I believe that is on the hairball not the controller. You have three battery settings on the hairball:
BA is the Battery Amp limit. • LBV is the Low Battery Voltage limit. The controller will automatically reduce current so as notto run below this. • LBVI is the Low Battery Voltage Indicator. The battery light on the dash will lightbelow this level.

This discussion specifically concerns a vehicle using a Zilla motor controller; from the Z1K specsheet: "Other features include programmable motor voltage and current limits, programmable battery voltage and current limits, adjustable low battery voltage protection and an additional low battery indicator output." > It may have a low voltage cutoff circuit but that just shuts down the > output in the event the battery falls below 72volts.... thus the > controller would not be working if the voltage was 96-72 = 24volts. Even this simple case would achieve the *same* behaviour: the controller would PWM "willy-nilly" until the input voltage sagged below the minimum input threshold, then it go to 0% duty. As soon as it went to 0% duty, the load on the battery would decrease, and the input voltage would rise slightly above the minimum threshold, and the controller would resume PWMing. Resuming the load would sag the input voltage below the threshold again, and the cycle would repeat such that the input voltage is regulated in a sawtooth manner at the minimum voltage.
