Is this I2SE gear clicking noise normal?

[sorka]

On a brand new I2SE with 1 mile on the odometer and 0.2 on the trip(from dealer setup).

I've been on many segway tours on I2 (although not an SE) and have never heard this clicking noise before. It's coming from both gear boxes on either side whenever there's a transition in torque from forward to backwards to forwards.

Video shows the noise:

Any chance this unit was shipped without gear fluid? It's a 2017 that was just unsealed from it's box last week. The dealer replaced the battery because the originals sat for 3 years in the sealed box so now I have new lithium ion units.
