There is not a supported list of battery packs for the Galileo board, but here’s this thread that you might find useful, https://communities.intel.com/message/257972#257972. It is recommendable to use the provided power supply to power the Galileo board. But if you decide to use a battery, make sure that USB cable is not connected to the board when the battery discharges. Powering the board with the USB cable can damage the board due to insufficient power (this also applies when the standard power supply is used).
