i wanted to know if the VEX power pack could last through the competion. if not, how do we endure the competition?
It will work fine for some robots and some robots will need several batteries to operate on. In fact you should have several batteries and chargers so that you can always have a battery fully charged to begin your match. How long the battery will last is determined from the load your robot puts on the battery. The load that is put on the battery from your robot will change from match to match – sometimes you may be in a “pushing match” with your opponent and be stalling some motors. When a motor is stalled, your battery will have a major drain on it reducing the run time of your robot.
