Lowest resistance possible?

[Alchapwn]

How low is too low for the vamo to fire concerning resistance? I just built my very first coil on an RSST and because it got here b4 my vamo (and because im impatient) i dont know if it will fire a 1.3ohm coil...
Anyone know what is too low for a vamo? Thanks in advance for any help!

 

[Jaiofspam]

i believe it wont fire anything under 1.2ohms

Can anyone confirm?
Does 1.3ohms sound right for a 4/3 wrap of 30 AWG kanthal?

If you own a multimeter you can check the resistance across the coil.

I did check it with a multimeter. I checked it at the threading/pin on the bottom. I figured if the pin was going to add any resistance i would want an accurate measure of what would be hitting the vamo at that connection. Does that make any sense?
It grounded at 1.3 ohms after subtracting what resistance my multimeter leads are giving me. I hope the vamo will fire when it gets here.

From everything I've read here it should fire. I believe 1.2ohms is the bottom end where it will fire.

VAPE ON !!!!

VAPE ON !!!!

Confirmed. I checked with my good buddy phil busardo. watched the whole review over again to find the part where he confirms this. Pretty sure he is an accurate source. Now its just a waiting game till fasttech gets my package to me...

rolled a 1.2ohm coil on a smok octopus and it fired fine

Thanks! Exactly what I needed to hear. How did it vape? Been lookin at that one

is there an advantage to having such a low resistance coil?

 

[Alchapwn]

From what I understand, a more potent vape. More vapor and faster "warm up" of the coil. Someone correct me if I'm wrong

Ive been wondering this myself. Is there an advantage to a low resistance, and what is the trade off from using a lower resistance head (how much shorter is the battery life on a given charge)?

EDIT: I understand a more potent vape on a fixed voltage device, but I dont quite see it on a VV/VW like the VAMO. I noticed when switching to a lower resistance on my eGo batteries I got a stronger hit, but I am not seeing this on my V3

are you using variable watts or variable volts?
variable watts will up the voltage to compensate for the lower resistance if i'm not mistaken resulting in a stronger/warmer vape. I could, however, be wrong as i am still very new to this whole thing. just goin by what i research and how i understand it. no real-world info for me yet...

changing your wattage changes the voltage, as does changing the voltage, its just factoring in resistance and all for you, so you know the actual power you are going off of. IMO, there is no need for lower resistance heads in VV/VW, but if youre using a fixed voltage/wattage device, I can see the benefit. Unless you are talking about a dual coil carto, then I see the point. (a 1.5Ω DCT has 2x 3Ω coils wired in parallel to come out to a final impedance of 1.5Ω, so using the lower resistance allows you to send more power to each one since the PV has a max output)

Since this thread is on the VAMO board I assume you are using a VV/VW device, so i see no benefit in using a coil that low if that is the case.

it is on the vamo, and it is my first coil. The 1.3Ω coil is just what i built. I really just wanted to make sure it would fire at 1.3Ω instead of giving me an error. Thanks for your info tho! it really cleared it up for me. So assuming there are no advantages, are there any disadvantages to having a lower ohm coil? The only thing i guess there is to worry about would be the battery life.

Will a lower ohm coil have any significant impact on battery life?

Should i just try my hand at a 2Ω coil and call it good??

Your thoughts on making a micro coil? Have you heard of it? (basically wrapping many wraps, tightly, and pinched together so as they are touching to produce a lower ohm coil with more wraps.)

 

[Frankenmizer]

The lowest possible resistance is zero ohms..this causes the entire tank to flash-vape and also opens a portal to Dimension V...


Edit: The above is me joking, btw

this sounds amazing! lol

My thoughts and very minimal experience, using a lower resistance coil has made the battery life a bit shorter, but I cant say if its significant or not yet, I go between 1.8Ω and 2.5Ω depending on which tank I use, the 1.8 is from when I was on a FV (Fixed Voltage) device, waiting till it is dead before i swap it out. I see no problems with a 2Ω coil. I havent looked much into rebuilding, though I want to get into it as I am a big DIY guy. A micro coil just sounds like a speakers voice coil, just much fewer windings. But I know absolutely nothing about RBAs, been meaning to research, but I have been busy with work, speaking of which, i should go to bed, have to get up in 5 and a half hours for work and ive only been home for a few hours now.

My limited reading and experience leads me to the understanding that with some vv/vw devices, changing the resistance allows one to vape using one method at final power settings unreachable via the other. not sure if this is true, but it seems that I can get my iTaste VV v3 to vape cooler at 3.3 v with a 2.4 atty than 6 watt minimum. One setting scale is shifted relative to the other via coil resistance and it still fires...
