not that bad, i know someone that vapes at .1 or was it 0.01 ohms, expecting it to blow up and it did, scary stuff

that is just ridiculous! I've got a friend that vapes at .09 and that scares me. .01 is more than asking for trouble. That is essentially a dead short right there..... But I have to ask, what are the details on his/her 'blow up'?

I don't mind that inevitable backlash, to each their own. To be honest, the battery was still holding a full charge and did not "need" to be replaced, so just out of sheer laziness and frugality. I've researched battery failures enough to feel comfortable with the blown out of proportion risks associated with them.
Heck, I sub ohm without and ohm meter too, OMG!:blush:

So you have no way to test if your charger was actually at fault for the problem... :facepalm: For that matter, how did you define "the battery was still holding a full charge" without a meter?

Like the title says, this morning I vented one of my vtc4's.... It has seen more than its fair share of use and the protective wrap was mostly gone on the positive side of the battery. I was on the way out the door with it in the charger to bring to work when I smelled something akin to a chemical fire. Looked down and the battery was hissing and smoking in the charger cradle, so I quickly yanked it out and threw it out into the yard. It hissed for just a moment and then fizzled out.
I presume that it had moved on the charger to the point that it was shorting out on itself. Moral of the story, replace your batteries, or at least replace the protective wraps at the first sign of wear. It could have been worse.

Could you describe the hissing and smoking as well as the fizzling?

I'll just leave this here:

Battery Shrink Wrap

I bought four rolls of this stuff and use it as soon as I see any issues with the battery wrapper. It's thin enough and so far there's been no clearance issues in any mods. Usually if the original wrapper is messed up enough I just cut it off, re-label the battery with my handy-dandy Dymo, and put this stuff on. And it sets with a hair dryer, but a heat gun is faster (if you happen to have one).

Thanks for answering, I was just curious. I've done way more than my fair share of things I knew were risky though batteries are just one thing I haven't (knowingly) taken a chance with. They kinda scare me. Might have something to do with sticking a bobby-pin in a wall socket when I was little.

I did the bobby pin, too :laugh: I was afraid to plug anything into a socket until I was about 11! I remember my first grade teacher asking me to plug in a projector, and knowing this teacher didn't like me, I thought she was trying to kill me. I screamed, "No!" and ran away.

If the wrapping on your batteries is getting shredded (as it has with mine), get yourself some PVC wrap and re-wrap them.

Without the wrap, the positive top and the negative outside are barely a mm apart...just asking to be shorted.

Just go on ebay and search for "18650 pvc wrap" and you'll find 2M (6 foot) rolls for a few bucks...

Thanks! I just bought some. I have a vtc4 that got a little tear. Its been in a plastic case waiting to be repaired.

This is just stupid. How long did you vape before you started to build, how much did you read. I dont care what you say, you need an ohm reading meter at minium if your building anything especially a sub ohm build. Disgraceful. This is to the op. And after going back and reading this thread I really dont think you take battery safety seriously. Damn man buy some wrap.

You dont need an ohm meter. Thats kinda ridiculous.


I mean, how can you be sure the ohm meter is accurate?

I have an ohm meter, and a multi meter, and I do use my ohm meter on every build, just because of sheer curiosity and habit.. but unless your stupid and have the kanthal touching, just being careful, u dont really need one.
P.S... i never build above 0.4 ohm... usually in the realm of 0.2
And if something messed up my coils or something, damn right i would rip out and rebuild, even if i didnt have a precious ohm meter. point being, if your using same gauge , same build, everyday, the only thing you need to ensure is you dont have a short, which is usually easy enough to eyeball if your not completely stupid


Plus most regulated devices have an ohms meter nowadays anyways.

Theres a lot of hype here...ventings happen in the best of cases. Oh well, you shorted a battery:vapor::vapor:

Just my opinion, but I don't think you're taking this seriously enough.

I agree with OP. It is not something that happens often. If 1% of the 18mm cells that are on the market failed by venting or by catastrophic failure we would hear it every day without fail. And very rarely do any cells have a catastrophic failure resulting in bodily harm or destruction of personal property.

I have to go with facts not the hype. It is not what it has been put out to be. I get tired of hearing how my mod is going to blow up and rip my head off.

Not gonna happen :2c:

I like brass and copper atty's too.

I agree, ohm meters are precious. Without using an ohm meter, how would you know if you had a cap touching a coil, if a 510 connection insulator was broken and causing a short, or if you had a piece of coil leg not cut off that was shorting a coil. Not completely stupid? So you're perfect and have never made a mistake or had something go wrong for you. Gotcha :rolleyes:

And not everyone uses the same build every day, specially when they are first starting out.

Yes, ventings can happen in the best of cases, but they are much less likely than in the worst of cases. Use a DMM regularly, take good care of your hardware, research and know what you're doing and IMO you will eliminate 99+% of the safety issues.

I was on board with your initial post as it seemed a cautionary tale and a good reminder to others. The flippant attitude about it since then...

1. Glad you're OK :)

2. What TheJakeBailey said, as he's less wordy than I.

I'd written a paragraph given you mad props for being willing to post that instead of burying it in your shame box, then read down a bit and went "Oh." Still mad props for that initial post, but it concerns me that you seem oblivious to the fact that if that situation had gone a little differently, you'd be posting asking how you prove to an inspector that a fire that burnt down an apartment complex wasn't intentional.

Hmm how do I know if a cap is touching... I look. Carefully. how about a leg, well, I fire a few times.

And while building, I have shorted coils...Once built on my mod.... and forgot to lock it.

Anyways... I use my ohm meter.

But I dont think that having an ohm meter is the most important thing in the world. Good to have one... but if you dont, its not the end of the world.

To be honest, there is a lot of fear mongering on this site, and its a little depressing.

Alot of people get up on their high horse , and act like mods be exploding left right and center. Sure it happens. just dont be stupid.

Plus technically, i dont use the ohm meter all the time. I build, Fire, clamp coils and then refire and then, wick and then test. so ive already fired a few times. But when I was waiting for slowtech to send my ohm meter, and my MVP ohm meter wasnt working. I didnt test. Still built. Didnt blow up.

Its not life diving without gear. its more like.. ... flying. Sure... you could die.... but you have a higher chance of being hit by a car.

Spencer, it seems you've become quite the expert in the last few months. It seems like only yesterday we had to read countless threads by you wondering what to upgrade your ego battery with. Now you're an expert builder who never goes above .2? So good you don't even need a meter. Hats off to you. Here's the thing, there would be a lot more venting threads if we didn't preach safe building practices. There would be many more incidents if we didn't stress the importance of using good batteries or ohm meters. Not everyone is as gifted as you to be able to see through a steel topcap to identify a stray leg. Congrats on your rapid progression to the top of the heap though.

    I'll jump your case for a different reason. Did you know that you can put a new wrapper on a battery when that is all that is wrong with it? Why didn't you do that?!?
