Two arduinos one battery?

I can't seem find anything anywhere about how or if its possible to run two arduinos off of the same battery source. This might be a simple fix with minimal wiring but I don't want to mess up the arduinos that I'm using. I have an 11.1 volt lithium polymer battery with 6Ah that I want to power an Arduino UNO and an Arduino Micro. Any thoughts?

Sure, just use a Y cable and connect to both. The battery won't care.
