Receiver Voltage limits

So call me old school but I've always used NiMH 4.8 volt packs to power my Walkera receivers but can I use 6.6V Life packs instead. The documentation lists 4.8 to 6.0v if I'm not mistaken so I've been cautious about trying a 6.6v LiFe pack on them. Really just want to get away from the NiMH altogether. Will the extra voltage from the LIFE battery do any harm? Is anyone already doing this?

And if so, then you lose the whole model because the Walkera RX fails due to the overvoltage? Is that really worth the risk? What about the electronics connected to the receiver, like servos or an ESC? Can they handle this voltage?

What is the final charge voltage of the LiFe batteries when they are 100% fully charged? I found 3.65V, so that would be 7.3V instead of the 6.6V you mentioned.

My suggestion would be to reduce the voltage safely to 5 volts. Look for so called StepDown or Buck Converters, which always give the same output voltage at different input voltages. There are for example types with 5V / 3A.
