Hello, I have recently order some things online to start building and they are set to arrive later today. I do not know what ohms to build at for peak performance, I am not looking for huge clouds I would just like a fast light up time. This is everything I ordered:

Akuma mod (clone)
AW IMR 18650 2200mAh LiMN Rechargeable Lithium Battery
Plume Veil (clone from fasttech)
Organic Japanese cotton
Also an istick 10w and 20w

I have not purchased any wire for building coils yet because I do not know what would be best to use, also I am unsure if I am going to be using a single coil or dual coils. I am mainily looking for a quick light up time with a decent amount of vapor/flavor.

Any information will help greatly! Thank you all very much.

If 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

You have a 20A battery. Off the top of my head I believe you can max it at 0.21 ohms. I, myself like a good safety margin and only build to 0.4-0.5 ohms at the lowest with a 20A battery.

Now both your isticks need to be above 1 ohm to fire.

For your 20W istick, I would probably do a single 26g coil, 10 wraps on about 2.5mm diameter. Or a single 28g coil with 6 or 7 wraps.

For your 10W istick you're going to want a much higher resistance because of the limited power. I would probably go to a 30g wire single coil. Anything less than a 2 ohm resistance will probably suffer in flavor and vapor with less than 10W.

Practice your builds with your isticks first, and set the Akuma aside for now :). The isticks have built in protection while you're learning.

I suggest building your initial coils to at least 0.8 ohm if not 1.0 ohm. The lower you go in resistance the higher the risks, so start slow & simple. Once you've gotten some experience, then go lower in resistance if you wish.

Susan has given you the resources to learn how to build coils safely. You must have an ohm reader or digital multimeter to measure your coil resistance before you even attempt to fire it. The coil must not pull more amps from the battery than the battery is rated for (continuous discharge rate). 28 gauge Kanthal is a good starting place for wire choice. Use an online calculator like Toy Coil to get an idea of how many loops of wire to wrap to. Tools which are useful can be found here.
