i mean if you have 2 different ecigs that are 3.7 and 2 cartos that are 2 ohm,the only difference is the battery life. What makes some better than others?
3.7 volts is 3.7volts right?

Bigger is better. If you have a 3.7v 3000mah 18650 battery and a 3.7v 900mah 14500 battery they should be equal in voltage when they are fully charged. They may even be higher than 3.7v. But, as the charge goes down the voltage drops. After an hour of vaping the 18650 will probably be close to its original voltage, but the smaller 14500 will have dropped lower. Assuming that they both started fully charged at 3.7v the 18650 will likely still be there, but the smaller 900mah batt might be at 3.6v. After 8 hours the 3000mah batt might be at 3.5v while the 900mah batt would probably be in the lower 3v range. So, basically larger capacity allows the battery to stay at a higher voltage longer. Higher voltage allows the atomizer to work quicker and get hotter, providing better vapor production.
Also, batteries with higher C rating have a longer life and handle LR atties better than those with lower C rating. AW lithium-ion batteries have a C rating of 2.0, other brands are lower. There are lots of threads on this forum dealing with the technical details of this.
AW batteries tend to have a higher C rating than most others. This means the amperage output is greater and can better handle an e-cig atomizer or cartomizer that demands this higher amperage. This is why you can vape a LR atty on a 3.7V AW brand battery and have less concern of over stressing the battery compared to a standard proprietary battery such as a 510, even though the voltage output may be the same.
An example : try a 3.7v 808 battery fully charged, and then a 3.7v 18650 high-drain fully charged, the difference was immense for me. And for anyone with a 510 or an eGo, those batteries drop to about 3.3v under load so the difference with be even greater for you.
Yeah, and reading them can actually cause epileptic seizures.
Lol! That made me smile inside.
If two devices deliver the same voltage to the same atomizer *under load* then they will give about the same "vaping experience" (I hate terms like that but I'm sure you know what I mean). The thing is voltage under load is rarely measured. Voltage under no load is almost useless. It tells you the state of charge of a battery (if there's no regulator acting on the voltage, often sealed factory e-cig batteries are regulated, and occasionally mods) and that's about it. As mentioned already, different batteries have different abilities when it comes to delivering larger amounts of current (Amps) and these differences would only show up when the battery is loaded. Different devices might have varying levels of resistance in the switch and elsewhere (resistance in a switch or whatever will reduce the amount of current able to get to the atomizer) which again will affect performance under load. However, they would all still simply show the battery voltage when tested under no load.
Although none of this is rocket science, it's really not quite as simple as two devices running the same voltage batteries will always perform the same.

excellent guys.I understand now. To think im a general class ham operator and failed to remember this is beyond me.. Im now pumped about building the 510 box mod
