I was running a 5S 1300mAh pack for awhile on a geared Astro motor. I guess that is 18.5V nominal, 21V fully charged.

I originally went with a 16x10 with the result of the ESC cutting off after 10 seconds or so when the battery voltage drops below 9 volts (tried two batteries).
Rick, I would really suspect the ESC is shutting down due to over temp, not under voltage. What amp rating is the ESC? Have you tried another one?
Most ESCs go into a throttle back mode when the voltage drops, they don't shut down. I also can't see a 65C 1300 pack going low on voltage after 10 seconds on a 16x10" prop.
