Hi small league,<br><br>I'm Zach from University of Rochester Robotics. For our batteries and charger, we found a set of 5 batteries that each take an hour to charge. The charger only charges one battery at a time, so charging takes a total of five hours. In your experience in actual rounds, do you need a total charging time shorter than 5 hours? How much shorter? We calculated that one battery charge would last the robot 52 minutes, so that is almost 3 rounds. We will be trying to go to the US open this year, so there may not be as many rounds as in the world tournament. <br>
<br>If any one wants ideas for batteries and a charger, here's the batteries we are using:<br><a href="http://www.all-battery.com/148volt-4000mah20cli-polylipo4cellsbatterypack.aspx" target="_blank">http://www.all-battery.com/148volt-4000mah20cli-polylipo4cellsbatterypack.aspx</a><br>
