Need software support to minimize battery current when battery is under 22V or so

Need software level support to try to better inform customer of battery low. This can be oled or other indications like fast blinking leds and so on

Suggestion: once the motors stop running they should instead pwm beep in a recognisable way that can be described in the learn docs as a battery low alert.

We cannot stop current usage in the motors from host code but we can keep speed settings always 0 in this case and that will be very nearly shutting down motors and thus minimizing current draw against the battery.
