Power Jetson Xavier NX

Hello! I have Jetson Xavier NX and I want to use it with my robot. I also have powerbank (10000 mah, 5V, 2A) and lipo battery (5100 mah, 3S, 11.1 V 20C). Is it possible to power jetson via these batteries?

The powe supply range to devkit is 9v ~ 20v. Yours looks fine to devkit. The real power consumption depends on your use case. So you can try your power supply and running your use case to see if that is good enough.

But I also power motors via this lipo battery (2x3A). Can this damage Jetson?

Not sure about that of motors.
