Ummm......
There isn't a good way to volt check LiFe/A123 type batteries as the discharge curve is very flat right up to where it falls off a cliff and dies. So with that chemistry, you fly them by time e.g. determine what your average usage is per minute and recharge when you get to about 50% is what I do. Don't go more than 80% used.
I would suggest you spend a bit of time in probably the radio forum for some more input on these batteries.

As Zeeb said, you can't go by voltage, only mah used. You can either get some sort of mah counter, I use a Booma RC switch, or charge, make a normal flight, then recharge, divide that number into 1800 (50% of your pack capacity) to find out how many flights you can can safely make before needing to recharge.
