To check the firmware version of the battery, you need to check the txt file that gets written to the sd card during upgrade. Then after the first battery gets upgraded (during your main upgrade of the air craft), you will power down, put in your next battery, and repeat the upgrade process. This time it will be faster, as only the battery will need upgrading. When complete, check the txt file again for confirmation.
To reset the home location, there is a teardrop icon on the left with the letter H inside it. When flying, if you press it, it will expand out with two options. One is to reset home to the current aircraft position, the other to the current position of your phone/tablet.
