While I wait for parts of my quadcopter to turn up I have been looking at its power source and need some help with the batteries.
The motors, EMAX MT2213, can run with 3-4S battery packs. Playing with the calculator on eCalc.ch I am not sure what to go for. As it stands using a 3S pack would give me 6 mins flight and 11 hover. But if I add another battery I would get an increase in flight time (practically double) but to hover the throttle is an estimated 71%. Worse if I go to 4S as the current in flight goes over the rated Max of the motors.
I admit I am having to make assumptions about the craft (weight being one of them but calculated from the data I can find about the parts) and it is possible I am using the calculator all wrong. It has left me confused as to what to do. Basically I would like about 15 mins flight time overall.
Can I call on the more experienced guys to point me in the right direction?
