PLEASE take safety seriously

[keelalagirl55]

Guys...I cannot stress enough to please listen when Snow or Mordy talk about safety....overcharging batts, vent holes, ANYTHING. I have a link that was updated yesterday by Rolygate that is a must read!

PLEASE please take Snow seriously about these vent holes he mentioned in his review. There is no such thing as a 100% safe battery.

Thank you for posting this Ms. Keelalagirl. Again why using the dual coil tanks at 1.5ohms on the 5v OMG is at the users own risk....

 

[neonrust]

That is some scary stuff. Scary enough to make me do some more research.....scary research indeed(see quote below).

****UPDATE 2012-01-21 - The most serious mod battery explosion ever reported has taken place. It involved a pair of Tenergy Li-FePo4 cells in series. We have warned about these cells for at least a year.
DO NOT IGNORE ECF BATTERY WARNINGS*****

Those batts are in the OMG....but not mine....as of now it is disassembled until I feel 100% safe.

Thanks for the info......unfortunately sad info as I love the OMG.

Hi Fam,

FYI, we just got our single coil carts for ourt tanks, they will be available on Monday!!!

Always be careful with ALL electronic products whch use lithium batteries.

I am working on every single quality cotrol issue there is, and promise.....alll wll be the very BEST.

JFYI, the single coils ROCK my world, they will yours, as well.

Be ready for many more surprises in near future.

Vape-on

Steve

I have disassembled my OMG, and will not be using it again. After reading of the incident this morning, I had increased the size of the vent hole, but based on the reading and research, and the warning against Tenergy Li-FePo4 cells in series, I will not use this mod again. I like vaping, but I like my face and eyesight better.

This is a personal decision. I am far more comfortable erring on the far side of caution.

 

[Morandir835]

Neonrust sir understand your fears. Speaking as someone who vapes heavily and spent a good week torture testing the OMG, as long as you stick to cool and wow carts your risk of an issue is minimal. If you get the 7 flashes while vaping (not the usual flashes of dead batts), put it down for 10-15 minutes. The danger comes in with use of low ohm (under 2.0ohms) cartos/atty's. My biggest question is was this mod using a setp down feature or not. At full charge without a step down of any sort you're talking with those batts a load voltage in the range of 6.2-6.5v. A 1.5ohm carto at 6.3v will pull 4.2amps. 1.875 is the limit per each batt on the tenergy LiFePo 123's. You're pulling twice that using it in a stacked set up. Good for short bursts, but longer ones, well.... Had the person in question been running that, in a non vented mod, it was a sure fire recipe for the horrible event that took place. You're pulling 3.48a or so on a fully charged OMG with a 1.5ohm dual coil. Still very close to the max, but at least it's not past it. Still running that close to the maximum amperage is dangerous. So again, stick to wow (2.3ohm avg.) or cool carts (3.3ohm abg.), avoid deep cycling, check to make sure your batts are coming off the charger in a propper range (3.76v off load), and be watchful if the tube starts to get hot, and you should be as safe as possible. There is no safe batt, but with safe practices you can avoid a lot of the risks...

I take it these are the ones that are not safe?

Tenergy 2 RCR123A 3.0V 750mAh Rechargeable LiFePO4 Li-Ion Batteries Kit with AC/DC Smart Charger Tenergy 30203

 

[Joyce]

5vz, that would appear to be the ones. Interesting that the information given states that they will never explode.

 

[5vz]

Thank you Joyce.

 

[Morandir835]

5vz (sir or Ms.?) no battery is safe technically. Until all the details are known can't say what caused the issue yet. It's a shame it happened, atrocity that an non vented mod running stacked batts was ever sold, but that doesn't mean the batts are completely to blame. The safest batt on the market is the aw imr, even those go boom under the right conditions. Understand the fears, but any fat batt, mod, etc. is a potential explosion risk if proper safety isn't followed. The higher the mah, the more danger associated. If people do their homework before hand though, your risks are minimized....

 

[5vz]

Thank you Morandir. It does get confusing reading all of the battery information though. Some of us are a little slow on the uptake when it comes to things as such, the more numbers and ratings, the more confusing. I have no idea what a C rating is, read that in roly's posts, and no idea how to tell what battery has what.

I do understand we do not have any details on what has happened, and should not panic.

 

[Morandir835]

5vz c rating is the current draw on the batts. You take the mah and times it by c. In other words-

900mah with a 4c rating can pull 3.6a without failing. A 2500mah batt with a 1c rating can only pull 2.5a

+1 Morandir hon!!!

I honestly didn't wanna send out a scare signal, but more of a warning to pay attention. For all we know, the mod that exploded, the guy made himself. And I didn't necessarily want this to be related to the OMG and the batts that come with it....it is for ANY and EVERY batt and Mod out there. Be aware and be conscientious. I wanted to share this here with my V4L family because I know there are some that do use other equipment as well. It was in no way meant to be directed towards V4L or their products.....but for ALL products EVERYWHERE.

