Once again Hong Nor (Jammin) CRT.5 brushless conversion

[tomik]

Some test drives with datalogger today :). Here you go...

Setup: HN CRT.5, CC SW, CC BEC, KD36-60-07L 3500kV, 16T pinion.

Test #1 with 1800mAh 20C 3S pack from HobbyCity (Lloong max).
Max amps: 91,19A
Watts: 699W
Voltage(t) and Amps(t) -chart from test #1

Test #2 with 6000mAh (100Amps) 2S pack.
Max amps: 115,18A
Watts: 706W
Voltage(t) and Amps(t) -chart from test #2


Then after a little while of running with the 2S pack there was a ~15secs break and then the car died!
- SW keeps blinking all three lights
- CC BEC has no leds whatsoever
- Steering servo doesn't work

To me it seems like CC BEC is dead, but how can it be? It should be able to handle from 4,8V to 25V. Can anyone tell me what could have gone wrong?

EDIT: I measured the output voltage, which is 2,14V. It should be 6,1V :(.
