WHAT: 12-volt rechargeable battery
WHY: The batteries we have constantly need to be charged, because if the battery is not fully charged, the robot does not move the way that we expect. As the power decreases, the motors and the reaction time of the robot are slower. The chargers that we use are back from when we started the team, and they are not as strong and efficient as they used to be.
