Battery issues damaged EPS controller CU50-73 with PB82-63 & PB82-64 Mosfet boards inside. Problem traced to faulty Hybrid IC EPSC 624942 on PCB board PB82-63. Does anyone know if you can buy the Hybrid IC replacement or the availability of a working second hand CU50-73 Module(P/N 25200-03460). The replacement module may now be CU51-46 (P/N 24200-52001). I have found what appears to be a suitable replacement from Guangzhou Dawn Electric Vehicle Co. Ltd. via AliExpress designated EPS-4850, (48V 50A, 300-600W), they claim it is NYK EPS controller compatible, has anyone used one of these, is it a direct replacement? I am located in Adelaide South Australia.
