Best Cloud Build For Single Samsung 25R Tube Mod?

[CrazyChef]

Like the title says, I'm curious what the best build for cloud chasing would be on a tube mod using a single Samsung 25R battery. I have a few RDAs (with more on the way ), so the best build is what I'm really interested in. I have both nichrome and kanthal, ranging from 20-40 gauge (even gauges only). I'm out of 20g N80 and 40g N80, but more is on the way.

Thanks!

Nothing personal Chef, but... I'm going to write something that you, and any others with the same thoughts, may not appreciate.

I'm glad to see that no responsible unregulated, single cell mod user has been unconscious enough to respond to your inquiry. What you're asking, considering that you are essentially asking someone to help you push a battery to the ragged edge of destruction... is dangerous, both for you, and anyone near you.

What I will suggest is that you learn the specific profile of your battery, general battery safety, Ohm's law and the associated coil optimization for Ohm's law determined battery outputs... and figure it out for yourself. You'll be glad you did.

Reading the articles at the end of my sigline hyperlinks... the Steam Engine user guide, as well as the Mech and rda user guide, where you'll find lots of good battery safety info, including Baditude's Blogs and Mooch's battery test data... will provide you with all the information you need to get started - safely.

Dude, thanks for the advice, but I already know what I'm doing when it comes to what resistance, amps, etc. that the 25R can and/or cannot handle. I'm not some f'ing teenager who's gonna put a vent burn in his mama's brand new sofa. I have a full understanding of Ohm's Law. And calculators. And my ohm meter. And Steam Engine. It was/is a simple question - single wire, parallel, Clapton, fused Clapton, alien, to stage or not to stage, etc., etc. What type of build would be best for cloud production. It's pretty simple. I can figure out the required specifications of said build on my own. Don't get your panties all up in a bunch.

I think people are getting tire of the, Whats the best coil for Steam, Flavor, steam without giving up flavor ect. Ask NEWBIE question get newbie responses.

TO ANSWER YOUR QUESTION;; Type of build = Hot and Fast........ Beyond that there is no BEST, there is what YOU like best. The key for clouds is to convert lots of juice to steam FAST. Being you are running this on a single 18650 tube mod with a battery technically safe to around 20amps. Your looking at build running at about 15-17amps for vaping safety. Thats around .3ohms or 55watts. So get the steamengine running and set it for 50-60 watts, and design a coil. The build will be different for every atty you have. Us suggesting what work in our atty, probably wont apply to yours. You got plenty of wire to work with, Go Play.

Show us what you come up with!

My current build for your type of setup is a dual parallel 28g, about 6 wraps I think, at .3ohm. In a Kennedy clone, plenty of clouds and flavor, though I favor the later more than big crazy clouds. I wouldn't feel safe building lower, and test on multiple devices before firing on my mech.

 

[CrazyChef]

So I'm seeing that any type of Clapton-esque builds aren't being suggested. Just plain wire builds. I've got a Twisted Messes RDA coming in tomorrow, so I'll have the "real estate" for larger builds. I'm thinkin' 6 wrap dual twisted 24g N80 2.5mm ID will be my first cloud build on it for the tube mod. That'll put me at about 0.2Ω and about 5 amps per volt. A little high on the amperage, but it should be okay.

Personally I just don't get the fancy coils and such; claptons, twisted... As far as I can tell all these really do is capture juice in lots of crevasses ready to heat quickly when the power arrives.

I try to design coils and wicks so that the juice flows from the centre of the wick and gradually heats as it reaches the outside. This way, beyond the first initial crackle, the vapour is practically silent and consistent through short or long draws. Increasing vapour density means you need finer vapour droplets, which means they need to be captured in flowing air quickly, so a larger external wick area and higher power work better.

All that being said, an RDA with crazy coils probably doesn't sit well with a single 25R mech tube. In my experience two small coils - like daveid777 suggests - is about where you should be aiming, and this can be done just as efficiently in a small tank. No special RDA required. In fact, because the chamber and chimney of a tank will be smaller it will probably produce a better result in both vapour density and flavour terms.

In short, I think either more efficiency is in order (small dual coils tank, UD Goblin Mini?), or more power (proper twin battery box mod) depending on your preference.

Agree wholly with Kman - cloud chasing and standard level devices don't exactly mesh together, otherwise its all about the chamber efficiency that plenty of standard dual coil tanks provide these days. Past that it's just power and wicking efficiency to be able to keep up.

Dual Parallel 24 ga Ni80 works well for me. I like parallel better than twisted for sure. I build 3 mm wicked with rayon. Build to your own desired resistance level...

I can chain vape the hell out of these and get 7 or 8 good full lung hits out of my MutX V3...on a mech with 25rs

 

[TheKman]

How many turns? Assing 6, for the sake of argument, that puts you well beyond the current limit of a 25R.

Edit: Sorry, 25Rs... Two, not one, yes?

Finding coil builds becomes intuitive after some experience. After doing a few builds and seeing how a single battery mechanical operates you will get a feel for what to do for what application.

I would use steam engine and set your resistance, then calculate the wattage for heatflux based on the voltage and resistance. From there you can play with wire gauge, coil type, and coil ID. The heatflux will give you an idea of how that coil is going to perform. I'm sure you know not to set the resistance too low since you are working with only one battery.

You should get in the habit of choosing your resistance first, then picking a wire that will work best at the voltage you want to give it.

I also want to mention that builds will perform different in different atomizers. Chamber size and how air comes in contact with the coil plays a role. Tight chambers usually result in denser vapor.

 

[TheKman]

What I'd like to see from Steam Engine is an aggregate of the various calculators into one page. Select your mod/power or mech battery, select target heatflux, select coil material/configuration... output number of turns with ID options and any possible warnings/errors. How awesome would that be? If it also understood the voltage/current transfer function for a selected battery that would be the ultimate. Even integrating a batteries estimated internal resistance into the calculations - perhaps plus a mech's resistance - would be a great advantage for design purposes.

I do all this work by hand at the moment... how nice if someone else could do the hard work for me.

A single 18650 mech with a 25r is fine down to 0.2, like also the OP sugested. No reason really to go much lower than 0.2 on any single 18650 mech/battery-combo though imho, as you're not really going to get the output that you think anyways ...

(0.2 equals 21a only right at the start and climbing down to 18 or below(4.2>3.7)... The 25r is pretty cool also around the 20a line according to Mooch's testings)

Crazy crazy crazy, cook up some parallels, 24g KA1/40g Clapton parallel to 24 (or 26g) N80. 2.5mm-2.7mm to get surface area. How ever many wraps is up to you. Staged heating & what not + good cloud production.

Going straight to Steam Engine - thanks Tom!
