Need help on Clapton Coil Build

[suspectK]

I input the values for one coil so why do I have to divide the resistance in half if it's only one coil so far? Because if there were two coils with the same resistance how would dividing .853 in half achieve .4265 (since each coil would have .853 ohms of resistance)?

Go to the Coil Build section of steam engine. Select dual coil, and input 0.4265 Ohms. After you do that, select single coil. You'll see that the wraps required will double.

It has double the surface area of wire(resistance*), so there is double the amount of electrons/current that can be pushed through the circuit by the charge/voltage.
*This may be what is confusing you, so go to the same coil building page. Input a lower number of wire gauge=larger wire, and you'll see that it decreases the resistance. This is essentially the same principal in using a multi-coil.*

I don't know why steam engine offers the option to figure out how to find the resistance of a clapton, and several other types of coils, but it doesn't offer that on the coil build section.

This kind of makes sense. I did learn about series/parallel circuits in Principles of Engineering. So in series if one coil fails so does the other since it has to pass through both coils to complete the circuit, but in parallel if one fails then the other coil takes a bigger load (resistance) to keep going? I hope I'm getting this right.

Yes, that is correct logic.

If I am doubling the battery capacity (current, if I am correct) then why won't it double the voltage as well? Here is a link the the batteries I bought: Samsung 25R 18650 2500mAh 20A Flat Top Battery
What does the mAh mean? On the website I saw a 3000mAh battery with 20A continuous, but mine is 25000mAh with 20A continuous. I don't get that since the continuous for both is still 20A.

Since you have two batteries in parallel, and we're talking about voltages, you just have each battery putting out its output. It doubles it's capacity, because it's essentially like just making a larger battery.

In series, you have the batteries stacked or directly connected to each other. So you have two sources of Energy/Voltage that is trying to go the same direction.

mAh- miliamp hour. So your batteries will push 2.5 Amps for one hour. The C-rating is different than the continuous rating.

By labeling them what do I write on the batteries? And by switching the contacts around I'm assuming putting the battery that was in the left side to the right and putting the battery from the right side to the left?

Whatever you want, honestly. I typically just use numbers or letters with mod batteries I marry together. So I have one set labeled "1, 2, 3" and the other set "11, 22, and 33."

If I lose two wraps I'll be left with 3 wraps. Isn't 3 wraps really bad for each coil because there will barely be any wraps? The guys on YouTube usually have like 6. However, I don't even know what resistance to use anymore since I am stuck on the whole voltage/amperage thing for ohm's law (listed above). Yeah I can charge the batteries with the mod. I just plug in the bottom micro USB port (it takes a while though). I honestly would rather just go back to variable wattage because I bought this mod just for the fact that it was regulated AND because of temp control (and other factors such as price,$38, and looks and features).

If you're using contact coils, compressed coils, then yeah, it will probably be too few wraps.

Try not to get caught up with Ohm's law. You have a regulated mod. This is something that is good to know, but it isn't a necessity with vaping. I'm sorry for not stressing that early on in this thread...conversation.

So basically you're like an electrical engineer? What was the studio for? Holy crap I am such a lost child I ask way too many questions. Vaping is SO much more complicated than I thought it would be

Yeah, that sounds good to me... I like to say I basically just push buttons.haha..but I'm currently not involved with anything like that.

Can you please provide screenshots? The number of wraps just go down when I switch from dual coil to single coil.

If in a parallel circuit only the amperage gets doubled, then how come when I vape it can go above 3.7 volts? Since the voltage doesn't double in a parallel circuit. The voltage can go above 3.7v on my mod.

What's the difference between contact coils and compressed coils?

I actually sold my regulated mod because I was having asthma while vaping. It was either me burning the dual clapton coils, or it could've been the juice. What happens when you glow the clapton coils too long when you just install em? On YouTube the guys glowed them little by little to introduce them to the mod and make sure there are no hotspots and it glowed orange. I've vaped on a titanium coil with that mod but it was ejuice from halocigs. This time I got juice from Mt. Baker Vapor and I sounded like someone who has bad asthma. And that's never happened to me before when I vaped with my friends on a mechanical mod.

Speaking of mechanical mod, how high can the watts go when you're vaping on it?

Correct. A dual coil's coil at 1 Ohm will have twice as many wraps as a 1 Ohm single coil.

Your mod is regulated. With a regulated mod that uses a boost circuit, like yours, there is a regulator that takes more current from the batteries, and it converts it into voltage that can be delivered to the atomizer.

What's the difference between contact coils and compressed coils?

Nothing at all..you may just see them described as either of those terms, or as macro, micro, and nano coils- This was when everyone first started compressing the coils together, and they would be macro, micro, and nano depending on the inner diameter of the coil(s).

Do you know what the PG and VG ratios of each juice was? It could very well be the flavoring involved, but it's likely that you may have some sort of trouble with one of those bases. It wouldn't have anything to do with the mod. I also wouldn't ever recommend Mt. Baker to anyone...even though there are thousands that enjoy them regularly. I am not one of them. I make my own liquid for a reason....I know what's in it.

Kanthal is a stable heating element. It is commonly found in many applications outside of vaping because of that. I'm sure that there wouldn't have caused an issue glowing your kanthal, clapton coils.

Did you use it in temperature control? I've found vaping to be much more enjoyable while using temperature "control." There is no way to get dry hits, and I can dial in certain juices more specifically to the temperature they're best at. I currently only use Stainless Steel 316L for my coils, and not all TC mods offer the use of SS wire.

I don't use titanium, due to the fact you supposedly can't glow the coils after changing wicks to clean them, and titanium creates titanium dioxide after being brought up to a certain temperature. Someone with experience that I trust is @Rossum. I haven't read his blog on titanium coils, but there may be helpful information there.

Speaking of mechanical mod, how high can the watts go when you're vaping on it?

There is no regulator with a mechanical mod, and there are no safety features, so the Wattage starts out at a certain level, and it will drop constantly until the battery is discharged. There's a lot more knowledge needed to be able to use a mechanical at high wattages safely.

There's also the factor of getting quality batteries. It is easy to get fake batteries, so always use a reliable vendor when purchasing them. I've been out of the cloud chasing game with mechanicals for a long time(especially in the vaping world), so the only battery I can recommend is the Sony VTC4. It was labeled as a 30 Amp continuous battery, but apparently that is not the case...even though it is labeled as a 30 Amp battery in moochs' picture in his blog, as well as the VTC3 but not the VTC5.

I do not recommend ever pushing a battery outside of it's continuous rating. However, the lower in resistance you go, the more the battery will sag, and it won't deliver as much voltage to the coil(s). Even though it is not putting the energy all the way to the atomizer, it is still having a traumatic effect o the battery.
