Description 100% Brand New Features 30A: Instant 45A, 40A continuous 10 seconds Size: 30A-45*24*8mm Voltage Range: 4V-16V Battery Number: 4-12 NIMH 2-3LIPO(4LIPO BEC cannot be output) BEC Output: 30A, Stress: 5V 3A. 2LIPO 4-5 Micro Steering Gear 3 LIPO 3-4 Micro Steering Gear Protection Function: Auto Selection 2-3 LIPO is protected voltage 6V/9V. Automatically selects NIMH and each protective voltage is 0.8V. When security is initiated, the throttle position begins to protect temperature and the 110 degree downtime surface temperature is not prohibited. Uncontrollable protection, no signal for 1 second after shutdown. Property Description: Speed limit from 2 to 300,000 to 12 to 50,000 heights, very abroad, 14 to 42,000. 8KHz PWM control, speed control curve use Automatically adapts to the accelerator and is suitable for more remote control devices. BEC uses MCU isolated power supply, more stable to work. Note: This 30A cannot be programmed.
