(This is part of a multi-part series on building a FPV mini 220mm quadcopter)
You need batteries to fly a quadcopter. The battery we selected will be used to power the receiver, flight controller, the OSD, FPV video camera/transmitter and to power the four motors that spin the propellers and give the quadcopter the lift it needs. As you can see, the battery is very important and also adds the most weight per single item. We've selected the Turnigy nano-tech 1500mah 3S 35~70C Lipo Pack to power our copter.
