No I was just looking for the size. I was wondering why they didn't just use the Mavic battery as it lasts so much longer, but now I see how different the sizes are.
Each battery for every aircraft is designed in the margin between capacity and weight which adds up to flight time. You have too much battery and the dense things start to weigh you down and decrease flight time. Usually they choose the peak for each one, but also performance comes into it a bit so they might sacrifice some flight time for stability, power, or control and such...
Drone racing is really where the batteries start to get interesting and become keys to the kingdom
