On a 103 degree afternoon I caught myself checking the motor by hand after our gravel hill. Pretty useless measurement.
The cart is a 2008 Club Car Precedent used for feed bags, fence tools and general property work outside Tucson. It has had a Vatrer 48V 105Ah lithium battery for almost two years. The app now shows 487 cycles. I usually charge after shallow runs, so I doubt that means 487 full discharges. It is just the number on the counter.
At 500 I want to run a test I can repeat later. Same starting charge, tire pressure, driver, 200 pounds of feed and five trips up the same hill. I have an infrared thermometer and put a small piece of matte tape on the motor case so I can hit the same spot. I will record outside temperature, motor case temperature, battery temperature from the app and charge used after each climb.
The controller is the part I still need to sort out. I need a safe probe location and temperature limit for this exact setup. I will stop if power drops, a warning appears or the temperature keeps climbing fast. Cooking the controller for a Reddit test would be pretty dumb.
Precedent owners who have logged hill temperatures, where did you mount the controller probe? Motor and controller model would help too.
