Board randomly powering off after battery upgrade

After I had a third-party install of a 10S5P battery in my GT, it unfortunately came back with a defect - after a few kilometers it automatically turns off. If I wait a couple of minutes, I am able to power it on again and drive a little, then it switches off again.

It turns off even faster when I go full throttle in GT mode.

After some research I found out that after a battery upgrade it may happrn that the temperature sensor of the BMS was placed incorrectly so it might be too close to the ESC, which is why the board may think it is overheating.

Now I am trying to check how the temperature sensor is placed and if that is the problem, but I just couldn't find any information on where exactly to find the sensor.

Can anyone help me out? Where can I find the BMS temperature sensor?

 

The temp wire is a black wire that looks like the end was melted into a ball. It’s not that long 6”.
