FAQs
Ouxi V8 Controller (48V 21A): Questions and answers
Will this controller fix error code 08 on my Ouxi V8?
Yes, error code 08 on Ouxi e-bikes often indicates a defect in the motor control unit (controller). Replacing it with this original part resolves electronic malfunctions and restores the bike's functionality.
Does this controller support my existing alarm system?
Yes, this controller is explicitly labeled as a "VB Controller Alarm". It has the necessary connections to control the anti-theft system of your Ouxi V8.
Can I also use the controller for 36V batteries?
No, this controller is permanently programmed for a DC48V system. The integrated undervoltage protection shuts off at approximately 39V to protect a 48V battery. Operation with 36V is therefore not possible.
