...and here is the short story. Sharp stones caused a flat tire. So I had to open up my KS18A (1200W 1360wh, no stock cooler fan but added afterwards), disconnect the battery connector and the motor connector, to repair the tube. Impossible, because the isolation of the motor power connector was molten together. It was necessary to cut off some isolation materials to get the connector apart. As you can see on the pictures, the 3 lines for power supply to the motor, sticked inside the connector housing. The data connector pins (or the pins for Hall sensor) are ok. The luck I had this blowout, otherwise I would not recognise this approaching problem early enough. I know that this relatively thin cables and connectors are a known weak point and that there’s a reason for, why Kingsong released a KS18A with built in cooling fan and stronger motor cables... But for those who maybe have the first generation of KS18A (new or used) and didn’t knew about the weak points, check your connectors regularly. ? I contacted my seller (AliExpress, yes I know eye-rolling) and he told me he will send me a spare connector for free... which is very nice but it’s not a safe solution to use again the same connector. So I gave my wheel to a good friend who is professionally repairing electronics. So he replaced this weak connector with highpower-connector which are also used for rc planes etc. Now my wheel is working fine again, it’s save and I was able to patch the tube without dismantling the motor. ?
