A bigger battery will last longer. There is no way to get around that. It will also deliver more power so you can use a lower' ohm carto.yeah true, well i have already ordered the v2 so i hope i like it, but i think ill have to just buy one of the bigger ones just so i really know the difference between them
The more power a battery sends to the coil the more juice that can be vaporized.
power = watts
More volts = more watts = more hit and vapor.
Lower ohms = more watts = more hit and vapor.
Using more watts will also drain your battery faster.
With the same voltage you will get a lot more hit and smoke with a 2.0 ohm cartomizer than with a 3.0 ohm cartomizer. To say a battery gives good smoke and hit doesn't really mean anything. It is the combination of battery votlage and cartomizer ohms that matters.
