If you run a brushless motor unloaded it can over rev... I would not do that...
Unloaded amp draw is not very useful. Put it in the truck and try running it under alot of load.
Are you sure that it is 20kg? 2.2lbs per kg... over 40lbs? If so then you need a much bigger esc, or a 20s setup. Is the chassis steel?
150 amps at 39v is only 7.8hp, and that is before any losses are considered. That is not enough to run a 40lb vehicle, IMO. You may on the edge with that setup, the motor should be good for 10hp or so, but that esc is a bit undersized.
