I couldn't hear a ticking noise over the starting and stopping of the 2 drills and 2 chips in our drivetrain.

Since this problem never occurs while using a 2004 battery I think we can rule out an electrical problem on the robot.

My guess- We were tethered at the time. Using the RC to power the OI. Could the reseting I was seeing the result of a loss of communication with the OI?
Yes, this is a possibility. More likely though is that your robot uses a high amount of current when up on blocks in the pit. Much more than it does on the floor. (Strange but possible) More likely is a combination of the loose connections on the battery and the backup not fully inserted in RC. When you checked the backup was it in place on the RC while the RC was running? If not, you may have had a discharged battery. Innovation First was checking backup battery via modem stream and informing teams of low backup battery condition, so if you were competing OK then your backup was good when you went onto the field.
