I'm assuming the low-voltage warning is sufficient enough to allow for a safe landing should the need arise? My Futaba will sound the alarm @ 8.5v and lasts for apprx. 5-8min. Plenty of time to get in and land.

THe TXLow Batt alarm is configured based on the type of battery and voltage you program on the Tx. It does have plenty of reserve for the default NiMh voltage, but when using a 2S Lipo, it's suggested to program a slightly higher alarm voltage so the battery isn't damaged.
Airborne battery "alarm" is based on a 4 or 5 cell, and seems to be programmable only when the HPP 22 programmer interface comes out.
I run 2S 123 batteries, nominal of 6.6v, and the death spiral of a 2SA123 is about 5.45 volts, which isn't low enough to trigger the telemetry alarm in it's default mode.
But it's still nice to look at the TX and see the airborne battery voltage under operational loads.
