I don't know how it acts at full throttle... I don't think I have ever gone full throttle. I am using a TP 1320 13c/20c. All I know is, it still has plenty of power to hover when the battery is dead. That's why I am using the lipo alarm, I don't want to take any chances. Maybe the TP batteries are a little lighter or something. I have been flying until the battery is at about 10.2 volts. Maybe I should raise the voltage on the alarm a little higher.
