Hi,
I am a bit confused about what the voltage of a regular battery is?I have a 510 manual and auto battery...
First of all you should understand that a battery is rated at its
average voltage. The standard batteries are 3.7V, but actually start around 4.2V and then slope down so 3.7V is the
average.
Is the passthru the same voltage?
Kinda. There's more to it than just voltage. As soon as you connect an atomizer to it, you're placing a "load" and the voltage drops to some extent. The USB port on a computer is
rated at 5V, but it doesn't have enough amperage to run at 5V all the time so most passthrus have a 3.7V battery in the line. By constnatly charging the battery, the advantage of a passthru is that every use is like the first at that top voltage. If you have a power supply that can supply enough current, a USB "straight through" can give you 5V--but it drops down to closer to 4.5V when under the load of an atomizer.
Over time using a battery does voltage drop?by how much?
Yes, but I can't really give you a definitive answer to how much because it depends on the battery. Batteries with longer life (rated in milliamp hours) will drop voltage slower, somewhat obviously.
Why would I want a 3.7v mod over a 6v mod?
The advantage of 3.7V mod is that you get that big "first hit" experience longer. Standard mini batteries are rated for approximately 180mAH... If you have a mod and use a battery rated for 1800mAH, it will last 10 times as long.
In order to get to 5 or 6V, you usually need two batteries, so for physical size reasons they're usually going to not last as long as a single large battery. The RCR123a's that I use in my Xhaler are rated for 750mAH--considerably longer than a standard mini battery and good enough to keep me vaping all day without a recharge...but less than 2-3 days that you can get off a 3.7V battery.
What about the 280mega batteries?
They last about 55% longer.
I want a reliable battery,perhaps a mod(not a box mod...i want something that looks good!not sure how much i want to spend but i will choose more expensive if i can get smaller/prettier/not gonna break/not too hard to find parts/batteries mod but have no problem with cheaper if it does the job and is considerably less)
You'll want to decide if you want high voltage or not. Mods like the Mini Chuck, the ScrewDriver (or the Chinese knockoff 905 Nomad) and many others give you a nice long battery life but are nice and small.
Because I wanted to try high voltage, I went with the Xhaler from Nhaler as it is basically the only commercial mod that lets you switch from 6V to 5V (considered by many to be "the sweet spot"--tons of vapor and flavor, but none of the icky burnt taste you can get at 6V) and back again (when the batteries start to get low, I loosen the bottom resistor cap and I can keep on vapin!). Its also quite affordable (under $100 with batteries if you use the coupon code) and its the fastest way to get into High Voltage vaping--I ordered mine early on a friday morning from Nhaler in New Jersey, and I was vaping at 5V+ by the following monday evening (had to wait for the batteries to charge).
Now that I've gotten used to vaping at 5V, I'm not going back. I might get a Chuck or a 5V GLV as a backup down the road when I can wait to get it all nicely customized, but I've been spoiled by my Xhaler so 3.7V just doesn't cut it for me anymore.

It's a freakin' amazing vape! I let a lady-friend try mine and she put it well: "I smile every time I use this..I just can't help it!"
I have some valid and some total excuses to go back to cigs and want to spend a bit and make the switch for good...
Then you should definitely consider a high voltage mod. Quitting smoking is a lot easier if you are producing more vapor from your PV than the smoke coming from analogs. Yesterday, I was trying to test the voltage on my Xhaler, when I shorted it out...I thought I was gonna have to get through New Year's without it...fortunately Drew called me (just before midnight in his time zone) and walked me through fixing it (turns out that if you short circuit the Xhaler like I did trying to test it, the spring that holds the batteries gets hot and coils up losing its springiness, acting as a "safety" mechanism...kinda cool, but I had to open the thing up and pull the spring back) before I had the opportunity to give in to the suddenly powerful craving for an analog I got when I thought my Xhaler was down for the night.
The crisis was averted, but I did intentionally smoke one analog cigarette just before midnight for stategic reasons: I kinda quit
accidently and didn't keep close track of my last analog. By having an official "last cigarette" in 2009, I have a date to cling to. Now that we are "living in the future of 2010"

I use only my "futuristic" 5V vape machine.
any advice you might have would be appreciated especially if you have a mod and include the cons of it too
thanks

The cons of the Xhaler is that there is something of a learning curve. The button is toward the bottom of the mod, which doesn't seem natural, but becomes so with time. Brand new batteries pack an especially big punch and you do have to be careful to not let your atomizer get dry or it can burn out. The other consideration is that HV mods produce more vapor, and therefore use more juice. The upside of that is you can use less nicotine (which can be a money saver depending where you get your favorite juice) and still get a very satisfying vape. Finally, the Xhaler is currently available in 11 different color/designs, but doesn't have all the customization options available on some other mods. ...for me that was kind of an advantage, cuz I like the look of the Black Vapor design, I wasn't sure exactly how I wanted to decorate a Chuck, and I didn't want to have to wait for me to decide what I wanted and then have to wait for it to be built.
