Yesterday I made the first 3 test runs but without field weakening.
Had some problems with the pump which was not working at the beginning, so I was able to destroy the controller without circulating water. I measured the voltage at the pump and it was ok.
But after 1st run the pump was working. So maybe a loose connection? Or dust inside the cooling system which blocked the pump? I really don´t know!
So the first run I did a little bit slowly but reached 150 kph after 410m.
I calculated a top speed of 150-160kph before (less voltage, bigger tire).
Then I forgot to measure the max phase current
Ok, after I heard the pump working I decided to do another test run.
But I do not turn the throttle at full power from the beginning, maybe 4-5m far away from the starting point.
After the run the Garmin showed only 110kph and I was sure that will not fit the regular speed I feel!
I also measured 400A max phase current.
So I did another run (3rd) and turn the throttle direct on full open position.
But I did not get a spinning wheel as I had two or 3 weeks ago!
So after half of the distance I thing I reached top speed and after finish line it was only 138 kph.
The bat voltage reduced from 116,5V at the beginning to 109V after the 3rd run.
And I also measured only 414A phase current.
So there are two possibilities in my point of view.
The spinning wheel I got with 100V (4x6S Turnigy) which has 8AWG connection. The 4S lipo has only 10AWG.
So I don´t know if there is a bottle neck due to the cabeling?
Or the spinning wheel I got 2-3 weeks ago where the reason of the under ground!
I can start to make a test run again by 100V and measure the max current again by next week!
I will prepare a short movie clip by the next days!
