The motor that is not powered will be a parasitic drag on the motor that is driving. The powered motor will be spinning the other, the dead motor will become a generator. It takes additonal power to turn the unpowered motor. How much actual battery power you save is questionable. If you could mechanically disconnect the dead motor from the working motor, the battery savings could be real. But then, if you just keep a couple of spare batteries on chargers between matches, you should have plenty of power. We ran 4 CIMS with the kit gearboxes and the door motor for our lift last year, and had plenty of battery power at two regionals and nationals. The only time that we had to hussle to keep batteries charged was during eliminations matches where you run back to back matches. If you take care of your previous years' batteries, you should have enough by now that you don't have to worry about having enough charged between matches.
