Here we check how long the DJi Mavic Pro battery will last when adding extra (360) cameras :
25:27 : Empty (799 grams in total)
17:42 : With 1 Samsung Gear 360 (932 grams in total)
13:03 : With 2 Samsung Gear 360 (1125 grams in total)
I ran into some issues with the screen recorder but you get the idea.
