The bad thing about the prodigy v2

[2Packsaday]

Thanks for the tip on flavor selection. I have only used 3 flavors in the V2 so far and they all seen very good. I actually have the the cinnamon roll juice coming tomorrow. I will have to try the apple cinn cranberry.

By the way, one thing I did learn is not all KR808 Cartos fit the V2. Although all my Cartos have been purchased from the same company, some threads fit, others don't. About 20% of them do not thread all the way down, such that the center post of the V2 will not make contact with the carto. You know instantly that this is the case when it gets snug after only a half turn.

Pure Smoker told me that there is only one manufactured of these KR8 cartos, so it is simply a thread quality issue. There is no quality issue with the V2, it's built like a tank.

Why is it that Chinese companies have no clue about quality control? I run a manufacturing company and virtually all our components come from China. The trick to get consistent quality components is to buy from American Companies producing there products in American owned and operated factories in China. This seems to be the only way to get good product from those yap-yaps.

Quitter ... A 17670 battery won't fit in the V2. I have 4 of them here, from 2 different manufacturers. The ID of the V2 tube is roughly 16.5mm ... where as the OD of the 17670 is roughly 17.0 - 17.2mm ...

Resistance to the overall circuit of the V2 is added at the contact disk. Aluminum also add about .1 ohms of resistance over your standard Copper/Brass contacts.

Thanks for the info! I got confused because Tenergy lists the RCR123a's we use as 17mm: (and 34.5mm high)

Tenergy LiFePO4 RCR123A 3.0V 750mAh Rechargeable Battery (as low as) $2.79 ea!


Then they list the 17670 also as 17mm: (and 68mm high)

UltraFire 17670 3.7V PROTECTED Li-Ion Rechargeable Battery 1800 mAh CR17670 Lithium Ion

But if you have some 17670's there and say they don't fit I'm not gonna argue. Too bad!

But humour me on this Steve. IF the 17650 did fit, AND we put a copper ring in the switch, it would work as a 3.7 device, right?

Bumping for response

Just found out that VG and 5V don't play together very well. Nasty...

If ya want a V2 to perform like a 3.7v device consider useing one of the 4.5 ohm attys out there. They claim to drop the voltage about 1 volt (I haven't tested this but do have 1 on order) this should make it about 4 volts and no need for any new battery's...

Just pop on the high voltage atty and go.

This might be a nice little option if it works. I will test it when my high voltage atty arrives.

Yes, that is correct

I do not own a V2; however, I vape cartomizers almost exclusively at 6 volts. I think they work great. You just have to keep them very moist. After the initial filling, I generally take between 10-20 drags, drip 6 drops into the battery end, take 10-20 drags, drip 6 drops into battery end……. repeat…repeat…repeat.

Yes, you definitely use more juice at higher voltages; although, I take less drags.

In my experience battery end dripping screws up my carto performance, especially if you overfill. I highly recommend using a drywall screw to pop the cap off (just screw it into the hole and pull - the even pressure from pulling at the center of the cap usually pops it off pretty easily). But you are right - with a high voltage mod or on a passthru you gotta keep it wet!

Pop the cap and direct drip the filler to keep it wet. I use my cartos at high voltage all the time and love it, but I don't even put the cap back on the carto at high voltage, just vape away and keep the filler wet through an open top.

High voltage will burn the carto because you can vape it dry pretty quickly with a good power source.

Odd, I have been using a 50/50 VG cut for my liquids since I got my V2 and love it. Much better than just a straight PG vape. Plus the VG is thicker than the PG liquid so it helps protect the atty a little from over heating.

 

[Quitter]

Yes, that is correct

Steve - thanks for the info! Can I get any of those copper switch rings from you guys? It'd be alot easier than trying to fabricate one to the right size!

 

[NekoGurrl]

Neko - Why are you thinking a 17670 won't work? The length or the diameter?

This was Steve's response back on Dec 12th:

Hey Neko,

We already checked tolerances, and the 17670 won't fit -- atleast from a design standpoint. Once tubes are in Production, we will be able to tell better, but at this point, it doesn't look like it will fit. the RCR123a's are roughly 15-15.5mm, not 17mm.

What I will see is if we can somehow hone the inside (which is already a tight fit) to see if we can perhaps get to 17.5mm on the ID. As it stand, the ID is .665-.675 if my memory serves me correctly. Length of the battery is not the issue, just the OD

Will see what I can do Neko! Really appreciate the PM!

Missed the V2 first production run, so waiting till the next batch.

To tell the truth with the mechanical switch in my Protege I'm really happy right now. It actually seems to do better than my V1 with the 18650 3000mAh battery, maybe the protection circuit in the 18650 limits current flow?

Opps, noticed steve had already posted.

If you really want a 3.7 volt V2

swap out the button for a protege button buy a 14670 battery (lighthound)

hits just like a protege...

 

[JDSupreme]

Any reason I can't run the Tenergy RCR123A 3.0v 900mAh batteries for longer life instead of the 750 mAh ones that come with it?

I think the PureSmokers Ace (KR808D-1) cartomizer vape better at 3.7v anything higher then that will literally cook the juice in the (KR808D-1) cartomizer and will dry up quicker so i've notice. I wish that steve would some how have the option of a 3.7v battery the would fit in the v2 am sure their are others out their who are thinking the same way as me. On certian atomizers like the 510 seem to vape better at 3.7v i think 5v is a little too harsh on the 510 and certain other atomizers that's my opinion..

I just spent about 2 hours testing a HV atty (4.5 Ohm's approx) on my V2and it seems to be about like the first couple of puffs off my stock 510 on a batt just off the charger. This seems to work nicely for the 24 mg juicesand is a cheap and easy way to make my V2 approximate what it would be like with a 3.7 volt battery. But in truth I think I will never be happy with 3.7 volt now that ive been spoiled with true 5v ...

Should only drop the voltage by 1 volt. Should be vaping at about 4.15 volts.

So the verdict is that a 14670 batt WILL fit in the V2 tube?
And the Protege switch is also interchangeable? The diff being a copper contact ring for no voltage drop.

Did I get all this right? And have you done it to prove it all works correctly?

Thanks for weighing in!!

 

[pmgelectronics]

rcc.... how do you know if the 14670 battery (lighthound) will fit the v2. I recenty purchased a protected 3.7v battery from battery junction that had the same dimensions as the rcr123a battery but did not fit anyways. so why do you thing that this 14670 battery will fit.. please let me know thanks..

The14500's fit the V2's. All you need is a small spacer to take up the slack.

The original V1's offered the ability to run different voltages, the Protege is 3.7 only and the V2's are specifically designed for 5v.

 

[rcc]

short answer is yes i have 2 14670 batteries and protege copper ring buttons and I have run a V2 @ both 6v and 3.7v.

6 is what you expect 6v to be and 3.7 is very much like a protege.

And just to be clear...

1) Don't change the whole switch just the button with the ring that holds the spring or wait for Steve to start selling the V2 buttons...

2) A 14670 battery is the same diameter as a 14500 (AA) batt and is a little small for the V2. The V2 does hold it w/o movement but if you do this all the time you might want a sleeve of some kind. Funny thing is there is no mah rating on the 14670 batts I would guess they are somewhere between the 750mah 14500s and the 1600mah 17670s...

very easy and works fine

...the Protege is 3.7 only and the V2's are specifically designed for 5v.

I just want to say I agree with Brock and all I was doing was playing around with the V2. A 3.7 V2 will never replace my protege [insert cold dead hand where needed]...
