I think it depends on how much you want to optimize things. Bear in mind
that the later ET PM motors didn't (couldn't) have field weakening.
If memory serves, and it might not as it's been many years, Mark Hanson
ran
an E15 with full field and 48 volts from his own homebrew PWM armature
controller. I think he got about the same top speed as on 36 volts with
the factory field weakening. He had a second controller to drop the 48
volts to 36 volts for the attachments. If he's still on the list, maybe
he'll chime in with comments and corrections.
