Kraton 8s - 30t/47t
Was doing some smooth accel, medium/fast speed passes on a large parking lot yesterday. First pair of batteries went great. (I have 4x GensBass 11Ah, 100C, QS8 for everything)
10min into second pack I let off the throttle, it rolled to a stop and that was it. No throttle response. Thinking the end was nigh, I ran to it and quickly disconnected the batteries. All electrical components looked fine. (No melting, smoldering). Tested batteries I was using and all 8 cells still >4v. Both batteries had a temp around 70F. QS8 connectors were similar. Motor and ESC both less than 100F. (All tested with temp gun)
Got it home on the bench. Tried both pairs of batteries with same results. The audible beeps for cell count/arming are so soft I can hardly hear.
No throttle response from dead stop - sometimes it'll jerk awake and then throttle works normally. Steering and motor fans work fine. ESC LED double beep indicates Start Fail.
Then I tried without the sensor cable and all was well - motor starts right up every time with some occasional cogging. However, beeps from ESC/Motor are still super quiet.
ESC data log from session incident occurred:
Max amps: 200
Max ESC temp: 99F
Max motor temp: 117F
Max voltage 38.2v(!). A blip right near the end.
Isn't there unofficial consensus that the XLX2 is suited for speed running? Seems like my driving style so far is a low-key version of that. (I haven't gotten this rig airborne yet).
