Jack,
While that is true, your robot would not be able to move, as there is no other legal method of converting the energy stored in the battery to work that results in the mini bot going up the pole. Update 1 disallowed stored energy within any other part of the mini bot being used to propel the mini bot up the pole.
Although, It could be a good move for teams without a minibot, or minibot deployment capability to carry the battery of a teammate for the coopertition points.
In any case, you are right, the only part required to be on the mini bot is the battery. But then again the rules don't require the robots to be mobile either
