But I agree that 14AWG should be safe for the battery with a 13.5T.
While I'm not disagreeing with you, 2/3 duty cycle is still the same order of magnitude. I believe we're in agreement that if current levels are enough to overcome the wire rating at the battery end, it's still going to be pushing the limits at the motor end. For that reason I wouldn't recommend using a lower rated motor wire than the battery wire.
