@pfeerick: you could, quite easily and conceivably, fashion your own holder, or indeed use any holder you liked to hold a 3v battery to power the RTC.
To those not wishing to spend any money yet wanting the benefits of a RTC, I would strongly advise against soldering directly to a battery and directly to the board. Use an appropriate holder and connector.
Direct soldering could damage the battery, the board, and/or yourself.
Indeed it does... nice spot Ghost!
After some examination of datasheets (seems to be all the rage for this board... hunting through schematics and datasheets! lol), I have come to realise that the RTC voltage will be either 1.8v or 3.0v. Since it is using a coin cell or 2xAAA, it is most likely set to 3v. So, a CR2032 battery in a holder with suitable 2-pin JST holder it is! As 2xAAA would be plain overkill!
Not that my pine really needs it as it should have network access whenever it needs to sync the time, but never hurts to have a backup just in case...
