"The inertia of the mass that the sled is moving would cause it to continue if the sled stopped suddenly, such as by the operator releasing both move and direction buttons at once, especially due to the lightweight nature of the sled itself and the battery life being severely limited."

What does this mean? Does the mass carry the sled along, or does the sled stop while the cargo tries to keep going? Does everything slow at 0.1G? If the sled could generate more thrust, would it try to slow at the highest Gs it can achieve? (While the 0.1G is a good safety limit, not running someone down seems like a good place to override the safeties.)

Does the mover have any sensors, such as anti-collision? Ability to transmit video or other sensor data to a central location, wireless controller, HUD, or Augmented Reality device?

Wireless control seems like a natural, although an umbilical backup is nice.

Good write-up.
