Hi, ill try to do my best to ask this.

Is there a youtube video that talks about all the ohms and volts and watts and what to look out for, or what you want to do to make sure you are building your coils in a safe manner?

I dont understand the use of a tester, If you are running a mech mod, and a really good battery, If you try and do any of the coils off youtube (IE. Rip Trippers videos of micro coils or crazy coil set ups) If the coil ends up running anywhere between .29 ohms and .9 ohms, does it really matter? I mean, if you were shooting to build a .27 ohm coil and it comes out to that, then you would use it, right? So even if it is over a little, like .29, then it would still be fine to use, no?

This is what confuses me, Either way, If I were to pop it on the meter, sure, I would know what ohms it is, But what are you looking for as far as what is NOT OK to use? How do you know how many wraps do what, What type of set up will effect different aspects of the vapor which ones will give more vapor or more dense vapor, etc etc.

Is there a video explaining all this in detail? Because I am seriously confused.

Right now, I am running a mech mod on a sony 2600mAh battery (I think the vts?) and it is a duel coil set up, with 3 wraps (not touching) on each side, when the person at the shop did it, the first time, it came out to .32 ohms. So what would happen if I duplicated the wrap, would I be safe to assume that doing 3 wraps on each side again will produce the same ohms and effects safely? And what would happen if I were to add an additional wrap on each side? Would I get more vapor production? (What would I need to do to get more vapor?)

Sorry if I am confusing, I am confused myself.

Any help would be great.

Thank you.


EDIT: JUST TO BE CLEAR - I am picking up a tester before I start any builds, The number i provided above are not what I want, or what I am shooting for (I don't know what to shoot for yet) They are just examples to convey my question about the small differences (in numbers) and how that affects things.

Go to this thread and read post #17 then click on his blogs and read them; lots of good information. As for running a 0.32 ohm coil on a battery that you don't even know what the amp rating on is dangerous IMO. It is irresponsible for anyone to send someone home with that kind of coil who doesn't have a good working knowledge of electricity and the consequences of misuse of it.

You can use this as a guide https://docs.google.com/spreadsheet...ZEtmY0pPYzBvdUw2blJHVjdkc1E&usp=sharing#gid=0

Yeah probably not the best thing to sell to someone, But I got it, So i need to learn. haha

Which thread is "this" thread?

You need a meter (ohms tester). Even when I just rewick without changing the coil, I pop it on the meter to verify that nothing's loosened up (higher than expected ohms) or shorted out ( 0 ohms) before putting the atty back in service. Besides, if you don't know the resistance you're getting, how do you know what effect the changes you make from one coil to another are making?

Yes, I use coils that come out a tenth different than what I was expecting, but if they are way off, I'll double check what I'm doing and probably start over.

You want a meter. Safety aside, the difference in how a .29 and .9 will vape (as per your examples) is MASSIVE.

You are just going to need to buy a bunch of wire and experiment to find what works best for you.

steam engine is also a good resource for coil building and can help you hit a target resistance

Thank you.

1: Use of a tester:
A meter, first of all is to test for a short.

2: A really good battery:
It's easier to decide that a battery is bad when it blows up that to decide that a battery was good because it didn't blow up yet.

3: 0.29 ohm and 0.9 ohms.
Using 4 volts: thats anywhere from 55 watts to 18 watts.
The particular ohms you want depends on the coil wire gauge that you are using; unless you have a kick, in which case you can adjust the kick to suit the coil.

4: 0.29 to 0.27:
yes that's just a 10% variation.


I think you should experiment with 30 gauge first.
And I think you should stay over 1 ohm until you no longer feel confused.

Thanks guys. I am picking up a tester first and foremost. The numbers I was giving were just to help frame my questions.

Thanks for the youtube videos. I am going to start watching.

So to see if I understand THIS POINT, after you built something, after you have tested it, and know its not shorted, and that the battery is GOOD, It IS POSSIBLE to run a mech mod, with any of the coil set ups seen by "trusted" sources, and be ABLE to go as low as a .29 (if that is what you prefer) and all the way up to 1.xx to suit your needs right? - I guess the question could be asked differently as, going lower than a .29, at what point do you create a pipe bomb essentially? .15? .11? .04? - Thats not the actual question, but that is sort of the framing behind my entire post.

The closer you get to zero, the closer you get to the edge of the cliff.

A good battery is the rope you're holding onto. Unfortunately you can't really check the battery yourself, you have to depend on the reputation of the supplier.


Are you using 26 gauge?

Before you try sub ohms you really need to read and understand about building coils and how to get what you want. I think everyone above have posted some really good threads so you should be good to go. oh and as far as trying to get a .27 and ending up with a .28 that little difference in my opinion isnt enough to worry about. difference between .27 and .9 is alot. Good luck.

