Details specification as follows,

Features:
• Specially designed for electric bicycle and scooter.
• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.
• Electronic reversing.
• Voltage monitoring on 3 motor phases, bus, and power supply.
• Voltage monitoring on voltage source 12V and 5V.
• Current sense on all 3 motor phases.
• Current control loop.
• Hardware over current protection.
• Hardware over voltage protection.
• Support torque mode, speed mode, and balanced mode operation.
• Configurable limit for motor current and battery current.
• Battery current limiting available, doesn’t affect taking off performance.
• More startup current ,can get more startup speed.
• Low EMC.
• LED fault code.
• Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage.
• Rugged aluminum housing for maximum heat dissipation and harsh environment.
• Rugged high current terminals, and rugged aviation connectors for small signal.
