**NOTE: RC HOBBY APPLICATION RATING: 35 amps for the duration of a single 4,000 mAh battery pack with the ESC's in contact with a 5 mph airflow of 25C (77F) or cooler air. Controller temperature must never exceed 100C (212F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESCís operating temperature.
