does higher KV equal more power?

A motor with a higher KV wants to spin faster, so with the same prop it might put out more power to the prop. It can also draw a lot more power from the battery but put out less power to the prop because it can be overloaded with the same prop as a lower kv motor.

They should provide about 15 volts altogether (3.7 * 4 = 14.8), and each battery is rated for 35 amps so they should be able to power my motor which draws 25 amps at full load. Alternatively, I can use a different model of the motor which draws less amps but more voltage.

Do electric cars lose some horsepower as the battery drain? If

That would be true if the inverter limited the total delivered power to the lowest possible battery voltage at all charge levels. Which they typically don''t (except for that Leaf owner below). So, the answer is Maybe. As battery voltage drops with state of charge, the maximum available horsepower to the motor may be reduced accordingly.

Why do higher voltage batteries need lower KV motors?

A 4S (15V to make math easy) battery will turn a 2000kV motor at 30,000RPM (with no load, inefficiencies, etc) a 6S (20V) battery will need a 1500kV motor to achieve the same RPM. In theory, the result is the same amount of power (watts) required to achieve the same RPM/power output/etc. A 4S 2000kV motor will draw say 20 amps, or 300 watts.

What determines how much power the motor ''draws''?

So, whenever you connect your DC motor to a 9V battery, it won''t draw infinite current, and won''t instantly jump to 6000RPM speed. It will however accelerate, and momentarily draw a large current while doing so. All motors are flywheels. When first connected to a DC power supply, the motor speed increases, and kinetic energy is stored in its rotor.
