I like the time delay operation of the RC using just the backup battery. We used it pretty extensively to test over in the programming corner without having to setup a 12v power supply. It was also handy just dropping new programs in without having to power-up the rest of the electrical sub-systems.

You can use the User Mode display on the OI (or the dashboard) to display the backup battery voltage, just like the main battery display. You just need to use the matching code. I think the default code was setup to display it.
Code:
#define backup_voltage rxdata.rc_backup_batt*15.64/256
It does have that floating-point number that you might want to shift out of the way.