I have heard of other batts (non-mod) exploding as well from misuse. Overcharging is another big no no with a lot of these batts. There is an inherent risk that runs with ANY electronic device....I mean, I've seen where computers have melted.

It's just an awareness and a Pay Attention story. Treat all your hardware with care and respect. It's not just Tenergy, ANY batt can have issues. Check your mod batts often, if there is any deformity, or tear in the protective covering, toss them! Don't risk it. Don't leave batts on a charger unattended......and that is even good practice even if your charger has a shutoff feature.

 

[plantlvr]

Wow scary stuff! I have a habit of leaving the house to go to work with my batts charging, been doing that for 2+ years....Maybe not such a good idea hmmm??

 

[Morandir835]

Ms. Plantlvr depends on the batt and charger. Worst I've seen from a kr808 failing from an overcharge is smoke come out the vent holes on the cap. That doesn't mean it's 100% safe, but smaller batts don't explode the same way say an ego or a mod batt will. Your best move is to use the best charger available for said batt. Why always speak highly of the slim line, tried to overt charge batts on it with out success. When charging 18650's use a pila charger. Intentionally left batts charging for a day on them (in fire proof bag for lithium ion batts) to see what would happen and the batts didn't explode or overcharge. Just know the risks and do your best to avoid them....

 

[keelalagirl55]

I almost hit the like button Morandir.....but I'll like you and your post via a post

You say it all so much better!!! Thank you (((hugs)))

 

[EleanorR]

Morandir, you are simply . . . irreplaceable.

Thanks so much for ALL you do.

 

[Morandir835]

Just doing my part Ms. Keelalagirl and Lady Eleanor.

This is a very disconcerting story and one of my largest worries when it comes to any Mod. Even your KR batteries have vent holes located around the ash caps with sealed manuals. There is no such thing as a safe battery and oddly enough I noted several concerns about it on the original version of my 5V OMG review.

I made the conscious decision to edit this out of the original version by emphasizing use with high resistance cartos and enlarging the vent hole for safety. I have provided an original version of the review on my profile for those that would care to view it.

For those that have purchased the 5V OMG, please find a way to drill out and enlarge the vent hole on the battery cap...just to ensure safety. As well, after using the 1.5 Ohm Dual Coil Cartomizers, replace it with a 2.0 Ohm or 2.5 Ohm Dual Coil Cartomizer.

If the Mod noted in the story had a vent hole, a properly sized vent hole the tube would not have pressurized and exploded. A vent hole should be at least 1.5-2mm in diameter to allow adequate rapid out-gassing should a battery overheat.

Here is a pic of my 5v OMG with an enlarged vent hole.

In many cases Mod manufacturers do not recommend stacking batteries without voiding the warranty. Other Mods require the use of protected batteries which have a protection chip inside of them that will not power 1.5ohm atomizer at anything above 4.2v. A ProVari and other high end mods will detect a 1.5 ohm atomizer and not allow the unit itself to fire above 4.2v on top of using protected batteries.

At 4.2v using 1.5 Ohm atomizer the total wattage is 11.76w.

The 5v OMG does not have any built in battery protection, nor do the batteries used with it. It will fire at 5.3v with 1.5 ohm atomizer this comes out to a whopping 18.72w drawing 3.53 amps on a 4 amp rated battery.

Now, you might say, "Ya but it says it's 3.0 .2 +/-...that is the resistance affecting the vapor, not what the battery sees, it sees a 1.5 ohm atomizer. This is also why your KR batteries drain out so quickly when you use a DVCT 1.5 ohm tank which works fine with 3.7v battery.

The 5v OMG can be a safer device if used with 2.0 Dual Coil or 2.5 Dual Coil which drops the amps down to a more acceptable power draw level. Add to that a properly sized vent hole and this unit should never go "boom". The batteries could still have an issue, but any battery could. However, when used at the proper power level and vented properly they won't explode.

Next time you run into a vaping Techno-Geek or a forum member that rushes out to test the newest device, then shares that information including safety issues...heed their warnings. There is a reason testing is important and a reason why numbers really do matter. Those like myself that share that information are only looking out of your safety and best interests.

Anybody can be a cheerleader or profess to knowing all about vaping, but the fact is...just because you have a couple of computers it does not make you a computer expert. This is why we are so extremely lucky to have Morandir as a member of the family for all his extensive testing.

 

[Kanza]

Well, I certainly feel safer DH and I exclusively use rechargeable batts for anything running on batteries and have <sigh> left them on charge FAR longer than we should <double sigh> Since most of them go into dive equipment, this isn't such a good idea...I will be more cautious and watch those little "charged" lights more carefully in the future

Thanks, Keelala, for bringing this to our attention and thanks, Morandir, for putting the science to work Ooops, SD posted right before I did so I have to include him and say, thanks for your helpful videos that answered all of my questions before I realized I had them Also, SD, you should take a bow yourself I consider myself lucky that BOTH of you are here to help us along the way to happy and SAFE vaping
