I am trying to find the electrical requirements for the Nikon SB 900 ext battery port:

What are the minimum and maximum input voltages at the port?

I would like to use a rechargeable Lipo battery pack (from a hobby / RC store)

You need a power supply, not just a battery. The voltage is in the ballpark of 325 volts, to directly charge the flash capacitor.

Instead, you definitely need a SB-900 power pack, like these:
