Correct, this new ESC has always had the issue. I have updated the firmware, and have even updated it to no limit firmware to experiment there.
I had another one in the past, same model, which seemed to have died for no reason. On this old one, I had just got back from a normal ride, hard accelerations on hills and some slower cruising. Pulled back home, loop key disconnected it, and threw it on the charger. Come back next day and only one motor ran… everything I tried could not get connection to the dead side. CAN, USB and receiver plugged in yielded nothing.
Heres the thread (Dual FSESC6.6 Mini Half Working)
This new ESC that I have will always cut out if it draws more than that ~70A. On the medium settings, board performs perfectly normal, I can full throttle it, hard break, whatever really. Just went on a ~10Mile ride Wednesday all in medium no issues. If I did however kick it into high and try to drive on grass or even just trying to punch the acceleration, it would cut out within half a second.
Maybe reinstall VESC Tool is worth a shot… Ill update the thread with how it goes. Still really puzzling how it has all the symptoms of ABS current fault, yet ABS is set to 1000A.
