OK did a quick comparison between inspire 1 with the T48 vs the T47 vs a PV+. here are the results: Steady hover, ~6 ft elevation, temperature ~38 C, sunny. PV+ From 95% to 28%: 14:12 T47 From 99% to 28%: 12:43 T48 From 99% to 28%: 15:34 T48 seems to give a 23% flight time increase with 30% more capacity. Not very scientific but maybe gives people a ballpark idea. PS: the phantom moved around a lot more and may ave burned more gas constantly correcting for the perceived PS location whereas the I1 held rock steady. PPS: I did take picture and movies, played around with settings in all cases. I did not move the gimbal during each test.. PPS: Te PV+ takes longer to satellite lock and you lose more battery before you can take off. IMU etc draws of a smaller battery and takes a relative larger chunk.
