    What would a "No use" timer protect?

    This question is motivated by a concern with an eZip (Currie) 24V Brushed Motor Controller. But there is probably a more general question. The question is would there be a benefit from putting a timer in the controller circuitry so that if the throttle didn't ask for power for say 5 minutes...
