Guys,

Thanks for the explanations. I thought the op amp that Rob talked about was just for low power dropout set to around 7.6V or so. I checked the output of my op amp and it drives high (thus signaling the processor) at 10.51V or less. At the same time the player resets and then shows the low battery icon. I will now monitor my battery voltage at the sled and see if it is in fact 10.51V I still wish the voltage threshold was less, I may (at my own risk) change the reference voltage divider so the threshold is closer to 10.0V. I'm sure if I had a big new battery this problem would not be as bad though. The player seems to run happily down to less than 7.0V so I would not think the op amp would have to be 10.51V.

Thanks for eveyone's help.
