(17) Enhanced regen brake function. A novel ABS technique provides powerful and smooth
regen.
(18) Configurable 12V brake signal input, in lieu of motor temperature sensor.
(19) Optional joystick throttle. A bi-symmetrical 0-5V signal for both forwarding and reversing.
(20) Configurable motor over-temperature detection and protection with the recommended
thermistor KTY84-130.
(21) Using battery-powered.
(22) Optional supply voltage 8V-30V.
2.2 Features
(1) Intelligence with powerful microprocessor.
(2) Synchronous rectification, ultra low drop, and fast PWM to achieve very high efficiency.
