I'd think you could write a sh script and use curl (you can install curl). Not sure if you could find kcbatt anywhere since the link here is dead: http://talk.maemo.org/showthread.php?p=155915 but that could get you the battery level. Not sure if battery-status can be run without activating the applet. I'd write you the script if you figured out how to get those 2 levels from the command line.
