First of all, the motor will take just about any battery pack you wish to feed it through the ESC. The difference being the voltage applied for different cell configurations. The KV rating of a motor will tell you what it will do with various voltages. That is RPM/ Volt. So, if it's a 1000 KV motor, then a 6.6 volt battery will give you a free running 6.6 X 1000 or 6,600 RPM. If it's a 3000 KV, then you get 6.6 X 3000 or 19,800 RPM maximum with that particular battery. There is a limit so check with the manufacturer of the motor. For instance, a motor may say maximum of 4 cells LiPo (14.8 volts) or 6 cells NiCd/NiMh or 7.2 volts NiCd (more likely more cells but that's just an example).

The electric components of any E powered RC aircraft are the receiver (all have that), the battery, the ESC or Electronic Speed Control, and the motor. Of course the prop comes in there but that's not an electric component.

Some ESC's have BEC's or Battery Elimination Circuitry which is used to power up the receiver via the throttle channel. It acts as both a throttle for the ESC and the power for the receiver and servos.. and is limited in available power so check with yours to see if it will handle the servos you are going to use.
