So I was looking at this motor:

KD A22-20L:

Kv: 1000rpm/V

Battery: 2~3S

Current: 6~21A

Max (A): 25

Max voltage (V): 11

And I was hoping to pair it with this battery:

FlightPower LiPo EONX Lite 2S 7.4V 2500mAh 25C

So on to my question: what is the range of voltage that can power the motor? The specs for the motor says that the max voltage is 11 V so that's the ceiling. The battery gives out 7.4 V so I was wondering if this is enough to start the motor? What's the minimum voltage required to start it? And finally, what's the best voltage?
