July 4, 20178 yr The controller on my S-Cross CB states the low voltage protection cut off is 31.5V . I don't think the voltage on the display is totally accurate, I've had it read 41.5V hot off the charger but a multimeter across the terminals gives 41.8V.
July 4, 20178 yr All controllers tend to have a low lvc, however the batteries bms's lvc is usually higher to protect cells so this will over ride the controller.
July 4, 20178 yr It's normal to have a damping factor in the LCD's battery display. That's to stop the numbers going up and down every time you open the throttle. Also, after cutoff, like any battery, the voltage will recover a bit. The only way to find out what your cut-off is, would be to measure the voltage in real-time at the time it cuts off. It's most likely 31v.
July 4, 20178 yr the battery and controller cutoff is 31V but because of the voltage sag, you will see the motor stuttering at about 33V-33.5V. the bottom 20% of the battery capacity is difficult to ride with.
