Do you see the data such as "Charge cycles"? If so, then maybe you already have the current firmware. Sometimes when you update the Phantom, it goes ahead and updates the battery.
I do see detailed battery information, including charge cycles. Still, why might that be indicator and not definitely an indicator of firmware version?
