Yesterday here was the numbers 4200mah total, I used 1002mah in 15:00 mins of flight that's using 66.8mah per min 66.8 x 40 mins is 2672mah of 4200 = 1528/2= 764mah left in each pack after 4-10 min flights. This is not good!
Today Here are the numbers. 4200mah total, I used 810mah in 18:00 mins of flight that's using 45.0mah per min 45.0 x 40 mins is 1800mah of 4200 = 2400/2 = 1200mah left in each pack after 4-10 flights. This is great! 1200mah is over 1/2 the capacity (1050mah) os the 2100mah packs.
If id did the math right, I am safe to fly 4-10 flights with Zero risk of battery failure. Basically each 10 min flight cost both my packs a total of 450mah. Also I just ordered 2 more packs in case I want to put in round robin flights all day long.
So did I do it right guys?
Sounds like you did the math right. One lesson learned from my mentor, John: always check the voltage in the packs after EVERY FLIGHT. Never assume...always verify. Odds seem to be much less with lipos and LIFE batteries but they can still go bad...so verify before each flight. I know this will not "guarantee" that the pack will not fail, but it "could" help identify an issue before you get in the air.
