It's acutally pretty easy to kill that battery. If you just powerup the bot with out ever establishing a link to the OI it will just sit and listen till it kills the battery or someone presses reset. I also noticed that the connector on the RC and battery are kinda cheesy. Perhaps it has come loose?
As for the battery 'pulseing' power, I would very carefully check the breakers. It sounds like there may be a short on either your RC circuit that is causing that breaker to trip. Did you hear any ticking noises? Perhaps the RC has an internal fault.
Before you toss a battery, eliminate all other possibiltys. Batterys not be cheap.

Yes, I checked the backup with a volt meter; it was charged, 7.3V I believe. They were only last years batteries so it's not a huge loss. We just wanted to keep the 2004 batteries on the chargers while we use the old ones in the pits. 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?
