Voltage cutoff for 3 cell Lipo

I want to use a Castle Creations Pixie 20P with a 3 cell, 1250 mAh Lipo, 11.1V from Common Sense RC. The battery manufacturer recommends the voltage cutoff at 3.2 V per cell (9.6V total). However, the Pixie 20P program option for 3 cell Lipo is 8.4V. Has anyone else run into this problem? Can I use the 8.4V cutoff safely with the 3 cell Lipo?
What ESC can I use ?
Suggestions Please

8.4V is too low. At least 9.0V is minimum. I have my LiPo alarm set to 9.6V. Go get one.

I also set my LVC to 9.6 volts. The experts say it is important to not let any cell get below 3 volts. Since some cells discharge faster the others, I am just trying to make those expensive Lipos last as long as possible. I'm not cheap just frugal!

skylight:

You must have one in an older package since this was addressed some time ago and the industry has since settled on a minimum of 3v/cell.
You can get a great lipo low voltage device from Diversity Model Aircraft called the Li-Saver.

Another very good LiPoly LVC device is the LiPo Shield.
