RE: School me on choosing the right Lipo plz
amadio1, here's a kinda quick rundown on how to choose. Let's say the motor/prop setup you choose will run around 25 amps constant, 30 amps burst (10-15 seconds or so), and your motor is designed to run 3S, or 11.1 volts. For a 1 kilo plane, you probably want a battery in the 1500-2200ma range, 3S. Each cell is 3.7 volts, so a 3s, or 3 cell = 11.1 volt.
With me so far? Now, the discharge rating, 20C, 30C, etc. A 10C battery means 10 times discharge rate, 20C- 20 times discharge rate, etc. With that in mind, a 2200ma battery (1000ma= 1 amp, 2200ma = 2.2 amps) at 10C can safely discharge 22 amps. A 2200ma 20C battery can safely discharge at 44 amps, 30C at 66 amps, ok?
So, a 25 amp draw from your motor/prop combo would be too much for a 2200ma 10C, a 20C would be fine, a 30C would be more than neccessary.
I hope this clears it up a little.
