Benjamin added a new Feature called Acceleration Temperature Decrease.
This feature allows you to leave temperature headroom for the brakes to work. You simply can't push the motors or VESC or both to their absolute pre-defined temperature limits any more. In consequence the brakes will still work, even if you push your system to a soft power cutoff during your ride. Please download the latest VESC-Tool and update to the latest firmware! Stay safe and implement this feature.
