In the A4WD1 rover kit they provide a Sabertooth 2x10 Motor Controller that are used with the 12V GHM motors available from the site.
However, It so happens that I have a Sabertooth 2x25 controller available to me.
I was wondering if there might be any issues or problems with using a motor controller with a current rating much above what I actually need. And whether or not, it would be more wise just to use the 2x10 motor controller.
