Chapter 2 Main Features and Specifications
2.1 General functions
(1) Extended fault detection and protection. The LED flashing pattern indicates the fault
sources.
(2) Monitoring battery voltage. Stop driving if the battery voltage is too high or too low.
(3) Built-in current loop and over current protection.
(4) Current cutback at low temperature and high temperature to protect battery and controller.
The current begins to ramp down at 90
