Sigelei 150 w/Mutation V3 Coil issues

[Josh Lego]

Hello all! Im new here.

My name is Josh, and Im an O level Aircraft mechanic, that enjoys tinkering with things. Which is why I originally started building mods. I've had a lot of issues with clones and finally decided to get an original sigelei 150w. Previously I've had the vape shop in San Clemente build coils for me, but this also costs extra money. When I can just do it myself. Im going to give you the most information possible to help solve my issue.

Currently, I am running a Dual Coil build. I tried to find a similiar post, to mine. But it seems that each one is unique, and different depending on the individual's setup.

I have 4 posts on my atomizer. Which is the Mutation X V3
They look like this and ill be using this reference to help build the best picture of my issue.

"1.23.4"

I am running a 24g Kanthal wire, with 10 wraps, around a 3mm screwdriver.(As instructed by local shop) With the following:

Coil 1: Connected to posts 1/3
Coil 2: Connected to posts 2/4

Currently, as of today my mod is at 6.6v-7.5v 1.5 Ohms @ 40.6w This seems ridiculously high to me, which lead me here.

My Battery info is the following:

Manufacturer: NXJO
IMR: 18650
Volts: 3.7v
MAH: 2500
35A

This is a married pair.

For wicking I am using Organic Japanese cotton, I am also not over stuffing my coils.


My question is, what is wrong here?

Do I need to rebuild my coils? If so, how many wraps @ 24g (Kanthal)/What size coils? 3mm 2mm ect.

Do you need pictures? I can provide those as well.

I just dont have a good feeling about what the output on my vape is telling me. Im an O level mech, I feel like I should be able to figure this out, but vapes are foreign to me. I use 3mg Juice as well. I just enjoy making large clouds more than I do the actual nicotine. But i want to be able to do so safely, without blowing my hand off. Until this issue is resolved, I've currently taken the batteries out of my Vape for safety reasons.

My goals with this mod are, thick clouds, minor throat hit. I don't need the high nicotine content that some other users do. This is also becoming a hobby for me.
Its funny sometimes, that you can fix an airplane. But you cant fix a metal box. Haha

I will be doing my wraps by hand as well, unless another user has a better suggestion.

Thank you for your help.

Incredibly hard to get this post up. It kept telling me that I am not allowed to post links. -____- I wasnt even posting links!

What problem(s) are you having?

 

[Josh Lego]

^Brandon, currently i feel that the voltage isnt safe, and that the Ohms are too high. They're hovering between 2.2ohms to 1.5ohms. I've been reading that I need to have around 0.3-0.5 when running a dual coil setup. Steamengine recommends 0.347ohms.

I have 2 coils, wrapped 10x w/24g Kanthal.

 

[Josh Lego]

I guess my last post would be the TL;DR version.

I've not been building coils very long myself, and I hope someone who knows more than me chimes in soon, but it seems to me that if your ohms are fluctuating, you have a problem somewhere. Maybe one of your wire legs broke off inside the screw post, or you have a screw that isn't tightened down enough. I would be worried about the resistance fluctuating, that is not good.

If you feel uncomfortable then feel free to build at lower ohms. As long as your batteries can handle the voltage then you're safe. That is a fairly high voltage but you're not exceeding your device's limits.

This is good advice. A fluctuation of ~.1 ohm is normal.

Question: How many wraps do you usually do with 24g Kanthal to achieve, say around 0.5 ohms? In a duel coil setup.

 

[Josh Lego]

Id say this fluctuation is not normal, its fluctuating around 1.0-2.2 ohms. I wish it was just 0.1

Question 2: How do you wrap your coils, do you do so by hand. and what MM are you using? 2mm? 3mm? a Drill bit tip?

 

[ElevenEleven]

Hey, Josh, make sure your coils are tightened down.

 

[Cacique]

I use Steamengine to determine how many wraps at what size. I just punch in the type of wire and gauge and the desired ohms.

I wrap my coils either by hand using a screwdriver-like jig or using the Artistic Wire coiling gizmo. I also try to wrap them as tight as I want them, but usually have to play with them a little bit to get them firing evenly. Good luck!

 

[Kiwi5400]

New forum member, but I've been building coils for a while. From what I've read, the Mutation requires the screws to be tight, or they'll back off on their own. On the flip side, over-tightening the screws can shear the coil's leg, either of which would give you a bad connection. A jump that large would suggest to me that one of the coils isn't forming a proper connection.

 

[BeerGolfClouds]

Welcome!

First, like others mentioned, you have a bad connection somewhere. Either the coils are not secure to the posts or the RDA is making iffy contact with your mod. To get 1.5 ohms out of a dual coil 24ga 3mm setup, you'd need 33 wraps per coil! Which leads me to my second tip...

Get steam engine! It's online and in the play store. It's an invaluable tool for wrapping coils and a whole lot more. It tells me that your current build should be right around .5 ohm, so some careful tightening should do the trick.

