This not only increases the run time of the unit but also prevents me from being blinded by the display in a dark venue. I also lowered the overall display brightness from 100% to 70%. Everything ran fine with no lightning bolt or CPU throttling. I ran some load testing by hooking up all the peripherals and running a large MODEP/SunVox session.
