If you get ~12 minutes of runtime with 3200mAh cells at 6s, that's an average current of 16A, and an average power of 355w. A bit higher power needed than I would expect, but whatever.
That's about the average power usage of all the guys I race with. I don't think anyone ever does a proper race with less than 300w average draw, some guys have the odd race with 400w+ draw.
Just an update, I did drop the cut off to 3.1/cell, and it did seem to help, but the motor still didn't have enough pop after about 5 or 6 mins. I went ahead and swapped in the tekin 1350 and it definitely cured my problems, I ran past 12 mins and it still had plenty of torque, less than at the 5 min mark, but definitely raceable unlike the xcelorin. I am guessing that the extra rotor length with the tekin is helping. I stopped shortly after 12mins but my pack still didn't dump so I am all good for racing 10min mains. The pack did however come off alot warmer than I am use to with my neu and zippy packs. So as long as my slipper clutch on my tekin rotor doesn't kick in, I should be all good. Thanks for the help to all the guys how made suggestions.
