I can't speak for the NXT, but teams using the RCX had this problem too. There is an easy way to deal with it--the rotation sensor. Use that instead of a timer, if you aren't already, and the only thing that'll happen is it'll take a little longer to get to the target.

I don't know how you'd monitor the voltage. There ought to be a battery indicator that'll help, but I don't kow how much or where.
