Batteries

But its definitely possible to have the robot operate at dangerously low voltages, so it might be relevant to test the battery down to low voltages.

Do you typically run a fresh fully charged battery at the beginning of each match or is it possible the batteries had been used in one or more matches previously?

Our team rule is one match per battery per day. We put a freshly topped off battery in the bot at the start of every match and don't use it again that day if we can avoid it.