Lastly, your batteries are 35 amp PULSE rated, 20 amp continuous. That's fine for most applications, but I believe the 150w and up devices recommend using 30 amp CDR batteries. At least mine does (iPV3). Hopefully someone can post all the usual battery links, but I'll give the short version. Go to orbtronic.com and order the sx30. True 30 amp CDR and you won't have to worry about whether it's counterfeit or not. Get flat top, not button top.

Question: How many wraps do you usually do with 24g Kanthal to achieve, say around 0.5 ohms? In a duel coil setup.

I do 8 wraps of 26g on my screwdriver to get between .6 and .7 ohms, which is about my sweet spot. I have never used 24g. I have an IPV mini v2 and I tend to run it between 38 and 45w. I am not sure which size screwdriver I am using, it is the largest one in my kit of 5 little silver handled screwdrivers from Harbor Freight, which I realize is a stupid statement but it's not marked anywhere and the package is long gone. That is just the size coil that works best for me to wick it how I want it.

Also, I missed somehow before that you were using a Mutation. Is it a clone? My mutation v3 (clone) has an adjustable bottom 510 screw. I do not have any problem with mine making contact with my mod, but if I don't unscrew the bottom 510 screw a little bit so that it sticks out it will not make contact with the 510 connection on my ohms reader. If you find that you haven't broken one of your legs off in the posts, or your screws aren't loose, you might just need to adjust that bottom 510 screw a little so it makes good contact with the connector on your mod. You don't want to screw it all the way out, just a little so it makes a more solid contact. I don't know what your mod's 510 connector looks like, but that might help.

Last, I have noticed that of all my RBAs, the Mutation for some reason seems to be the one that needs the most re-tightening after you fire the new coil and squeeze it. It may just be the way the screws are made. I'm assuming that you know to do this (fire the coil till it glows then compress the coil with tweezers or something similar, making it tighter and checking for hot spots etc). I always have to give it a good re-tighten after I've done that. If the screws are a little loose after this, once you wick it, it will cause the coil to fluctuate weirdly like you are describing sometimes.

Yes! Came to post almost exactly this.

Here's Steam-Engine.

Had similar issues - see my latest thread. I will say the screws on the Mutation X V3 and V4 are a bit funky (the bottom of the screws). YOu have to tighten/loosen to see if you can get your voltage to stabilize. Please keep in mind you're running two batteries. 6.6v = 3.3v per battery.

Lower your wattage down to around 40w. It is safe in that range, your are using a regulated device.

Sorry to the OP, this post is old, but I wanted to comment. I have the same issues to this day! I run .1 - .3ohm builds, and I regularly have my voltage set to 5.5v - 6.6v around the 40w - 60w range when doing 2-coils.

When doing 3-coils like in a Stillare V3 RDA or an Onslaught, My sigelei fires around the 75w @ 3.9v range. You'll notice the voltage will change with the RDA you use, but the problem of voltage jumping begins at how your coils are attached/making contact with your atomizer.

I'm just saying even at the 6.6v range you should be fine, youll just deplete your battery fast. I would recommend rebuilding your coils, the same amount of wraps, but try tightening the screws down all the way - or tighten them JUUUUUSST until they make a connection.

The other option would be to switch out the stock screws with grub screws, and that should definitely solve your problem.

Um, what? There's a fair bit wrong with your post, but I'll address primarily this.

6.6V to a .1 ohm coil is 66A or 435W. So... what?

Even at .3 that's 22A and 145W. While not impossible, that'd be an unavoidably hot vape.

Do you own a Sigelei and Mutation X V3? Just curious if you actually have the setup we're talking about. Because I TOTALLY understand what you're saying... it doesn't make sense... but... that being said:

With the Mutation X V3 on a Sigelei 150w box, I can assure you most of the time if I do a .3ohm build, I will move my wattage down to 40watts, and the voltage will read 5.5v, if I bump it up to say 55w - 60w - I'll be well over 6v.

You'd think at 6v it'd be incredibly hot right?

Nah... its not really... whiiiiiich if you read the post, you'd see that clearly something is wrong... the vape at 60w 6.6v is actually quite nice. A little on the warm side..

I went in to my brick and mortar vape shop locally and they said not to worry, regulated device, something going wrong with the connection to the coils causing the voltage to spike, but they've read from the manufacturer that sometimes voltage will double (combine the voltage per battery)... aka... 6.6v is 3.3 volts per battery since it is a dual 18650 box mod..

I know it doesn't make sense, I'm not trying to state facts here... I can only tell you the truth based off my my sigelei and my mutation X V3... and turns out I'm not the only one with this issue. Nothing crazy has happened and I've vaped my batteries (authentic VTC4's) down to 20%, and then recharge... no problems. Like the guys in my local vape shop said, it's either something with the connection to the coils... or.... something wrong with the chip.

However, the thing that makes me think its atomizer related = the moment I put in a different atomizer - the problem goes away. and I start to get normal readings

next post I'll take pictures...