Ahh see, thats what I am still getting hung up on, so if a little difference doesn't matter, then please try and clarify this for me. Ill try my best to ask it... If you are shooting to build a .31 coil. And once you are done building it, and you test it, It comes out to .45, Does it mean this coil is no good? Other than testing it for a short, do the ohms matter at that point? Or the reverse, If you are trying to build a coil and you think it is going to come out to something like .5 and when you test it, it ends up reading a .29, does it mean that it is no good also? I mean, if you were originally shooting to make a .29 coil, then it would be correct us that was what you expected, therefore ok to use, But if you think its suppose to be higher, Why does it MATTER if it is lower? (Aside from making sure the battery supports it)

Am I making sense at all? Basically, If you build a coil to whatever ohm, and it comes to something completely different than you thought, does it really matter? (Build wise, not compatibility with the battery-wise)

It can vary to what your shooting for and still be good, you might not like the results but as long as it's built correctly, the leads are snug and it's not shorting you may still want to use it.

If you were shooting for .31 which is 51.6 watts at 4 volts but wound up with a .45 build which is 35.5 watts at 4 volts it might be cooler than you were wanting. A lower ohm builds equals higher wattage (warmer) at the same voltage.

With the ohms your referring to you need to be safe, read up and make sure you've got the proper equipment, battery and everything is set up correctly. The lower ohms you go the more stress you're putting on the battery and equipment you're using.

If you spent time building coils you wouldn't be asking.

For example,
1;
do you have a meter that can distinguish between a 0.31 ohm and a 0.32 ohm?

2:
Why would you be 'shooting to build a 0.31 coil'.
Maybe you would be shooting for 0.3, or 0.4

I think the question you are trying to ask is why does the exact ohms matter;
If you can adjust the voltage then it does not matter.
If you are using a fixed voltage, then the only thing you can adjust is the ohms. ..... and/or the gauge of wire.

This is handy -but needs accuracy confirmed:
Coil reader.jpg

A good version of this is most important for safety and diagnosing problems:
Multimeter.jpg

Not realizing what will not work can end in tragic results
Understanding is the best safety tip I can give.

Now what you are attempting to do and verify you have done it correctly before attempting to use.

Yes, that is what I am asking. I have a mech mod, so I cant change the volts.

I was trying to think about it more this morning. I guess what I am really referring to is, If you build a coil at .03 and test it and it is fine (just using .03 as an example) Then technically, it should be fine to run 0.4, 0.5, 0.6 on the same battery right? So yes, that is what I mean by asking if it really matters what the ohms are, if your battery can handle the load of a lower ohm set up, then all the higher ohm coils should work too, in theory. Then you are just picking based off preference at that point right?

My dad owns and electrical company and knows ohms law inside and out, he has all the testers you could think of, So I am going to ask him to give me the rundown on ohms law and testing it to make sure I am not overloading the battery. That part is fine... I was just confused that if you have a battery, that is a good battery, and you CAN run it down to something really low, than in theory you could run any coil on it and it wouldn't matter. Right? That is my confusion...

That 2nd meter is exactly what my dad owns, I have used it before out on the job site, I dont have a grasp on the ohms law like he does, but he will teach mean in the next week or so... If you read my post above, it should help you understand where my confusion was coming from.

I think of it like an airsoft gun and using li-poly batteries and how they get really hot, the larger motor in the gun you use, the more it pulls on the battery, But if you have a big battery in the first place, that can handle the larger motors, You can effectively run all the smaller motors on it also with no issues.. I didn't know if was the same for coils, so if I have a higher ohm coil (0.6, 0.7) etc... would I need a different battery than the one I am already running at .33 (And it was tested by the shop)

0.03 are you crazy?


Yes higher ohms are fine, it's the lower ohms that is the problem.

You can add a kick to your mech to change volts instead of having to change coil.

I might add a kick and read about it.... So I talked to my dad and he expalined ohms amps and volts. And the math on it. I was confused that even if you have a higher ohm rating, it creates more resistance, which pulls more amps, and can overload the battery. So no, If you are running a .4 ohm coil, and you then build a .9 ohm coil, the risistance goes up, and it pulls more amps and can overheat the battery, so higer ohms on the same battery is NOT ok.

He said he would have to see my mod and see how it is set up, so he was just talking in general.

And to the guy above. I meant .3 Not .03 lol.

Again, Let me reiterate, these numbers are just examples to make a point, I am not shooting to build these specifically... I am just going to try and find one single coil that is going to give me a .... LOAD of vapor, and somewhat decent throat hit. I am just looking to make as big of a cloud as possible. Whatever ohms that comes out to, to be able to accomplish that to me is irrelevant. Whatever it comes to Ill make sure I have my set-up work for that.

So, I am gong to sit down, watch a youtube video of making a micro coil. I am going to build it, Then I am going to test it, Then I am going to take the ohms, and times it by 4 (the volts of my battery) and figure out the Amps, If the amps are under what my battery can handle. Then I should be fine. Yes? What am I missing?

Actually, Can anyone recommend a coil set up that give off a TON of vapor? Which coil set ups are the ones used for like cloud cashing competitions? - That's a whole other post, but maybe I can get a generalized answer on that.. What makes MORE vapor? Surface area? (physically bigger coils), Lower ohms?, etc etc...

Actually a .9 ohm coil puts less stress on the battery than the .4 ohm coil at the same voltage. A .4 ohm coil at 4 volts will pull 10 amps, a .09 ohm coil at 4 volts pulls 4.4 amps.

This ohms law calculator might help. Just input voltage and coil resistance(ohms), hit calculate and it will give you the rest.
