New Member Asking for Help

[tsheafer]

Hello, all! New to the forum, and new to RDAs.
I joined the forum to get some insight and assistance in my current build and my future builds.


I'm currently running the Maraxus Clone with the authentic Patriot rda. 3.7V 18650 2500mAh battery.


I'm having trouble getting the right ohm reading. I tried two different micro-coil builds. Same build, just different size wraps.
The second time, I got the better result. But still not anywhere close to where I need to be.


I'm using 28g kanthal with 5 wraps around a 1/8in screwdriver to make the two micro coils. They look great and glow even better.
However, my ohm reader still reads at 0.7 ohms. It's my understanding that I want to me around the 0.2-0.3 range.
I can barely take one drag and it burns and is very harsh. Also, I'm producing very little vape.
I'm using 100% vg, 0mg juice.

I'm wanting to eventually get into cloud chasing, but I can't even begin to think about that when I can't even get a standard micro-coil build down. Needless to say, vape production is my main goal.


What am I doing wrong?
PLEASE HELP.

What am I doing wrong?

Sounds like you're trying to run before trying to walk.

There's no reason to build 2 coils first. You can just build 1 coil. Once you have 1 coil right, you can add a second similar coil.

Do you have a regulated mod?
A regulated mod is a good place to work at coil building the first time.

Do you have a good battery like a 30 amp battery?

Hello and welcome to the forum. Glad to have you here!

^^ What he said! My ouija board telling me you have a 20A continuous battery. Purple Efest?

 

[nyiddle]

Are you lining the airholes up with the coils? I've seen a surprising amount of people not doing this recently.

Welcome!! There is a lot here for the researching. Their is a search tool at the top for the ENTIRE forum. Also, there are many YouTube videos.

Glad you are here. It is a great hobby. Like the others said, one step at a time.

When I first started, people said to "get this" or "get that" $150 model. No, I am glad that i started at the bottom and learned as I went along. Reading, asking questions and personally experimenting really helped me. Going for the best right out of the gate wouldn't work for me.

Go for the single coil, learn and just enjoy a good vape.

A .2 or .3 rig with the same wicking will burn the hell out of you if this is the result you are getting with a .7 rig

You need to improve your wicking for starters..also as was suggested..try building single coils before duals.

Focus on getting solid results at 1 ohm before you try building sub ohm

Trust me..a proper one ohm build with 100% VG will give you a ton of vapor.

It's like the old saw that asks "How do you eat an elephant?"...the answer of course is one bite at a time...you can't eat the whole thing at one shot. Same with building coils.

Thanks so much for the replies! I'm going to respond to each one individually so I can keep my thoughts straight, as well as hit that 5 posts for a new member rule.

As far as starting with just a single coil, I just leave the third post alone? And I assume I'd only place cotton under the single coil, and not throught the entire bowl, correct? The only reason I went with the dual coil was because I've been watching a crap ton of videos on youtube and lots of them suggested for a newbie like me to start with a "standard" dual coil with 5 wraps using 26g or 28g kanthal.

Thought it seems all of you are telling me to try with the single first, then work up to the dual. I shall take your advice. =)

As far as the battery.....it's 2500mAh, 3.7V. How many amps is that? ha Not sure. Like I said....I'm super new to this.

Read my reply to edyle. The batteries I'm using (that are inside the MOD) are blue...if that tells you anything. ha

To get a solid 1 ohm build, do I need to just make a single coil? And should I increase the wraps around the screwdriver?
I guess my biggest stuggle is not knowing how to increase or decrease my ohms.

Will a lower ohm reading give me a harsher, harder vape? Or does the lower ohm reading give me a smoother, cooler vape?

Not good.

If you don't know the amps of your battery you should not be building. Are your batteries IMR (Li-Mn) or IMR/Hybrid, safe-chemistry, high drain batteries. These are the ONLY batteries safe for vaping.

Can you post a picture of them? Is there any writing on the battery?

I got the batteries from a local vapor store here in town. They're the only ones that they carry.

On the battery is printed: INR18650-25R Samsung SDI 2 2E82

Do you have a regulated mod?

