150amps hobbywing esc in fire in my house!!!

Bad news....I broken my hw 150 and I do not know why....
Well I'm testing my new drift tires for 1/8 buggy, My hw was on 6s start mode 2 and tming 22 deg, I used it many times with this setting, at the end of the first battery I waited the motor to cool down esc was cold all the time, I connected the second battery, switched on the esc, I heard first bip from motor, second bip from motor, insted of the third bip I heard a puff from esc, like a burst, and then I saw white smoke, finish, end of the story, esc is gone, well now I start to get a little upset..this was completely unexpected and all the parameters were fine, I was not even using the throttle, jst put on the switch...anyone has a feedback of repaired esc directly from hw?
thx
