original product made in Japan. If your car's battery is fine but only the controller is damaged, you can contact me. I have one controller in completely good condition, you can check it and then buy it, no problem. It was in my own car, I installed a new battery in the car! I sold the battery cells separately and kept the controller to sell it separately, that is why I posted this. If you need it, please contact me, the address will be given, you can come and check it!
