Query on flight times with different li-po batts
Firstly I'm a noob so if any of my queries sound really silly, pls pardon me.
Assuming I hv a 2200mah 25c 11.1v li-po batt pack that means:
the max output for this batt would be 2.2A X 25=55A and the max time period in which the max output of 55A could be sustained would be 2.4mins.
First of all: is the above calculation correct?
Hence if I am using a motor eg OBL 29/37-10H with max rpm of 3700rpm with a max efficiency of of 4-20A and max surge of 30A/60s, would my following calculation of flight time be correct?
Since I am only a beginner just learning how to hover, my throttle curve is set at 50% for take off i.e.3700/2=1850rpm. Now I know for a fact that the power consumption for the motor is between 4A and 30A, which means that at 1850rpm, the power required would be 17A.
Before I proceed further: is the above calculation correct?
Therefore combining the two equations from the batt pack and motor (Notwithstanding other variables eg additional load like fuselage and weight of battery etc), I would calculate my flight times to be:
If 55A = 2.4mins then at 17A = 55/17 X 2.4 = approx 7mins but since we do NOT fly until the batt discharges completely, we would only fly 80% of the max 7mins which would come to approx 5.6mins.
Would this form of calculation be accurate?
