> After installing this controller, single‑drive mode will no longer be available; only dual‑drive operation is supported.
> The original S/D toggle button still functions, however the S (single‑drive) setting will run under dual‑drive output. Performance under S mode is comparable to the stock 55A controller. When selecting D (dual‑drive) mode, you will experience improved overall speed and performance.
This 70A controller delivers significantly higher torque. Frequent hill‑climbing and overloading will create heavy‑load operating conditions for your scooter.
Under heavy load, the motor cannot reach high rotational speed. If you continuously use Race Mode, the controller will keep supplying high current to generate extra torque to drive the motor. Sustained heavy‑load operation puts extreme stress on motor wiring, which may result in motor burnout. Extended riding under these conditions is not recommended.
If you aim to reach speeds of 110‑150 km/h without component failure, an upgraded higher‑power motor together with a higher‑capacity battery will be required.
Disclaimer: Please be advised that damage caused by modification, heavy‑load misuse, improper matching of motor‑battery‑controller setup is not covered under our product warranty.
⚠️Please note: This controller is only compatible with the X7B display. Replacement is not supported if you have a different display.
