How dead do our batteries get? I'm sure to be honest. The Coding Team has figured out a way to have our laptop play a sound "Low Power" sound when our battery voltage gets too low and then we change our battery. It seems to be working so I haven't looked into the voltage that they've picked.

Our robot for this year's game is not a huge current hog. We have 14 motors yes, but the Gripper & Pusher motors are off literally 95% of the time, the three arm motors and the lift motor are nearly perfectly counter balanced and the three wheels are never scrubbing because they are always pointed in the direction of travel with respect to the ground (thanks to the awesome programming of Paul, Michael, & Owen -- you guys are rock stars!). The motors that get hottest, believe it or not, are the three swerve motors.

Don't know if that answers your question, but that's all I've got...
