Ok, that confirms my suspicion... I figured that the way we wired the LED's made them overly sensitive to what turns out to be a normal voltage dip. We never did see any drive issues or latency or cRio resetting so we assumed everything as fine but it was still a bit unnerving to see the LEDs dim so much at times. It was consistent across multiple batteries so we figured it wasn't a bad battery as was our initial thought.

Thanks for the replies and good luck.
