I was actually thinking of the voltage before I read your post. I do have meters The voltage on the 12s batteries is 50.5 volts and being that the ESC and fan are 44 v. I was thinking maybe the voltage is too high. so at this moment I am discharging my lipos down closer to the 44 volts and then I will give it another try. also, my battery side total length of the wires is about 8 in and the same on the load side of the ESC., lol, I do not plan to terrorize anyone and will play with my toy in the most respectful way possible. :-) if I can ever get it to work. what is life? If you cannot have a little fun.. I very much appreciate the suggestions and help. I will continue on....
