If you are planning on doing this on any kind of regular basis, however, you might want to consider a "deep cycle" battery rather than standard automotive battery.

Deep cycle batteries have a slightly different plate design so that they can be repeatedly discharged and recharged without damage.

Car batteries are designed for maximum current draw... short bursts of current to the starter motor and then recharged right away from the alternator.

You might find deep cycle batteries listed as RV or Marine batteries.

But if you're only doing it once... you should be fine. And if you don't discharge the car battery all the way, you should be better than fine.

Keep in mind, of course, that your "robot" batteries are SEALED lead acid batteries... they don't leak when you tip them over. Car batteries like to be kept upright... so you might not want to do too much bump climbing during the parade.
