New Dreadnaut not firing

[dreadnaut]

So I've finally gotten around to firing up my new Dreadnaut clone and it's not firing. The battery, an EFest IMR 26650, is fully charged and I checked it with my meter. I load the battery, positive side up, and push the button, but I'm not getting anything. Any tips on what could be the issue with it? I'm not new to vaping, but I am new to mech. mods.

Thanks.

Check center post on 510 connector make sure its making contact with battery. Also check center post of addy you may need to lower screw.

The contacts are definitely making contact with the battery. I screwed down the center post on the atty as far is it goes, but still nothing. Is there a safety mechanism on this that could have been tripped at some point.

Maybe I'm missing something here, am I supposed to put my own coil across those three posts?

Yes. It needs wick and juice too.

It sounds as if you are new to mech mods. First off read ohms law and battery safety. Yes you need to build coils there are many tutorials on youtube.

I feel stupid. I got the wick and the juice parts, but can someone point me to an article on building coils for this thing. I've made coils for small electronics projects, but I'm not sure what I'm supposed to be going for for ohms on this. I don't want to push any boundaries here and blow up my hand. My battery, the efest IMR 26650 says it's discharge is 20A/50A. I think that should be sufficient, but need a bit more help on the coil part.

You ARE pushing TWO boundaries:
1: You are new to mech mods; that's one; no problem.
2: Apparently you are also using an RDA, which you have not identified.

If you "don't want to push any boundaries", then do not try to rush TWO steps at a time.

this is just a tutorial on how to build coils https://www.youtube.com/watch?v=rk637J_9KSc

Not stupid at all, we all had to begin somewhere.. I suggest you look over this thread, and watch the vid in the 1st post.

http://www.e-cigarette-forum.com/fo...-discussion-safety-battery-info-warnings.html

There is also a Kanthal wire gauge / ohms per inch chart there. Read, watch, and become comfortable with what you're wanting to accomplish. There is a forum here discussing coil builds:

Coil Builds

If you have more questions, be sure to ask..

EDIT: Just because the thread is geared toward sub-ohm, doesn't mean you have to.. The info pertains to any build really. I would suggest maybe shooting for a 1 ohm coil to get your feet wet..

 

[dreadnaut]

I built my first coil and it's 1.7 ohm and it seems to work totally fine. I ran some juice through. Blew some huge clouds. I checked the battery like four times to make sure it wasn't getting hot, it didn't do anything strange.

So if I went with a 1 ohm coil, would be the result? Would it burn hotter and faster?

Also I can put two coils in this dreadnaut what's the upside and downside to running two. It seems like it would run the battery down more quickly and burn through the juice faster, which I guess could be a good thing if you're in a hurry.

Since you are new to mech mods and rebuildables I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:

BATTERIES

Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

MECHANICAL MODS & REBUILDABLES

Information Resources for Your First RBA
* An essential read and reference guide for someone new to rebuilding coils. Includes a multitude of useful links on battery safety, mod safety, coil meters, coil building, and the differences in the three types of RBA's.

Inexpensive Mechanical Mod/RDA Setup
* A response to the frequently asked question on how to get into rebuildable atomizers with a mechanical mod inexpensively. Includes a list of commonly used tools and supplies for rebuilding and where to find them.

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

I try to never exceed 50% of the CDR of a battery. So with a 20a batteries, that would be 10a.
This Ohm's Law Calculator tells me that a .4 ohm build is as low as I would want to use.

The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades, so does the batteries c rating (amp limit). So down the road, my 20a battery may only be a 10a battery.

It looks like I was right to go with 1.7 ohm coil. Using 1.7 + 2 = 3.7 which is the volts of my battery. So I feel like I'm in safe territory with my battery and coil setup. I'm still curious though about dual coils.

Interesting though, I rechecked the posts, which became loose and the resistance which dropped to 1.5 ohms. So the tip about rechecking resistance was super useful.

 

[dreadnaut]

I feel like 1.5 or 1.7 ohms works fine, so I think I'll stay in that range. I don't feel the need to push the envelop.

That sounds like 30 guage kanthal.

 

[dreadnaut]

Close 28 gauge.

 

[edyle]

Close 28 gauge.

1.5 ohm 28 gauge kanthal at 4 volts sounds a bit high. Probably sluggish to warm up.
with 28 gauge at 4 volts, people usually wrap 1 ohm per coil.

I've got a couple wrapped at 1.2 , 1.3

But mostly I use 30 gauge at 2.4 ohm per coil
