Coil Question

[branden]

I have a Druga mech mod and rda with a single 18650 3.7v battery, i want to make just a single coil build (either parallel or normal) and im using 24g Kanthal, which ive heard isnt the best, but im wanting to know the general ohm i need to stay around...and preferably the best build for it (with 24g kanthal) Thanks

This question is impossible to answer without knowing more about the battery. What brand, mAh, and Amp rating does it have?

fair enough....its an AWT imr 18650 3.7v 3000mAh, 50A single battery

A single 6 wrap 2.5mm will yield about a 0.5Ω build and will be safe on that cell.

right, what about a parallel? or is that pushing the limits?

 

[Shawn Hoefer]

The same specs in parallel will yield half that resistance... Still safe. You can build down to 0 21Ω without too much worry.

acouple more questions, sir....1: does single airflow mean the coil will go out faster or vise versa? and 2: does the parallel rule (half the resistance) also apply to dual coils?

What do you mean by single airflow? If you've got a single coil, use single airhole. If you've got duals, use 2. Unless you're using one of those dual or single coil decks wherein the air comes from the bottom. Getting less air to the coil can shorten the coil's life if that coil is being used at high wattage without adequate air. If being used at lower wattages or for a cooler vape it might be fine.

Yes, 2 coils halves the resistance.

Might I gently suggest you do a bit more research on coils with an emphasis on ohms law before diving into mechs...

I suggest you research here before doing anything with that mod (18) Baditude's Blogs | E-Cigarette Forum

Ive had this box for awhile, along with the rda...and im aware of my batterys capabilities (because ive looked everything up multiple times) but everytime i looked up “what is a safest ohm/build for [my battery]?”, it either pulled up a “Vaping Ohm Chart” or said “most people like 1.5-3.0 ohms”, but i knew it didnt go that high....thats the exact reason i made a profile on here and asked, because thats the only part i was confused on (plus i have an ohm reader app and no number of wraps went past 1 ohm per coil) but i appreciate the concern, and i do plan to read up more on everything

There really is very little margin for error with mechs, blindly fiddling can result in injury.

Use steam-engine to model your proposed build, calculate what the amp draw will be and then pick a good quality battery that has a CDR that will support that. Ideally with some headroom.

Your AWT is not a good battery. Mooch tested it to be a poor quality 15 amp cell.
Bench Retest Results: AWT Black 50A 3000mAh 18650...obscenely overrated, do not buy

yeahh, the battery sucks....but its really all i have rn, but thanks for the links and things

The battery is the heart of any vaping system, especially in a mech.
If you can't afford a better one now, make sure you stay over 0.3 ohms with that AWT until you can.

Replacing that battery should be #1 priority, quality batteries are cheap.

 

[untar]

make sure you stay under 0.3 ohms

Over... make sure you stay over .3Ω
