With that said I am going to change the title of the thread.
i just ordered two AW IMR 18490's from Electronic Cigarettes and AW batteries by Super T but i was planning on using them inside a PROVARI -- even though the battery's are not protected Provape.com recommends these battery's and states only this
no were in there does it safe than li-ion and prolly why most li-Ion have protected and unprotected versionsAW's IMR High Drain rechargeable battery chemistry is safer than Li-Ion, offers faster discharge rates, and is better suited for high power applications like in the ProVari
this is why i ordered these for the Provari- i am sure the battery cap has a hole in it in case of "ROUGE" battery's that might explode or expell gass's, and i am almost positive that even though the AW IMR batteries are not protected, that the Provari itself has enough protection circuts in there itself to more than cover me to prevent this from happening.What is the difference between regular and high drain batteries and why do you recommend I use the high drain over a standard 18500/18650 battery?
We recommend only using the IMR High Drain battery in the ProVari. These special batteries are rated to have a higher power output than non-imr batteries. Non-IMR batteries can't flow enough energy for the conversion circuitry in the ProVari. You can use non-IMR batteries in the ProVari, but since the conversion circuitry might become power starved, it might think it's dealing with a dying battery and turn off. The unit was designed to use the high drain batteries and we recommend using these for best performance.
i know not all mods are created equal, i just hope i made a informed decision given the mod that its going into.
About to buy a Provati should I worry about the unprotected battery, is the black color better for finger prints, and 2 or 3 extended batteries <-- was the #1 reason why i decided to get the AW IMR reds
just make sure according to your own mod - the type of battery it uses or recommends -- the protection on batteries needs to be somewhere, and for the provari it is built into the circuits and not the battery

I think I may be able to shed a little light here. It was my girlfriend that this happened to. She had the battery in her Indulgence and the Indulgence in an eye glasses case which was stowed in her coat pocket. There was no atty/carto attached. She went to dinner with some girls that she works with and laid her coat down in the booth next to her. About 30 minutes into dinner there was a loud boom that, "sounded like a gunshot". She ran outside with the coat after the pocket caught fire. Luckily, all of the parts of the Indulgence and battery were just floating around inside the lining of her coat so I could inspect it and take pictures. There was nothing else inside the case with the Indulgence except for a 10ml bottle of juice. She had forgotten her atty in the car (laying in the front passenger seat). Of course, a short in the Indulgence could have led to the explosion, or it was just the battery. I do not know for sure, and am pretty sure there is no way to definitively say. I appreciate the message that oldsoldier is trying to get out, and that is simply that unprotected batteries are just as dangerous as any other. I have seen so many threads that pontificate on unprotected being totally safe because of safe chemistry. Well, I have to disagree. I am not saying that unprotected batteries are any more or less safe than protected batteries, I am simply saying that they are not absolutely safe as most seem to suggest. Take whatever recommendations and advice you want, just keep in the back of your head that nothing is absolutely safe.
If anybody wants to read a lot about the potential hazards of battery failure, check out this forum: Smoke and Fire, Hot Cells and Close Calls - The dangerous side of batteries
I will say, after reading those, I'll take my chances with safe chemistry batteries rather that the potential for uncontrolled burn, explosions, and lithium poisoning possible with Li Ion batteries if the protection circuit fails.
I'm not familiar with the Indulgence. Is it adequately vented?
As I understand it, IMR batteries will discharge gases if they fail, but no flame or explosion. Is it possible it was venting and pressure and heat built up inside the Indulgence?
No pun intended!
