Car Battery for post-season bot

[Al Skierkiewicz]

Eric,
If you correctly size the motor to wheel reduction the current in the motors will be low. The reason we have been suggesting a larger battery is the distance/time that it will take to get around the track. The best designs in our competition will get 3-4 matches from a single battery but there is rarely continuous current draw. With a larger battery, you should be able to run for a much longer and continuous period without worrying about the battery becoming discharged.
If the goal is to get someone around the track then a simple design should work fine. If the goal is to beat other teams around the track then that will require a little more design time and some better engineering.
