Default How to make the GPU stay in Performance Level 2 on battery?

PowerMizer is preventing me from viewing smooth HD video playback while unplugged from AC on my laptop. While connected to AC, videos play fine.

nvidia-settings shows PowerMizer has the following Performance Levels:

PL | Graphics Clock | Memory Clock | Processor Clock

0 - 50 MHz - 135 MHz - 101 MHz
1 - 202 MHz - 324 MHz - 405 MHz
2 - 675 MHz - 1250 MHz - 1350 MHz


When I'm connected to AC power and view an HD video, PowerMizer shows that Performance Level 2 is used. When on battery only 0 & 1 are used. Unfortunately PL 1 isn't fast enough to view HD. How can I force PowerMizer to be allowed to use PL 2 while on battery?
