Hi,
On the web site specification it says :
5V input maximum -0.3 to 17.0V. Is this "input value" the battery input maximum and minimum ? Does the ultraborg have a regulator on it? ie what would happen if I connected a 9v battery ?

No - the UltraBorg does not have a 5V regulator
No - the UltraBorg does not have a 5V regulator, the voltage supplied to V+ and GND is passed directly to any fitted ultrasonic modules and servos!
If the "5V link" jumper is fitted and you connect a non-5V supply to V+ and GND you will probably damage your Raspberry Pi. With the jumper removed this connection only powers the servos and ultrasonics.
