I'm glad that your ok! I would have crapped my pants. This is another reason why I've always used the VP units. (using both the VP1 and VP2) They all come with protected batteries. They also have LED's but the holes are not just there for pretty looks but rather IN CASE the battery every did crap out. Either way with a protected battery I don't think you have as much to worry about. Modders really need to get on this. There is no point in quiting analogs if we have custom units blowing up in our face
Now that my DX order for CR2's is finally in the 'Packaging' state, I see this thread! Glad you're OK parma. I have a 5v magnum mod I've been waiting to try until the batts get here. Now I'm not so sure....I guess I'd need to drill out some holes in the aluminum casing and the PVC both.
I've been using a FogLog mod w/ 2 Tenergy protected RCR123a's at 6v, maybe I'll finally order a regulator and some buttons and build a 5v nicostick w/ some protected 14500's now...russian roulette doesn't appeal to me very much.

The DX Cr2 batteries are the good ones, they'll be fine as long as there's no short in the unit you have.
Glad you're o.k.
Wow
now i'm really scared...
The other day i noticed the chuck getting hot and i pulled the batteries out ...one was boiling hot and i burnt my thumb.
No explosion though.
They were the green 3 volt batts from Deal extreme.
I have to say we are slightly effed. The tenergy trip and these buggers explode!!

No.. the protected ones just trip.
When this happens one of the two will be fully charged and the other not.
You notice that one has tripped because your vapor goes to zero.
It's the unprotected that could explode...but i think they get hot before exploding.

Better not tell the FDA about this...
They will ban ecigs because of the batts not the nicotine delivery.

When using 2 3v cr2 in series to achieve 6v vape you are using these batteries above there max rated output, If you vape excessively there is a small possibility that they could get hot enough to vent, but highly unlikely. I don't know the facts or variables in Parma's incident but sounds more likely to be a short or a cell mis-match. It would take a bit of vaping to get the batteries hot enough to vent or in Parma's case actually explode and in her case, it doesn't sound like she was vaping excessively at the time. These batteries would get so hot you couldn't touch them before they would actually vent and that would take some seriously heavy vaping. One other possibility is a mis-matched cell, meaning not equally charged. If one cell has a lower charge then the other, then the higher charged cell will begin to charge the lower cell, the lower cell will undergo polarity reversal and will get hot very fast and vent gases. Almost as if you put 1 fully charged and 1 dead battery in the mod.
One other factor that is overlooked in a double battery setup is the current from the rear battery must pass through the front battery to reach the atomizer. I have looked into this and came to the conclusion that a protected cr2 version would most likely not work, being the batteries are used above there output you would more then likely trip the protection circuit in the front battery.

I am pretty sure in this case it was a bad cell. But it is REALLY IMPORTANT for everyone to realize that a bad cell and explosion can happen with ANY battery of ANY brand. My only reason for posting this was just to let everyone know that it is NOT just one person who has suffered battery failure. My only point here was for everyone to realize there is danger and we should all exercise at least minimal caution.

Agreed Parma,
That could have been much worse, glad to see you came out of this with relatively minor damage. People do need to understand the potential hazards when using 2 cells in series and Lithium-Ion batteries in general, protected and unprotected, bad cells are not limited to unprotected versions only but there is a better safety margin. Just to state fact, almost every piece of electronic equipment you hold to and near you face contains a lithium-Ion cell.

It would seem that the spacer/liner would insulate you from the heat, and you might not notice... Glad everyone is OK.
How are you going to drill the holes? I don't think I have the right equipment. Do you think taking them to a machine shop would be a good idea. I have a Prodigy, Protege, SD, and a couple of laser mods. I guess on the SD the holes would have to go in the side. I'm thinking two/three holes in the sides toward the bottom. Any reason why the bottom cap would be a better place to drill?
I'm going to go charge up some 510s.
Another question...
I have a brand-new RCR123A just charged for the first time today. I got a few good puffs from it, then dead as a doornail. Is this a warning sign? After I verify that it is a dead battery, not a dead switch or something, I need to decide whether or not to pitch it. I'm scared to charge it. Yikes!
And Parm, glad to hear you're ok. Thanks for sharing this info with us.

This particular set was in my new rotation. So that means that they were used maybe for 10 draws or so per day and charged at the end of each day for about the last 8 days. I have been running my sets in pairs for 10 days each. This is my 3rd brand new set out of a total of 8 sets. Is that what you needed to know?
Did you check your atty? Sounds like you blew it out with 6v.
Id check to see if its working on another pv if you can.
