Even better of an idea, though also dangerous, would be to place a verry powerful NiB magnet on the battery and the robot. If powerful enough, it will restrict the axes of movement but allow the battery to move enough so it doesn't get destroyed by the vibrations. On our battery restraint, even if it was ope, it would have protected the battery from the highest g-forces possibly (falling from the third rung)

Reusable zip ties work really well on the battery connectors. If you spend a lot of time making a fancy battery box, the team will take it off when the robot weighs too much, so simple and light solutions are always good. However, a single zip tie is NOT STRONG ENOUGH to restrain a battery. If the robot is hit hard enough (like falling off the tower), the battery will break the zip tie, and could hit something important (like the power distribution board).
To add to the list-
Always make sure you maintain your batteries well.
Do not leave a bunch of batteries in a place where they will go from <32*F to >80*F.
Make sure that all of your team knows never to lift the batteries by the connector. Someday, the terminals will be ripped right off of the battery.
Also, don't ever charge a battery that you suspect may be damaged/dropped. The battery will expand, get stuck in your charger cart, and leak stinky acid all over the place.
