Rover v2 with xbee problem

Hi
I recently purchased a dfrobotshop rover v2.0 with 2 xbee shields and the usb adapter. It seems that the two xbees are able to communicate although I could optimise that however I have a strange problem. I have uploaded the wsda sketch appropriate for the rover without making any changes. I use a Mac with Mountain Lion and CoolTerm to send the commands. I can send two commands but on the third it seems the rover simply switches off. I have a Lipo for power and I obviously use the battery for powering up the motors and the arduino. Has anyone got an idea why the whole board switches off and there is no power?
Regards
DT
