You would need to know how the PDS controller is configured. The EZGO PDS system includes regenerative braking which is referred to as a motor brake. To my way of thinking regen will run hotter than no-regen. The controller is configurable for more or less regen. To configure it for high speed will be less regen so a cooler motor should result. Being in Florida where it is essentially flat regen is of no value because I don't coast very long, however in a hilly area the regen may help and you may not do as well with the high speed setup due to less torque needed for climbing. Anyway I'm also a new cart owner and I selected the EZGO because I can simply set up the controller myself, not so much with club car where the controller can only be set up by a dealer. Anyway EZGO calls it changing the chip, but it looks like a jumper that changes resistance. Never forget that research is 3 sources of info, this is just one! I learn more when I listen, so let's hear it. rj
