Help with coils and inconsistent vape

[workingpapi]

Need some help. I am new to rebuilding coils but am doing good progress i believe. I would need to ask some help to find what am I doing wrong. When the tank is full of liquid I get very little vapor (no gurgling at all) it is usually when the tank is almost empty that i get awesome vapes (lots of vapor and dense) .... This is my config:

-Ego C twist battery (I believe is the 1600mA) usually set between 4 and 4.4 volts.
-Ribbon kanthal coil at 0.8 resistance
-cotton wick and flavor wick on top.
-Evod tank

The good thing is I dont get any gurgling or liquid in the driptip or battery is just I can't find a way to get dense vapes when the tank is full.. Only when it's almos empty. Thanks!!

The coil is ribbon kanthal 32 gauge and is of 4 coils above

Your ego twist battery only has between 2.0A-2.5A limit.

It is not safe to run a 0.8 coil build on it. Keep your builds above 1.5 ohms so that you do not exceed the amp rating of your battery.

welcome to ECF

sounds like you're doing everything right

JUST your resistance is about ½ too low ! (for ego)

double it (.08Ω to 1.6Ω) and you should be doing fine

Susan is correct

don't exceed the / a battery limitations (know the limit of what you're using)

Second the battery stuff.

As for the dense vapes, vacuum pressure generally helps keep that style of tank from flooding until they get fairly low, and then they're prone to flood. In your case, when they are starting to flood it's helping you, which makes me think you're using too much cotton. Try using less, and it should wick better while full (but may be more prone to flooding).

this is a good point
(I forgot to address)

keep reducing the size of your 'flavor wick' until
you are on the verge of flooding...

also, maybe it's vapor-locked
what I like to do is pinch off the air holes (3) in the tank base
and a couple qwik light sucks on the mouthpiece ;
see if bubbles rise inside the tank (problem fix'd)
too much will make it flood


keep us informed

Thank you everybody for your input, I will build a new coil later today I guess I am almost done with the juice in the tank so I am currently on the good vapes and don´t want to waste any of the valuable juice.

 

[workingpapi]

Thank you! Is there an analogy you could use so I know what is the right amount of cotton in the coil and what is the right amount of pressure, like I know if it´s too tight it doesn´t wick properly and if it´s to loose it will flood, but I see the videos and stuff but don´t seem to find the sweet spot between cotton amount and pressure when sliding it into the coil.

Thanks Susan, Can you shed some light on this matter, maybe refer me to a post where I will find the right and accurate explanation of this. In terms of ohms, amps, voltage and kanthal gauge all I have understood so far is the hose analogy, where a thicker hose will allow more water to pass through (something I read somewhere else), so basically my knowledge on this matter is this:

-Thicker (or flatter) kanthal has less resistance so current flows easier (heats up quicker)
-The more coils, the more resistance
-Lower Ohms is best (at least for dripper mods it is, I understand standard batteries don´t work the same way)
-Higher voltage = More vapor
-the higher mAh more battery duration

But I am still VERY VERY lost in terms of Amp limits, how voltage plays in the game and how to know the right voltage to use, how to determine the right resistance (in your builds) etc.. My Ego twist battery was a gift so I didn´t know until now, I googled images changing the mAh rates and I believe my Ego C Twist is a 1300mAh.

Thanks, to you and/or anybody who can help me with that.

So i just built a 9-coil coil (inception right there) so that would give me around 1.8ohms resistance, I have been doing some reading on electrics ... but yeah, for today I went with the resistance + 2 rule for voltage.. so I am running it at 3.6 to be on the safe side and half tank just to make sure it worked... I also loosen the cotton (less cotton and very littly twisted) and a little less flavor wick ... and so far SOOO good. Thank you all!! I took a little piece of everybody´s advise. I know this is definitely not the best build I will make but it´s way better than the last so far! Me Happy.

Congrats mate! What comes to mind is playing with your twisting, or lack of it. It's different with a tank than a dripper, as twisting can help make it less resistant to flooding, but in general twisting increases density, especially once it expands with the eliquid, so it won't flow as well. With a dripper, I just twist the end to pull it through. It's trickier with a tank though, as you don't want flooding, but it sounds like you're on the right track.
