Coil questions.

[batman624]

I dont think Asbestos was concerned with the topic dying, but with you dying, instead.

With no offense intended, you claim to understand a complex electrical relationship, but have confusion over a pretty simple mathematical concept. Adding to that, your initial posts do kind of lead the reader to believe that "your friend" might actually be you.

Nobody is out here to get you. People just dont want to see your blown up hand all over the news and legislation that bans our tasty clouds.

This won't die unless the thread is closed. I say let nature take it's course

Keep in mind 30a is continuous discharge. Pulse discharge is much higher.
Not that I advocate going beyond the continuous rate.

Burst discharge as in "can do the continuous rating continuously and won't instantly self-destruct if occasionally exceeded." Not as in "perfectly fine to use each and every time the button is pressed."

One issue with batteries is that they deteriorate over time. More so if put under stress. A 30A battery running at 30+++ amps all the time will not remain a 30A battery very long.

All in all it was a really simple question that needed a simple answer. Didn't have to get so out of hand; my math was terrible, and my understanding even worse. Does not mean I don't know how to build, practice safety, or enjoy. I am progressing further into sub ohm territory out of my comfort zone (0.5-0.8) experimenting with tons of different builds wires and all the RDA's I could want. I guess I made myself look a bit foolish but it was a matter of confusing pertaining to a build, not vaping or subohm as a whole.

Thanks to the people who provided clarification and weren't elitist jerks, the majority of you can learn from these type of people - keep this community free of judgment- or else we will loose it! That's all, let the topic die.

Yes, it does mean you don't really know how to build or practice safety. If you don't know the difference between .08 and .8, you are sorely lacking in information. You are merely building by "rote," without a working knowledge.

WTH are they teaching people in school? This is a basic 7th grade fact. HOW IN THE HELL do you think you know enough to review builds if you don't know basic math? If it sounds harsh, it is because of your "pooh-pooh" attitude towards people who are trying to HELP you to not get your face blown off.

But if youd read what I said you'd realize I didnt understand the difference in the decimal point and relation to the battery. This is largely due to me building within the acceptable range and as a user pointed out I usually use an mvp to build on. The understanding of the decimal point was the issue and I understood I looked like an ... and I welcomed that. But some attacked me from every angle on the subject...I misunderstood one part of a picture I have a decent grasp on. Lets let this die were all on the Same [emoji106] page now !

And if you read what he is saying, he is saying BECAUSE you don't understand the basic principal of the difference in the decimal point, makes you an unknowledgeable vaper.

Learning the place of the decimal point is basic 4th grade math. Tenths place, hundreths place, etc...

.8 is like One tenth of (more so 8 tenths of)
.08 is like One Hundredth of (more so 8 hundredths of)

One hundredth of is a lot smaller than a tenth of something.

Knowing that basic little decimal point difference is HUGE! It means the difference between blowing your face off, or staying safe.

1 <-ten-thousands
0 <-thousands
0 <-hundreds
0 <-tens
.
2 <- tenths
0 <- hundredths
0 <- thousandths
0 <- ten-thousandths


Top to bottom as in left to right, so it would look like 1000.2000 (I put a 1 and 2 to make it more obvious what side of the decimal point I was talking about)

Please memorize this. Please.

I'm not a pro-vaper by any means, actually far from it, but I knew this information BEFORE I started vaping, so knowing the difference between .8 and .08, to me, is just common sense.

Please learn, and please stay safe. Not only for yourself, but for everyone else and the sake of vaping.

<snip>By the way, where can I find one of these 3/34 drill bits? I've looked everywhere.....

Yeah... good luck with that

 

[CloudsinCrowds]

Oh man so sad to see people lacking a functioning knowledge of ohms law and how it relates to our safety...
It really is getting out of line, seeing all these people who clearly are putting themselves in danger by simply not understanding these concepts fully. Its a shame that humans just think they can buy something and use it to its fullest potential without the proper knowledge..
I almost fell on the floor laughing reading this thread. .8 and .08 hahahahaha such a massive difference!

The largest continuous current on a 26650 is 20A. If it was your battery that was used, I would discharge and recycle it. Unless you are going to mark it and keep it for low current use (<10A). It has been stressed too much to safely push it to its limit again.

 

[Baditude]

Sorry I reached this thread late.

I agree with those before me who were critical of the OP not knowing basic fourth grade math skills. If you don't understand the basic principal of the difference in the decimal point in tenths & hundreths, it makes you an unknowledgeable and dangerous vaper. If you don't understand Ohm's Law as it relates to vaping and battery limits, or at least can't do simple computations with an Ohm's Law calculator, you have no business vaping at sub-ohms -- period.

You said you came here to learn something. Use the Ohm's Law Calculator to determine if the coil resistance of your RBA will pull more amps than the battery has to provide. Going over the amp limit of the battery can have catastrophic results. Note how the amp requirements of coils increase the lower in ohm you go.

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohm = dead shorted battery (see pics below)

There is no 18650 battery on the market which has more than a 30 amp continuous discharge rate. Any coil less than 0.1 ohm is too close to being a dead short. A battery which goes into thermal runaway from a dead short will vent extremely hot gases and possibly explode, no matter how many amps it has. Believe me, you don't want this happening inside a metal tube when your holding it in your hand and up to your face. Your so-called buddy has been extremely lucky up to this point. Any build less than 0.2 ohm is a death wish waiting to happen or complete ignorance to one's own safety.

Thank you so much baditude!
I am way too busy for a long winded post such as yours.
You're the man. It needed to be said.

Lithium battery shorted out.

Sorry, my mistake. He verified it was 0.0. I'm not sure. I know my laws and what not, and have been doing it for some time however I wasn't sure if 0.3 an .3 differed. According to him, it did. He was using a VTC5. he ran 22g royal wire, five wraps, 3/34 drill it I believe.

??? DEAD SHORT a connection with zero/near-zero resistance.It may be applied deliberately in order to perform tests, or, more usually, as the result of a catastrophic failure in some part/component.

Op or ops friend was building on an MVP, and the build was less then .1 which is as far down as the MVP can measure. ie .08

Not with 5 wraps of 22g roual wire on a 3/32 x 2 coils.
That's gonna be closer to .03 ohms.

I've seen builds like that.
I don't see the advantages of going that low.

These builds are showing up all over youtube....09 - .08 - .06 There claim is that the Sony VCT5 has a pulse rate of 80amps. They were talking yesterday at the local B&M about Rip Trippers even having a video now running a .06 or .08 build.

In all the videos they're saying "please make sure you use the right battery" (then show you a Sony 30amp) then tell you how they know what they're doing.

I'll be truthful, I'm glad this stuff wasn't around when I was 15-20 I TOTALLY would have been "that dude" (I still can't believe how I made it to 40) that took the videos as -the pros say it's okay as long as I have that GREEN battery..

How many people who don't know their batteries are just buying any green battery? Panasonic sells green batteries which are only 10 amps and looks very much like the 30 amp Sony batteries.

Too bad what I'm thinking about you, would get me banned more than likely. I asked a simple question, which needed a simple answer - no need to be a ..... I know very much what I'm doing with MY equipment, MY batteries, MY builds and MY MULTIMETER. when I was explained the 0.08 build, and shown it, that's what led to the confusion.... And the clarification I sought on that particular matter is just what I needed . I have never ventured under 0.4 ohms until just the day this topic was created BECAUSE I was told about something like this.

Are you sure? Maybe it was 0.04 ohms...

 

[Asbestos4004]

The battery that came with the remote for my crappy DVD player was green. Does that mean I'm ok at .3 ohms? Or maybe .03???? Not that there's a difference....
