I have read of 3 instances of CR2's failiing. In one case, it was reported that they were South Summit CR2's and in another case, they were Blue CR2's that were obtained off ebay (no brand name on them) and in the third case, i do not know what brand they were. I was told that there have been no reported failures with the Green UltraFire Brand, however i cannot confirm that and regardless, due to the possibility of CR2's failing, I strongly recommend against the use of any CR2's in my device or any other device for that matter.

The Super6 takes a 14500 protected battery and the old T1 takes a protected 16340 and that is what I recommend being used in them.

There are some protected Cr2's just coming onto the market and i am going to look into the possibility of reaming the S6 out in order to accept these as they are very tight fit. I will keep you posted.

Best regards,

David

You have to be kidding me! The products selling point for me was 6 volt vaping and now you say it does not have that capability? I am sorry but that should be on your website and it should not be marketed as a dual volt product. Now I am going to get a $160 3.7 volt product? How are you going to address this?

For liability reasons David cannot recommend people to use unprotected batteries. The first time someone gets injured/killed from an explosion (probably due to user error) he is likely to get sued out the ....

If you want to use 6volts, use the green Ultrafires at your own risk. I and MANY other people do and have used them with absolutely no problems. David has to follow the old CYA rule and recommend against using them.

FWIW, I shorted one of the green UltraFires out on a broken mag mod once and all it did was leak rather than explode. I believe (not 100% sure, and not willing to risk a lawsuit) that these are made to vent rather than explode if something does go wrong.

I thought that's what the vent holes on the S6 were for ? if batteries failed/vented.

Do the vent holes not work as intended with the CR2's ?

I have placed an order recently (C.Schultz) for an S6, will I be receiving the reamed version, and if so which protected CR2's should I be ordering ?

I've already ordered green ultrafire CR2's in anticipation but I have other uses for them when they show up. To be honest, I'd rather use protected CR2's if I have a choice.

You may want to revise your Product Detail/Video page;

"The Super-Six runs at dual voltages. The Super-Six utilizes one 14500 protected 3.7 volt battery for 3.7 volt vaping, which is what most all imported electronic cigarettes operate at. For those desiring more throat hit, the Super Six also accepts two 3 volt CR2 (aka 15270) batteries for vaping at six volts!"

I hope you know this information has been out for over a month. The CR2's are having problems.
First, there is just now a protected battery but they are longer that the cr2s that were used in most 14500 mods. This is very new.
Second, there have been new reports of mods that have shorted batteries. This has resulted in many suppliers sugesting you only use 3.7v batteries.

It is better to be informed about what can happen then one day having a problem. Of the cases that I have heard of many were about the Lifpo4 batteries that were "safe". I have not read about the unbranded ones but I can see that being a problem also. Also remember there are warnings on the cr2s about the use in a flashlight. In case you are wondering our pvs act like a flash light.
So now you can do what you want. Use the Cr2s with the knowledge of what could happen, or go place it on the classifieds. I am sure you would get your money back. Many people buy because there is no wait time.

Your choice.

I would listen to David's advice.

Some guy had CR2's explode in his BB, and it broke his jaw and some teeth:
Battery explosion in my mod breaks jaw and knocks out my two front teeth

The Detonator guy also burned his leg:

Grim Green admits to a near accident in a video review:

So unless you hate your body parts, I wouldn't use these things. Stick to RCR123A LiFePo4 batteries. They won't fit your 14500 mod, but you'll spare yourself from injury.

Is it CR2s in particular, or the use of TWO batteries in a PV? The cases highlighted were CR2s, but that was the size the devices took. I have a suspicion that the use of two lithium batteries and the associated matching/charging issues may be at the heart of the problem?

(This is academic to me because I bought my S6 to use at 3.7v - when the wretched courier tries to deliver it at a time when someone is home that is ;) )

IMO (only an opinion) it's probably user error (coupled with crappy batteries/poor quality control) in all cases.

The mod makers just don't want to be held liable when someone blows their face off. If your mod is acting weird, not firing, feeling too hot, the batteries aren't holding a charge, etc... STOP USING IT!

You act as if you were the only one who bought the SS for the 6V vape option....Well i hate to break the news to you mrtuna....I bought one as well... So did 3 of my friends....And last but not least 2 of my family members bought them too....And on top off all that, probably everyone on this forum...To make my point, i will keep it short....When Dave built the SS there was no known problems with the cr2 batts at all....And since David is not a fortune teller,he could not have predicted the future,that some day these batts are going to blow up in someones face....

PS This is not a personnel attack on you mrtuna... So please, do not take this post response in the wrong way....I am just stating facts....
Thanks redrhino...

I don't have a problem with disclaimers for problems caused by stupid us like poking youself in the eye or dropping it in a fire. I have a high tech flashlight that tkaes 2 cr2s and nowhere does it say we strongly recommend you don't turn it on. You have to see the hypocracy in that. If it is advertised as 6 volt it should run safely as 6 volt. If there is a patricular battery that is safe let us know. The problem is the warning is for all cr2 batteries.

mrtuna I do see your point....But cr2's batts were not manufactured by David...All David did is, use cr2's measurements to make the smallest device possible to utilize cr2's for a 6V vape....I do understand your concern....But please think out side the box for a moment...Dave did not manufacture the batts....All he did is, use them in his device, just like the BB manufacturer did, and a lot of other PV's out there use the same batts...Just like the flashlight that you are referring too...If your cr2's blow up in your face, while you are using the flashlight....Is it the flashlight manufacturers fault? or is it the batts manufacturers fault? I hope I'm making sense here...
