as x-ray said, the 3.6 phone battery works fine plugged into the 'battery' pins on the side of the mobo. A kid from next door showed me how to remove the narrow, 2 pin plug on the end of the wires so I had two separate wires with teeny little metal clips. There's a teeny plastic clip you lift up on the plug end that frees the wires with their metal clips intact. They slid onto the pins on the Miggy mobo fine and I glued some velcro to the side of the battery so I could remove it and recharge it in a phone base when I needed to. Very easy. Thanks, x-ray, for the good idea.
