4. When connected to the power I have check all connections still servos wont move.
A. Double check that you upload the code to the Arduino, and when connected to the power you don't see servos move a little
it means that there is no code running in the Arduino.
When the power is connected if you dont see any light on the Arduino that means the battery does not have any power.
