Minor Difference in ohms with same exact build?

[CTVayper222]

Okay so I run MXJO batteries exclusively and I love my builds around .2 area - .5
I started with a .5 for my first build and went to .4, then .3 and now I'm stuck on my 24 gauge kanthal, 6 wrap dual build which reads out to .21 to .23...

My question is why would the same build be .02 ohms off. Both builds are extremely clean micro coils wrapped around a 2mm screwdriver. They aren't janky whatsoever. I am kind of OCD about stuff so I always do really clean builds. I bought a derringer atty last week (which is my favorite so far, AMAZING!) and I did that same build which came out to .23

I just bought some new juice today (Doughnut Pounder from Grimm Green's line epiclouds - also amazing) and I did the same build on a Mutation X V1 and it's reading to .21 ohms.

Why does this happen and I already checked all my posts (yes I use a freaking ohm reader religiously lol), and I always build, check, wick, double check, and check and check all day long. I even tap my coils when on the reader to make sure nothing is shorting or loosely connected. Everything is tight and in perfect condition and I still have the difference in ohms: Derringer at .23 and Mutation X at .21

I'm not too worried and I KNOW... MXJO are 20a continuous and .21 ohms on a full charge is pushing 20 amps. (I know ohms law very well) and I know .23 pushes about 18 amps. I know nobody will advise this but I know soooo many people who even run .08's on a mech mod with MXJO (I am not that crazy) but my question is 1) why is this difference in ohms occurring, and 2) what's the lowest you guys have built on MXJO batteries or similar spec batteries and did it cause any issues other than possibly depleting the life expectancy of the battery itself?

Please play nice and give good feedback if possible.

Happy vaping everyone!

.02 ohms?? might have been the connection on the ohm meter to the + pin of the atty... any non continuous "connection" can suffer from odd ohm readings... its not like you are going to get a 100% connect with 2 semi flat surfaces meeting...

 

[CTVayper222]

Yeah but I have checked and checked and it just seems odd that the same build and same amount of cotton would produce a .23 on one atty and a .21 on another atty.... the pins do touch the readers contact because if not the ohms would be jumping especially when tapping the coils and leads

 

[Train2]

Leg length or quality of the contact - that's a VERY small variance in resistance. Heck, the WIRE might not be completely uniform...

 

[ElConquistador]

That's pretty normal for my builds. Build them exactly the same way and the resistance varies a little every time.

What is the error on the device you are using to measure the resistance? If it's 0.02 ohms or more, I'd say you're fine.

It's because that is a tiny margin of difference. Heck repositioning your coils can cause the ohms to change ever so slightly. Also the tightness of the coils come into play. Just because a cool visually looks exact to another does not mean it is. Wire stretches and shrinks and two coils can vary in ohms depending on how tightly they are wrapped.

.02 seems to damn well perfect
