I've got 2 questions re: the second battery option for the Matrice.

1.  How does the GO app deal with the second battery?  Does the battery detail screen show 2 batteries (and their respective cell status) or does it show some sort of average of the two?  Does the % remaining show an average of the 2 batteries?

2.  Documentation says both batteries need to be the same type - so, I assume this means I can't use the 47D and 48D - both must be (2) 47's or (2) 48's?

About the battery info, if will show the informatioins of the one which was connected to the central board. You can use the 47 and 48 battery, TB47D and TB48D are the same type.
