I kept my battery pack as the motors are steppers and not really controlled by voltage but frequency. I did want to get rid of the extra cable though. I shortened the battery pack cable and Velcro'ed the controller to the pack. It is nice to have the strap to hang on the mounts altitude adjustment knob. The white cable is an ST4 guide port. These D batteries have lasted at least 6 months so far and that is with autoguiding.
