Some charge them to 7.6 or 7.4 volts. One of mine terminates at 7.2 the other at 7.4 Nothing you can do about it unless you have a fancy one.

They are safe to charge at a much higher rate than Lipo's apparently. I recall Bob (Wolf Models) telling me that his reciever packs can be charged at 5 amps (2200mAh). I've never tried it though. The most I charge my LiFe's at is 1C. Usually at .5 as the lower rate allows the balance function to work faultlessly, not that LiFe batteries go out of balance like my older LiPo ones seem to. Charge them at 1C or more and it terminates the charge with some cells at 4.25 while others are 4.15

Just be aware that the LiFe batteries have a super flat discharge curve. My transmitter tells me when my receiver battery is running low and beeps far too early when using LiFe batteries because of the load of several digital servos. 6.6 volts is fully charged and 6.2 volts is about to fall from the sky. Voltage under load can't be accounted for with my transmitter.
