Coil Won't Glow Red

[davidos]

I was under the impression that Sony VTC4s are 30A, which is what I see them listed as. Is that wrong?

Davidos, which VTC battery and where did you get it? VTC5s will most likely be a fake, they haven't been made in a long time and it seems everyone has run out of old stock. The Sony VTCs get cloned, so it's best to get them from a recommended vendor like Illumn.com. For an Ohm meter I would recommend USA Ohm Meter. There are cheaper ones out there but these are the best IMO and are highly regarded.

Its a VTC4 I purchased from my local cape shop is a 30a

Unless you go real low with high gauge wire quad on a mech is very lacking. Do up some dual 28 or better 30g around .4-.5 and the nemi should rip

Amount of wire, gauge, resistance. All go hand in hand on a mech and a properly tuned and balanced build will be balls out

 

[davidos]

When you build a quad coil the resistance is divided by 4. If 1 coil measures out to 1 ohm, then a quad would measure out to .25 ohms.

So to figure out how many ohms my build can hold I would use a calculator( not a calculator but a resistance calculator)

So Do a 30g build? A 30g build 7 wrap quad coil or dual coil?

Well personally I don't do the micro coil thing so for my nucleus i go 5 wraps of 30 for around .5 .6.

in duals if your going 7:wraps i would try 28 i think.

Personally i try to keep the overall amount of wire to a reasonable minimum for fast reaction times

I thought both existed -- 30A versions with less mAh, 20A versions with more. But looking at it now I'm kind of blowing my own mind. I thought I had 20A VTC4's for the longest time, but I guess they're actually 30A? Hm. Still, I wouldn't push any battery past 20A. That's such an excessive amount of power. 10A is like, 100x more than enough to kill a man.

Also, quad coil? Why? You'd be better off with a large surface-area dual coil. Not to mention fitting a quad coil into a Patriot is gonna be a nightmare, lol.

Which would burn faster 30g 5wrap or a 28g 7 wrap

vtc4's are 30 amp batteries -- vtc5's are 20-25 iirc i think its 25 but one of those two -- but yeah their unicorns at this point -- anyplace you see selling them is probably slinging counterfeit goods

True

the thicker the wire the more time it takes to heat up... but the more surface area of wire on cotton the better... so its a balancing act... just experiment and find what you like better.

A lot of good info is in the steam engine site that people have posted.

Could you link me a URL? Possibly?

here you go
Coil wrapping | Steam Engine | free vaping calculators

On the page you can use the ohms law and battery drain tabs for more info.

Gonna assume it's a VTC4, 20A battery (probably a safe assumption).

At that resistance, the lowest you could theoretically build is .22 ohms. With a fully charged battery, this would put you RIGHT at your amperage limit. You don't want to be at the limit. It's a good idea to allow at least 30-50% headroom to allow variances in the battery/coil/other random factors that you can't exactly control. You can plug the numbers into Steam Engine to figure out what resistances produce what amperage. For example, you can plug in the voltage of your fully charged battery (4.2V) and the resistance of your coil. Steam-Engine will tell you what amperage that's producing, and what wattage that's producing. You can switch the variables around -- the calculator is very dynamic.

Your limit is 20A, but I would suggest keeping it lower than 13A -- that's a metric "****load" of power man.

nyiddle linked it already -- you can get it for your phone too...

I tried posting a pic of my build but the file was too large

 

[davidos]

Tue build I have now

 

[tehdarkaura]

got a bit of gunk on there -- pull that wick out and dry burn your coils and it will work a little better

thanks all the guy, learn a lot
