Is there a good way to calculate flight times with the new bigger batteries that are coming out? I'm flying a Cinestar 8HL with a MOVI 5 and a Canon T3i or Canon 5D for payload. I'm currently using 6S 10,000mAh and getting around 10 minutes. I was told if I went to a 16,000 mAh I would only get about 1 minute longer because of the addition of weight. I just saw a 22,000 mAh battery. What type of flight time could I get from that? It weighs 5.4lbs. 16,000mAh doesn't seem to be worth the extra weight for only one additional minute of flight time, how much more would a 22,000 give me? Thanks!
