This got me thinking about IF the electric motor battery pack was
still installed and the info I found was inconclusive.

There WAS some kind of battery installed to power the lights and radio but that would be some kind of "house" battery specifically designed to survive in space. Wiki

Personally, I do NOT think the battery pack was installed NOR any accessories related to it (ie: cooling system and cables). The drive motor was probably removed, as well. Why? (1) for weight savings and (2) because the propulsion batteries may not have survived in space.
So I'm going to add that I BELIEVE that 0% of cars "driving" (traveling) in outer space are battery powered...
PS: my belief does
not include terra-based vehicles such as the lunar or Mars rovers...
