0.12 ohm inquiry

[Br0k3nW1ngz]

ok so im well aware this is a low range but i need some info on a build i come across often. so i have a ss wire twisted build to be used on a pulse bf mod but i wanted to check my batteries can handle the build, im using sony vtc5a or a hb6 lg Pink one at 1500mah 30a , now when glowing coil on my aegis mod it would go 0.12 cold to 0.14-0.16 at red hot, since i know that ss will do this when heated am i ok using VTC5A

Hi and welcome,
IMO: No. that is too low (Ω) for any 18650 in the Pulse.
Stick to the regulated device if you "come across" (?) this build again. (I guess you are NOT making your own coils?)

Be safe
I

 

[Steve Parry]

No, it's not safe on a single battery mod. With the Pulse, it's pointless to go that low anyway because the voltage drop is so bad that you lose more from the inefficiency of the mod than you gain in resistance of the coil. You'll get a better vape on that box at .2 ohms than at .12.

i came across it often as i do make own coils but the style of twisted wire i have troyble tweaking the build to get a min 0.16, all my other builds go smoothly grom claptons to parallel staged heating seems its only my twisted wire attempts that turn out this way

0.22 is my max prefered i have 3 pulse bf mods and much prefer vaping on 0.16- 0.18 but ik 0.2 and up always reccm. i use ss as resistance goes up as heating so longer amps relax and reduce compared cool coil basline resistance so i get bit more wiggle room

 

[Br0k3nW1ngz]

guess i shpuld mentio did builds above 0.25 and on single battery a vtc5a same cell as in thread it uses too much power to ramp up and wastes capacity some

 

[Steve Parry]

It's your call. If you feel safe with it you can vape it, just be aware of your battery and check to see if it's heating up while you vape.

That's why I don't run twisted wires on mech mods. Ramp up time kills you so you have to build lower. I just use straight round wire so I don't have big ramp up times and I don't have to build so low.

yeah im noticing that about twisteds more now think ill put those builds back burner, ik my LGhb6 can handle it ig used sparingly as back up but it was my vtc5a im unsure on being strong enough

Play around with Coil wrapping | Steam Engine | free vaping calculators to get a handle on how different wires and coil styles work to produce a good vape. I don't think they support twisted wire coils, but you'll get some good info in the site that will educate you on how various coil sizes, wire types, and wrap counts work together.

The heat flux value on the right gives you an indication of how a particular coil with work at various wattages and temps.

i have vape tool pro app on cell and helps a good bit, still unsure of heat flux part as not used to seing the info so im not sure what to look for on that part

Scroll down to "Reading the Results" and "How the coil calculator works – what it does, and what it doesn't do" for an explanation of how to interpret what you are seeing as you change the parameters.

Heat Flux tells you how hot or cold the coil will be. Watch the little icon on the left turn from blue to green to yellow to red as you adjust the wattage.

Heat capacity tells you how fast or slow the coil will heat up. Change the target resistance and watch Heat capacity change from green to yellow to red.

At 0.2ohms or higher the vape on a Pulse is ridiculously weak.

Of course it is. The Pulse is a mech mod with a high voltage drop. The point is, you're not helping yourself on the pulse by building lower. Use your multimeter and test it, you'll see what I'm saying.

Put a .2 ohm build on it, fire it and measure the voltage. Put that in your ohms law formula and get your wattage that you're actually getting. Now, go down to .18 and hit the fire button and test the voltage. Enter that number into the equation and see what wattage you're getting. Mine was the same at .18 as at .2. When I dropped down to .15 ohms, my wattage went down, not up.

On a mod with high voltage drop, you reach a point where the amount of current you are losing into the mod is greater than the resistance drop of your coils can compensate for. On my Pulse mod, that resistance was .2 ohms. I agree that it was ridiculously weak, that's why I gave the mod away.

Works fine for me with single or parallel round wire builds.
Big mass claptons I use on a regulated mod.

im using sony vtc5a or a hb6 lg Pink one at 1500mah 30a , now when glowing coil on my aegis mod it would go 0.12 cold to 0.14-0.16 at red hot, since i know that ss will do this when heated am i ok using VTC5A

4.2v / .12Ω = 35A
HB6: 30A
VTC5A: 25A

The coils don't get red hot when you're vaping on them.

I can't confirm that. On my Pulse a .15 coil vapes a whole lot better than a .2 ohm coil. Sameish coilmass btw. Just switched from kanthal to n80.

I think it’s time for a few new batteries since the pulse accepts 20700’s, get yourself a vapcell gold 20700 (with the black writing) which are supposed to be rewraps of the Sanyo ncr20700a.

The resistance going higher when fired is normal...happens with a metals some more than others.. and no 18650 is safe at that ohm rate in a mech.... even in a regulated mod it's only safe IF the mod is working correctly.

thank you for clarifying info

I second the 20700 battery. I still wouldn't go that low on one of those. I had dual coils @.16 and they worked great. I got tired of the shortened battery life though so I put the single coil atty back on it. On the Pulse I have been really enjoying .2-.3 single coils.
