What should my input voltage be?

Hi,
Ik was wondering what input voltage I should take, let’s take for example a 100KV motor and let’s say I want to let it turn at 4000RPM should I input 40V (40×100=4000) or should I just input 48V and let ODrive handle it?
Cheers

Just give it 48v and let ODrive handle it.

Okay thanks
