Avan,

Consider using your cRio, a couple spikes, and perhaps some 100 watt lightbulbs to create your own battery tester. If you draw down the power quickly enough, the power consumption of the cRio and spikes will be fairly inconsequential.

That would be a very neat project to consider. Perhaps you could do it and release the source code etc. Remember, the voltage is already recorded and sent to the driver station, so the capability to measure voltage and map it is already there!
