If I may, I believe it would be more appropriate to be more specific about the stats. For instance:
Repair Station
"A large station dedicated to supplying crewmen with materials to perform mid-battle repairs to damaged modules. Cannot be used to repair armor or restore destroyed modules."
Cost: 5,000
Size: 2x2 meters
Power Use: 1/activation
Power Capacity: 2
Ability Cooldown: 20 seconds
Ability Uses: 5/activation
Repair Speed: 100/use
Weight: 1.0 tonnes
Hit Points: 4,000
Crew Speed: 50%
How's this look? For the price, I did kinda low-ball it over the fact that it wouldn't be all that effective in terms of defense, more or less to keep modules that have been exposed running.
