Ok I have a eGo being shipped to me right now. But I hear people talk about voltage and I have also been reading about "mah". Apparantly most common e-cigs are 130 mah, the eGo is 651 mah, and the screwdriver is 1000 mah. So my question is is this a completely different thing than the Volts? And if so what is the difference? Does the mah have anything to do with strength of the batt? Or is it more to do with the life of a single charge? Also what are the differnt voltages of batteries and do you get more vapor production from the higher voltage devices? Thanks for any help you can give.
Batteries: Mah vs. Voltage?

Volts and mAh (milliamp hours)are two different properties. If you think of a battery like a tank of water, "volts" would measure the pressure inside the tank, and "mAh" would measure the amount of water the tank contains. In this metaphor, your atomizer is a valve in the side of the tank. If you open the valve, water will come out. The pressure inside the tank will determine how quickly the water shoots out, and the capacity of the tank will determine how long you can leave the valve open before the tank runs dry.
If you vary the pressure inside the tank or the size of the valve, that will directly affect the performance (gallons per minute) of the system. It's the same with PVs. If you vary the voltage of the battery or the resistance of the atty, it will affect the performance (heat output in watts) of the device.
So any two PVs with the same voltage and the same atty resistance will perform the same, no matter what the mAh rating of the battery. The ones with low mAh just won't do it for as long.

sorry I am pretty sure I just asked a dumb question. Still pretty new to all of this. about 3 weeks in. The number on the atty is the resistance right? As in 510 or 401 ect...At first I thought you were saying you could change this by doing something to the atty. But my other question still stands. Is there any downside to getting a battery with a higher voltage?
The Number on the atty is the STYLE ( usually relates to thread size or sex ) there are variations in res. from atty to atty type and style ( Joye 510 = 2.2 ohms avg. , 901 = 3-3.3 ohms , 801 = 3.3 ohms , etc. )
They are not marked for resistance.
check out the modders/atty section I believe there is a chart over there. ?

You can't vary the resistance in one atty, but you can buy different attys that have different resistance ratings. The number on an atty is the model number. Actually, "style" number would be more accurate, since different manufacturers sometimes give different model names/numbers for the same style. For instance, you can get a 510 style atty from half a dozen different manufacturers, and they'll all have different resistances. Since these things aren't always manufactured to high quality standards, there can even be some variation in resistance between individual attys of the same make/model.
An authentic Joye 510 will measure around 2.3ohms. There are low resistance 510s that measure 1.5ohms and high voltage 510s that measure as high as 4 ohms. The lower the resistance, the higher the current flow, which means it runs hotter. Lower resistance in an atty is like putting a bigger valve on the side of your water tank.
The down side to higher voltage is that if you go too high, you will burn the liquid instead of vaporizing it. You'll also burn out attys faster. Unlike many things, "more" is not always better. What you want is the "sweet spot" somewhere between 5 and 9 watts. Some like it a bit higher, others a bit lower. But whatever your preference, you need to figure in the voltage and resistance to determine the watt output of your setup. I find this calculator takes the headache out of the process.

You cant vary the atty res. they are fixed , a Higher voltage device uses 2 batteries some are 6v some 7.4v ( batteries come in 3.0v and 3.7v ) so without some type of control they are that voltage 2x3.0=6v etc
Mod's as they are called usually have a 2 battery setup, some control the voltage to lower levels but most are fixed.
A higher voltage gives you more POWER which is what you really need to look at you can use this calculator to see the effect Ohm's Law Calculator
use a 3 ohm res. then vary the voltage on the calc. and watch what happens to the power.
It's like your household devices a 10watt or 60 watt bulb etc. this is called V/A sometimes which is Power.
Hope this helps ? I might have just confused you LOL
Ha we just really screwed this guy up Candre23 !!
