Progress to date:

• 1 controlled led using Blynk
  2 controlled a single servo

so now I am moving on to control 4 servos, as with another post I want to use my WiPy for a Bob the Biped robot.

I have looked at the expansion board schematics and if I understand them correctly I can power the expansion board from a USB rechargeable battery and then use Vin on the expansion board to power all 4 servos.

Is this going to be Ok?

I am hoping to print the robot this weekend and then start on the software next week

I'm wondering the same thing - can I source ~5V off the Vin pin?

How did this work out for you?

That should be possible. The power switch current limit is set at 1.2A
