Right now I have a Nemisis & Trident V2 Clone. I bought 2 EFEST IMR 18650 2000mah 3.7v High Drain Li-mn batteries for it. I also orded some 28 gauge Kanthal Wire. I know how to rebuild but I do not understand all the ohms and all of that. So what I need help with is how should I build my setup with the batteries and wire I orded. My main concern is the battery blowing up if I do it wrong. Also I have one of those standard chargers for different size batteries. Is there anything I should be worried about or can I use that charger?

You really needed to provide more information than you did. Concerning the charger, what exactly is a "standard charger"? A name and model number would have helped a lot.
As with batteries, if I can not identify the manufacturer or the model number, I won't use it. The same goes for chargers. There's too much cheap and unsafe stuff coming from China to risk your limbs or home to a fire. Use only name brand and reputable gear from a reputable vendor source (ie RTD Vapor).
Do you own an ohm reader or a multimeter? You will need one to measure the resistance of the coils you make. This item is an absolute must. There's no room for "guessing" the resistance just by the number of wraps and the gauge of the wire you use. This is critical.

Once you make your coil and measure the resistance (ohm), use the Ohm's Law Calculator to find the amp draw the coil will pull from a battery. Use 4.2 volts (fully charged battery's voltage) as the voltage and the ohm of your coil as the resistance. Then click calculate. The "current" will be the amps that the coil will pull from the battery. This must not be equal to or in excess of what your battery's amp limit is. This is critical.

Your Efest 18650 2000mah batteries have a 10 amp limit. Therefore, do not build/use a coil less than 0.7 ohms with those batteries.

The charger says
Li-ion Battery Universal Charger
Model: YCD-1688
Imput:AC100-240V 37-63HZ
Output: 3.7V/500mA
End-of-charge voltage: 4.2V±1%
Thanks for the help!

So the company is so ashamed of its product that they don't even put their name on it. Yeah, that more than convinced me that its a great product and safe.
That's a unknown charger made by an unknown manufacturer of unknown quality. I'd personally put that in the garbage and be looking for a Pila, Xtar, or Nitecore charger from RTD Vapor.
