Looks like the average flight time with 4 x 22000 mAh Batteries is 24 minutes…
Current[A] = Capacity[Ah] / time[hrs]
So 44000 mAH = 44 Ah
24 minutes converted to hrs : (24/60)[min] / 60[min/hr] = 0.4
Current = 44Ah/0.4hrs = 110 A
Average Amps in a flight is 110 A
Run_time(min) = Capacity(Ah) / Current(A) x 60min/hr
Capacity: 44 Ah
Current: 110A
Run_time = 44/110 x 60 = 24 min.
Theoretical run time with my 4 x 22000 mAh (9.96 kg) + 4 x 16000 mAh (7.72 kg) = 76 Ah
Current 110A
Run_time= 76/110 x 60 = 41 minutes
Run_time with 8 x 22000 mAh Batteries = 88/110x60 = 48 minutes
Hope this helps…
