearly the same width. The VV Gripper takes the 18650. It fits in my hand just about exactly the same as the V8.

But that doesn't take anything away from the V8! The battery door and 510 connection being more solid are HUGE points that keep the V8 right up there on top of my rotation.

Actually..the Gripper and the V8 ARE my main PVs. I have a 3.7 (mechanical) Gripper also that I use for going out (shopping, etc.) because the cartomizer can be recessed into the body so the it's extremely stealthy. I have some excellent APVs (not near as many as some people...but a few!) I like them, but they are TUBES. And frankly...I'm tired of tubes. I smoked tubes for 43 years. I have plenty of electric cigarettes tubes. Tubes all over the place. Worn out with them. I like the molded "box" mod sort of style. Smaller, easier on my arthritic hands, much better to vape when in bed reading! Won't roll off counters and tables. More classy looking. Won't get knocked over as easily. lol! We all like different things, after all, don't we?

Would like to see a picture Wayner123! "little post"?? Hmm. Yours doesn't have a sort of "platform" connection?
