I would recommend replacing the [http://www.ifixit.com/iPod-Parts/iPod-4G-Photo-Replacement-Battery/IF193-016|battery] as well as the logic board. If the problem was merely the battery, you would still be able to power the iPod while plugged into the wall. Since the logic board controls the functionality of the iPod, you need to replace that to get up and running. Replacing the battery is a relatively inexpensive thing to do while you are replacing the logic board. If the battery inside is the original factory battery, chances are it is not in that great of shape.
