I'll take your word that the crimps were good and the screws and nuts are tight. What sort of motors did they have in their drivetrain? How much wire was removed from the loop in total?

My gut feeling is that if cutting out a few feet of wire made that much difference (you probably didn't cut out 12 feet or even 6 feet if they started with 6 feet), they are probably still just above the brownout threshold of 6.8 V. It is likely that they still have some other issues such as batteries with high internal resistance and that it is likely that their brownout problems will return.
