Batteries have a very "quiet" supply voltage; there is no mains hum or switching spikes as you would find in a lot of DC converters so be prepared to be disappointed should you use one. Also, a lot of DC converters are a bit flaky on low loads and can rise significantly above their "so-called" output voltage.
