OH GOD! a hotrod blew up in eskys face!!!

yes you read right. a hotrod blew up in eskimos face while he was vaping... well to be honest it was apparently a battery which blew up, and shot apart the mod... so now we know to try to drill 32 degree slots in the tube for gaseous expansion... this is like the 4th time something like this happens... BUY PROTECTED BATTERIES!!! oh god.. he's got knicks on his hand from it lol

 

Yep, use protected batteries.

 

intresting when i warned him a few nights ago about unproteted batts.

 

bet that gave him lil scare...lol Glad hes ok though!

 

With an explosion like that, I think protected bats are more of a solution then a couple holes, But from now on I will have vent holes in my mods.

Glad your ok Eski!!

 

They are called protected batteries for a reason, now you know why. It sucks that it blew up, but live and learn. Always use protected batteries otherwise you are playing with a pipe bomb with no control over when it will go off.

 

Not sure holes in a mod would help in anyway, it wouldn't prevent a battery from exploding, it would just release any fumes out of the holes while it is exploding. and a battery exploding in there anyway will do more then just spew fumes out the holes. and see that hands n almost any mod cover most of the battery the vent would either be covered by the hand, or would spew the fumes out onto the hand. I don't think vents are the resolution, a Protected battery might be.

 

Holy Crap! That really sucks. I glad to hear he is ok though.

 

I bought some 14500 batteries on eBay from a place in China.Took a MONTH to arrive.They are TrustFire
900 mHa 3.6V....The ones I have been using are Trust Fire too,but they are blue colored. The ones I received from China are Grey????? I don`t see any writing on the grey ones that says "Protected"?????How do I know if they are are not????? Sure don`t want to have them blow up on me...ANy suggestions or answers greatly appreciated......Thanks!!!!!

 

That is exactly correct. CR2s go so quickly that the vent holes will not have time to do their job and the device will explode. That being said vent holes do help long term, but not against the device failing. Use some sort of protection circuit to prevent shorts on top of the switch inside protected batteries.

DealExtreme: $1.27 Charge/Discharge Protective Circuit Board for Rechargeable Li-Ion Batteries (17.4mm*1.9mm)

 

maybe a fuse is the answer? or circuit breaker lol

 

Wait, so this is the second time you've had CR2s blow up in your face?

Or are there two Eskimos that like using unprotected batteries and explosions?

There were two eskimo's i guess. My name on ECF is EskimoSwagg

 

Wow, glad he's ok. That thing looks shot.

 

Vent holes will more then help, they keep the rapidly expanding gases from being contained and thus exploding the device apart. I know, i've tested it. Doesn't mean you may not get burned, but it can help to keep shrapnel for flying into your face....

 

c'mon, man, that was funny...

 

I too had bought some different 18650's when I first got my SB (& don't use em anymore cuz I'm a 6V-head now & 3.7 just blows by comparison... until my JB arrives anyway). I have a variety f colors, some of them are blue, grey & maroon & all from the same manufacturer. Upon close inspection I found one set did not clearly mention 'protected' anywhere. The result is that the same manufacturers tend to make both protected & un-protected batts. Protected one's will say protected while the unprotected one's just wont say anything of the sort. It is therefore of utmost importance to buy batts that are 'protected' & not t just go by the color. So I realized after the fact that I now have 2 batts that are not protected & I'm afraid to bothr even opening them. BatteryJunction.com has a good variety & since they're in the US you wont have to wait too long for em. It should also be mentioned that LiFePO4 batteries are also considered to be safe due to safer chemistries that go into them making the risk for explosion nullified as well. In short: only buy batts that say "protected" or "LiFePO4" & you'll be safe.

 

Does it say "Rechargeable battery with PCB"?

 

Yeah that's a protected (PCB=Protection Circuit Board). Sorry I should have mentioned it's abbreviated name.
