Hey guys I'm new to vapeing and my local Vape shop talked me into getting a k100 with a zenith v2 rda. For a few weeks I have been taking it there and they build the coils for me but I want to start building my self. I don't know anything about this so I will accept any tips or advice on building coils. So any suggestions?
Coil builds?

Wow, another Vape shop doing a disservice to a new Vaper. Ok, first things first do you have a Digital Multi-Meter (DMM) or a least a $20 Ohm reader from the Vape shop? Also, what kind of batteries are you using? What kind of charger do you have? What is the resistance of the coil they set you up with?
http://www.e-cigarette-forum.com/forum/coil-builds/416271-micro-coils-increase-vapor-flavor-th.html would be the best place to learn how to build coils competently.
I have a old DMM from school. I have a efest 35a 18650 and 2 IMR 10a 18650s. The charger is a trustfire multifunctional charger. I don't know the resistance of the coil. It is made with either 22 or 24 gauge wire and has 6-7 wraps
you have a multimeter.... but dont know the resistance of your coil........
/facepalm

The imr 10a will be no good for any builds with 22 or 24. the efest is a 20 amp rated battery that will work fine for most of your needs. You could use an upgraded charger like an efest luc, nitecore, or xtar. Get something to check your resistance levels so you dont blow a hole in your hand or the side of your face
check it, report back, many wonderous things will be discerned.
By telling us how many wraps, and the resistance, you can work backwards with coil wrapping calculator and figure out the other part of your questions.

Alright, so you're somewhat set up. The ohm meter is a must since you need to know the resistance of the build you are using. Most DMMs have this capability. If yours doesn't or you don't trust it, you will need to pick up a separate ohm meter from your local Vape shop. Since you are using a mechanical mod, you will also need to check your battery voltage. Luckily measuring DC voltage is easy to do and your DMM should work fine. The charger should quit charging at 4.2V (double check with your meter and don't let the batteries sit in the charger after charging is complete) and never drain your batteries below 2.5V. For safety sake and battery life try to replace them between 3.3-3.6V.
While you are at it, if you have a smart phone, get either Stream Engine or Vapor's Toolbox. You can play around with different settings to see what kind of build would result in what resistance (or close). Don't build ANYTHING until you have the means to test the resistance and check for shorts. Based on your batteries, don't build below 0.5 Ohms and I would suggest staying above 1.0 Ohms until you get comfortable. Once again, you will need to be able to read your resistance before you can get started.
Search for Baditude's (resident battery safety expert) blog about battery safety and read, read, read! Let us know when you measure the resistance of your current set up that the Vape shop built for you.
Edit: Buy a new DMM, just saw that your is broke. And if your mod is getting hot, that's bad!

You mean the mod or the topper, is getting hot?
mod = battery holder
topper = rda/rta
I take it you mean 0.15 ohms, correct?
If so, that resistance will draw 28 amps from the battery when the battery is fully charged at 4.2 volts. None of your batteries are good enough to support that much current so they will heat up. The 10 amp batteries are downright dangerous at 28 amps. Get them too hot and they go into thermal runaway and they'll vent.
I suggest you stop vaping that build and either go back to the shop and ask for a 0.6 ohm minimum build or rebuild it yourself.
I highly recommend you spend some more time with Baditude (our resident battery expert) 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 (if you don't already have one) and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

BATTERIES - WHERE TO BUY
How to Spot Fake Sony Batteries
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
That's what I was thinking. I just bought some stuff to make my own it should be in this weekend or early next week. I had a feeling it was really low ohm because of how hot my topper and k100 were getting. But the weird thing is that my batteries did not get hot at all. I just bought a ohm meter some 28g kanthal and a xtar vp1 charger. Next on my list is a Sony vtc5 battery and possibly a new mod
