Depends. Definitely v-Mount Battery (e.g. 95wh) for long runtime and reliability. But these can be pretty expensive. Adding a beefy Powerbank with USB C ist probably most economic and will still give you long battery life
In my menu under record for some reason the option to change sample rate and bit depth is not there? Wonder if I need to update the firmware or something, any idea whats going on? I have looked through all menus and can't change sample rate or bit depth unless I am using it as an audio interface for cubase - then I can change it. Just can't figure out a way to change sample rate and bit depth settings in stand alone.
Sounds like you're in Basic Mode. Go to Menu -> System -> Mode -> select Advanced or Custom to access the sampling rate/bit depth settings. This video doesn't cover the different mode options.
