new to cloud chasing...

[coltonjr2]

Hi, im new to this.. BUT i have done endless hours of research. I have an m6 mod, awt 26650 battery, and tobeco rda.. i have an alright understanding of ohm's law from College, but i guess what id like to know is what my resistance safe zones are for coil builds, and if anyone can give me any knowledge towards chuckin massive clouds.

Thanks!!

There's a great set of calculators here:

Steam Engine | free vaping calculators

It seems to me that the big clouds are a balancing act between resistance, coil surface area, and heat flux. The Battery Drain calculator will give you your amp drain limits. Common batteries are already pre-set in there, too.

Tobecco makes a ton of clones... and a Turbo RDA, and some other stuff too... if you state what style of RDA you have, it would be easier to recommend a build.

Is your battery 35A continuous? You didn't list any specifics on that either.

Yes let us know what Atty, we can hook you up

I don't know what the CDR is of your AWT battery. Many rewrappers "mislabel" their batteries with the "pulse" rating. Check out these blogs by @Baditude (one of our resident battery/safety experts).

I'll give you an example of the rule I follow using a 30A CDR battery. Everyone is free to set their own parameters, and I can only say what mine are.

I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 30A battery, that would be 15A. This Ohm's Law Calculator tells me that a 0.28Ω 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 30A battery may only be a 15A battery.

Thanks a lot to all of you, im unsure which atty it is, but the af holes are shaped like an x with a bigger hole being the middle one if that helps haha, and my battery is 75a

Well with the battery I'd say your easily good to .25

Def play with steam engine

I'd probably use 24g - 28gfor dual coils.28 for .5 n up gauge goes down as resistance goes down

The trick with a mech is reaction time But use too much wire and you kill the reaction time meaning too heavy of a wire or too much wire and the battery struggles to heat all of it

So its a balancing act of how much wire can I get to heat up quickly before its too much.

The lower you go on resistance the quicker the battery dies as well.
I'm no a full on cloud chaser so I'm around .4 dual to .8 single depending on the Atty and I can fog out no problems.

If you check out our rebuilding section you will see a huge amount of build and coil types to play with

Okay awesome! im at 0.27 on the build i have right now, and just to understand a little better, what if i did a single coil build, with 22g kanthal, and between 4-6 wraps, would that work good for clouds do you think?

 

[Thrasher]

Check steam engine I don't know if 4-6 of 22 will come up high enough

Something else with dual coil don't forget power is split .4 single is going to full power .4 duals would be power divided by 2

So a dual at 50 watts is 25 each, a single at 50 watts is full power on half the wire so you can add a few more wraps


There is no perfect answer.
Ideally more wire = more surface area=more vapor.
But in the real world it may not always follow a theory
You just have to play and experiment with different setups and types of coils.

I do dual coils with 22g sometimes on my unregulated mods. Usually 6 wraps each around a 2mm screwdriver. It'll come out to around .15... which is still going to work fine with your 26650, which is probably 35A continuous drain. Just make sure you do it right.
