Re: First ride in my cart
FWIW my Medalist is set up real similar to yours and the best it can do is 17 mph

Re: First ride in my cart
The logs for the most part look OK, but there are a few anomaly errors every time the pedal is pressed.
It may just be a timing thing with the SR Controllers since the Pedal micro-switch provides the KSI input to the Controller. Since You have a FN1 switch and the log showed the setting was on minimum, can You please post a picture of Your settings screen as well as the "Speed and Torque" curves? I just want to double check the curves are not demanding current right at the time the pedal closes and what the FN range looks like. |

You actually got Armature current above 290 amps, but there are so many runs and without knowing the conditions for each run it is hard to judge if the Controller and Motor were reacting appropriately. Some of the runs show around 60 amps during 100% throttle, that would be about right for level pavement cruising current consumption. I think You still have a stock Motor, so keeping the "throttle rate" low helps preventing the Motor for overheating since the Motor can use way more current (if allowed) during acceleration than it can convert to mechanical rotation. The battery voltage seems to holding up fine during high current demand, but You started the tests with a battery voltage of only 49.6v. |

Re: First ride in my cart
Agreed, The batteries look like they are holding up under load. The motor pull near 300 amps at marker 604 and the 49v pack fell to 45v. That's good.
