Product Description:
  B2E-C is a DC Brushless Motor Controller that incorporates patented technologies, including Hybrid Motor Control Technology and Hall-based position hold technology. It features in-house developed motor automatic identification technology, enabling efficient and precise control of the motor. This enhances vehicle reliability and comfort, making it a product that users can trust and use with confidence.
  It supports CAN communication and parameterized programming, making it convenient for application and maintenance. It is a high-quality product that can be used with confidence.
  Features:
  Perfect Function
   	- Supports 8 switching inputs and 3 low-side drive outputs, and various fuel inputs.
  	- The built-in regen braking control function recovers energy of the battery when the motor stops and increases time of use.
  	- The built-in motor control algorithm realize sprecise speed control, smooth starts and stop s over ramps.
  
  Safe and Rliable
   	- Superior sealing and thermal design to protect against water and significantly improve heat dissipation.
  	- Provides protection for motor and controller from over-voltage, under-voltage, over-current, over-heat, anti reverse-connection, etc, with a full range of fault detection functions.
  	- Short-circuit protection and open-circuit detection in the three low-power drive outputs, ensure vehicles safely operated.
  
  Simple and Flexible
   	- Easy wiring and installation saves labor costs.
  	- Supports remote upgrading of the program.
  	- PC programming tool provides easy parameter configuration, status monitor and troubleshooting.
