Features: Suitable for Electric for electric bike & scooter Rated Voltage: DC 72 Volts Rated power: 4000 Watts Casing material: aluminium Maximum Current: 85 A 1Amps Under-voltageprotection: 63V The speed limit options: external jumper selection Thermal: aluminum shell and the substrate 3 phase 120 brushless motor Operating Conditions: -20~45 C Waterproof design Weight:5 kg Functions: Mute when start Speed limit Power cut brake Blockage protection Current limit protection Short circuit protection Avoid out of control 1:1 pedal assist function Undervoltage protection Self Learning: The Super mute function:Optimizing the design of motor and the control strategy, make the motor run with low noise,low oscillation and high output torque. Unique thermolysis function: With the advanced aluminium base heat technology to improve the effect of heat dissipation and the load flow of power component. Undervoltage current limiting function:Approaching the undervoltage,controller can lower the output current by itself to ensure the voltage above the undervoltage point, until the real voltage stop output. It can not only protect the battery effectively,but also increase the mileage.
