Newbie MOD learning, what to expect?

[superstarsticky]

Really liking the positive attitude!

If, I knew how to 'thumbs up' this I would! LOL

 

[superstarsticky]

Ohms law easy. Divide your voltage (4.2) by ohms (lets say .5) to get amps which would be just over 8. Also if making dual coils the amps double.

Ok, great! Couple questions. How do I figure my volts? So once I figure amps for the dual coil I just double it? 8+8=16

Now figuring all these things out, what numbers do I need to be aware of to know that I'm being 'safe'?

Max charge on the battery will be 4.2v. You want to play it safe and assume this value, even though it will drop.

Divide 4.2 by the resistance of the coils. OVERALL RESISTANCE, not per coil. Overall will be half of each individual coil.

You DEFINITELY want to get an Ohm Meter asap.

No, you add the ohm together of the coils before you divide.

 

[superstarsticky]

Well, the most important difference between clones and originals affecting huge clouds would be voltage drop. But I've read many posts where people claim their mod has a huge voltage drop, but they didn't check the voltage drop of the battery beforehand, and their mod had a very minor voltage drop.

I see, so just beware there are a lot of variable's here that all affect the end result. You definitely can't have tunnel vision with this hobby lol


Thanks man!

So you just lost me... Can you put together sort of a equation for me to follow?

Negative. Thats if it were in series. Dual coil is parallel which halves overall resistance, which doubles amps.

Yeah, Ohm's Law. jk

For example, dual coils at 1 ohm each will have an overall resistance of .5 ohms. Take 4.2 and divide it by .5, you get 8.4A. This is well below your 30A battery, so you are safe.

 

[StarsAndBars]

Think about it this way. You would be doubling the size of the conductor (coil ) which halves resistance. In parallel each coil gets 3.7 volts so it doubles the amp draw

 

[itskohler]

Wait wait wait, my thought process was right. My verbiage was way off.

 

[dripdaze]

No, you add the ohm together of the coils before you divide.

Two coils in parallel result in a total resistance that is half of the individual coils. I.E. Two 8 ohm coils in parallel equals 4 ohms.

 

[StarsAndBars]

Yeah, Ohm's Law. jk

For example, dual coils at 1 ohm each will have an overall resistance of .5 ohms. Take 4.2 and divide it by .5, you get 8.4A. This is well below your 30A battery, so you are safe.

Very much this

Why wouldn't a 1 ohm each dual coil mean a total value of 2 ohms? Which would mean an overall resistance of 1 ohm rather then .5 ohms?

 

[Tugg n chase]

You're definitely on the right track brother, and like Itskohler said, great attitude. Keep up the questions and do some more research. Youtube can be an asset for most of this too, just be aware the idea of "extreme" vaping has led to quite a few people posting vids of some unsafe set ups. Use your best judgement and it will all come together

Youre gonna confuse this guy. What you said would be true for a series but dual coil is parallel.

THIS is what I was thinking, and meant to say.

It would if they were in series, connected the way batteries are in a flashlight, stacked. They are not, they are in parallel. So resistance is halved.

 

[superstarsticky]

Ok, LOL and this is perfect. Makes sense to me. I was like why does the 8.4amps apply? Then I realize how it correlates with the battery amp draw.

This is becoming more and more simple.

Thanks all you all!

Oh, that's awesome!

Thanks for that simple explanation!
