If I'm thinking of the same story that you are that battery started to vent because it had ran below it's lowest rated discharge state, and went into a kind of 'self-destruction' cycle. The batteries shipped with the Protege have internal protections against this. That and the amount/ quality of the vapor extremely sucks way before the shipped batteries reach the cut-off state, so you will have taken it out and replaced with a fresh battery before anything bad happens.
Someone please correct me if I'm wrong, I don't want to put out misleading information.

You have to be pretty careless to have it happen. Usually vapor drops off to just about nada before ya can do something bad. Steve ran many tests and even tried to short the unit and blow the bats up, and he couldn't. So I wouldn't worry about it...Just be cautious and recharge often, dont run your bats forever...think about how long ya been vaping on the same battery. I also have a multimeter that I check my bats voltage and see where it is in the discharge cycle, witch helps. So I can pull my battery out, check its voltage and know how much time roughly I have before I should recharge.

Ya thats what I hear from a lot of people.
Im just more curious whats been done IF this possibly happened. Like worse case senario.

Overlord,
Yea, I hear ya. I have noticed, and I'm sure you have that the switch itself is loose and there is venting there. Also, I believe the way the switch is made, like I said before, that vapor drops off before you can fully discharge your bats. Like a 3.7volt battery...fully charged off the charger is 4.2 volts. Around 3.4ish your barely getting any vapor if any. So Its pretty hard to fully discharge the bat. you get no vapor before its fully discharged because of the power ya need to run switch/atty. So I wouldnt worry about it, just be cautious always.
You could invest in some ultrafire/trustfire protected batterys also, if its that much of a worry for ya. Maybe Steve will jump in here....im sure he can put your mind to rest =)

I am not ENTIRELY sure what will happen if a battery decided to not just vent but *blow up* per say in the Protege. I tried to make it happen by shorting the switch. I left the battery in for 15 minutes, to the point where it went from blistering hott, to luke warm. The battery vented through the switch.
The only vent on the Protege that would work would be on the end cap itself. Positioning them further up the tube, I don't feel would lend any help? Especially putting them towards the center of the battery. Being that the switch isn't entirely sealed, does allow the unit to vent through there.
I think the main concern is just user awareness. If you're batteries or tube is getting a bit warm, unscrew the end cap and drop the batteries out which will cease any and all issues. For those occasions where a battery has blown up, there has to be some sort of neglect ...
There are risks to using any type of device. Know and understand these risks before you use it, and have the knowledge to know what to do if such an instance happens

Thanks CaSH and thanks everyone for their advise 
I agree too that there are other variables that most likely caused explosions to happen

Yea...Like the most recent incident with the GG...and cr2 bats...he said he felt the tube get really warm but didnt think anything of it, and continued to vape........so like steve said just being aware that when you feel any kind of warm/hot..take a break...pop end cap...and make sure...
I think that even if you drilled a hole in the and cap, if the battery was going to explode (Not Vent but explode) no venting system would help.
Even if the bottom was off of the unit there would still be an explosion.
Lithium batteries explode violently, they burn @r 3000° and put out a toxic smoke.
One or two little holes wouldn't stop that. If anything it'd be a flame thrower in your hand for 3 or 4 seconds.

I had a 14500 go bad in one of my Protege's. It popped the little cap on top of the 14500 and just stopped working. I didn't even realize what had happened until I took the battery out because it was dead. I tried to charge it and the light wouldn't turn Red. When I looked at the batt I noticed a little brown mark/stain around the top cap.

i was gonna say - the endcap would probably blow out pretty easy - but there really isn't a real "seal" between the button housing and the tube of the protege...
Yes the Tenergy LifePo4 batteries that come with the v2 are protected batteries.

No they are not. LiFePO4's do not come protected because the chemistry is much safer than Li-ion chemistry. Below is some info on them.
Safety
LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese spinel. The Fe-P-O bond is stronger than the Co-O bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating (generally over 800 °C) does breakdown occur and this bond stability greatly reduces the risk of thermal runaway when compared with LiCoO2.
As lithium migrates out of the cathode in a LiCoO2 cell, the CoO2 undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO4 are structurally similar which means that LiFePO4 cells are more structurally stable than LiCoO2 cells.
No lithium remains in the cathode of a fully charged LiFePO4 cellin a LiCoO2 cell, approximately 50% remains in the cathode. LiFePO4 is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells.[4]
rfw2003... Thanks man. One more question, how about the batteries for the protege the 14500 batteries are they protected too?
rfw2003.... read Pete54 comment on the rcr123a batteries now am not sure who to believe 
This is from Tenergy's site concerning these batteries. They appear to have a 2.2v discharge cut-off and and overcharge cut-off but they don't mention protection from short circuit. I do not see a PCB on them. I choose these over protected Li-ion batts because I believe that they are much safer. Either way, protected or LiFePO4, you are much safer than unprotected. Could you have a problem using these? It's possible but not probable. Just pay attention to what you are doing and rotate matched pairs BEFORE they die on you. I get 4-5 hours on them so just change them out after a few hours.

O.k. I retract the Tenergy's being a protected battery, it was the AW brand that I read that have the protection circuit on them. But yes LifePo4 batteries are much much safer then standard Lithium Ion batteries, and will not explode or catch fire.
The 14500 batteries that come with the Protoge are not protected but there are protected 14500's availible at various stores. Steve did try by shorting the switch in a protoge to get one to explode but never could. So take what ever approach you want with the protoge.

hi guys
does anyone think itd be a good idea to make a sticky for the protege/other devices on ps forum for new owners on risks and in event of explosion advice???i know it might scare people off but if they want to safely use their devices it would be a good idea IMO to have it out there easy to see to prevent any issues?if there is one can i get a link to it?its all on this post but eventually this will get buried...
