Can you run a 1x1' Litepanel on a Sony EX3 battery?
 

Can I hook up a 1x1' Litepanel to one of my existing Sony EX3 batteries? I don't need to tap the one on the camera but rather use a spare battery. This would save me buying V-mount batteries and chargers. Thanks!

If not, could you run CL-LED600 600 LED Panel on the EX3 batteries?

The Litepanel 1x1 are designed to run on 24 volts so the short answer is no.
Although in some of their specs they do say that they can run on a standard camera batt so it may be possible but it would probably ruin your batt fairly quickly.

The LED600 is a 12volt unit that draws 48 watts. The EX3 draws less than 14 watts so the battery is probably not up to the current draw - if it does work you would get less than 30min run time from them.

Thanks a lot!

By "Standard Battery" they mean a V-mount or Anton Bauer battery with a typical voltage of 14.4 Volts. The Coollights LED-256 run on camcorder batteries from Panasonic, Sony or Canon. The LED 600 needs at least a V-mount or Anton Bauer.