If you have a regulated mod, you can start with your 1 single coil, and adjust the voltage to suit.
If you start out with a mechanical mod to begin with, you need to know what coil to build for it.

With 28 gauge kanthal, it's around a 1 ohm single coil that should work for the 4 volts you get on a mechanical mod.

If you do not know the details of your battery, you should not be thinking about 0.2 ohm dual coils; that's heading for trouble.
Thermal runaway on a lithium battery is not fun.

It's a mechanical mod. Not regulated. So, I need to do some research for what coils to use on my specific mod.

The only reason I was thinking about 0.2 ohms was based on what I was seeing on youtube. I just assumed that's what I needed to have.

I guess its these?


Samsung INR18650-25R 2500mAh - Kidney Puncher

should be decent I guess. 25 amps continuous seems decent enough just don't go too low. for the rest I don't know how safe this battery is. I know the VTC line doesn't explode and just vents but I don't know how this thing will react when something goes wrong.


Honestly you need to stop watching so many youtube videos. you shouldn't do what they do because vaping is different for everybody.

they might like the scorching hot vape or their dual coils.

some people prefer single coils at 1 ohm. for example rip trippers. rebuilds all the time and his favorite ohm setup is a single coil at 1 ohmish. not 0.2 ohm oh my god POWEEER.

Honestly I think people should start with regulated devices. mechanical mods are for the advanced people who knows what they are doing. I mean you didn't know your amps so you shouldn't playing with something like this. one single mess up and you got a potential pipebomb in your hand. not to mention that regulated mods have longer battery life and can easily outperform a mech mod easily while still being saf

Try a dual coil 24g kanthal wrapped on a 3mm drill bit 7 wraps. comes out to 0.3 provides nice warm vape and has great flavor

A mech mod at 1 ohms is kind of a lame experience for me and a lot of people I know. I usually build mech mod coils to be around .3 or .4 (I aim for .36, but that second decimal place is usually slightly wrong). I find that's a nice warm vape (and if you use Steam-Engine, you'll see that it's actually classified as "Warm" - .5 or .6 is classified as a cooler "Warm") and it's not too hot. To do this, you're gonna wanna make 2x .7 coils (you can use Steam-Engine to calculate your coils/how many wraps/around what drillbit) or 1x .3-.4 ohm coil.

@ OP: I'd consider doing more research -- and in my opinion YouTube can be a great resource -- but as long as you stay above .22 ohms you won't be overdrawing from your battery. The Samsung battery (and Kidney Puncher specifically) is pretty reputable, and I recommend it to friends. It's always good to leave "headroom" with the amperage though. ie: You have a 25A battery, but don't think that means you should build to 24A.. Your coil may fluctuate and go down or up in resistance depending on how it's adjusted. I like to leave around 50% headroom, so if your amp limit is 20 then you should leave about 6-10A to compensate.

Lastly.. It's kind of important for us to know what RDA you're using, because if it's designed strictly for single coils (and you're building a dual coil -- somehow) you're not gonna be getting good results. The more likely situation is that you'd have an RDA designed for dual coils (only) and we're here telling you to build a single coil, which would not get great results from most RDA's (although some RDA's can cut off airflow to one coil or the other to enable single-coil mode).

So to summarize:

1. .3-.5 on a mech mod is what I aim for, it's a nice warm vape.
2. Be safe. Do some research. You're gonna get lots of different results at different ohms/setups. It'll take a while before you figure out exactly what you want.
3. If your RDA is only fit for dual coils, don't build a single coil (depends on RDA really).
4. Leave "headroom" with your amperage. Use Steam-Engine to calculate things, and always check your ohms with an accurate ohm reader!

It's a mechanical mod. Not regulated. So, I need to do some research for what coils to use on my specific mod.

The only reason I was thinking about 0.2 ohms was based on what I was seeing on youtube. I just assumed that's what I needed to have.

Well with the 28 gauge kanthal it works out to about 1 ohm single coil.
Once you get that working, if you and a second 1 ohm coil, it combines to 0.5 ohm dual coil.
