to 5V (Only use if powering the controller brain logic directly from the USB; otherwise, power the controller normally and leave 5V disconnected). Step 2: Driver Installation
Would you like a shorter version or one focused on a specific use case (e.g., cargo bikes, scooters)?
By unchecking "Keep Current Settings" in official Lishui tools, you can sometimes manually set new maximum current and low-voltage cutoff values. 3.

Lishui controllers (LS), manufactured by the Nanjing Lishui Electronics Research Institute , are widely used in e-bikes for their smooth Field-Oriented Control (FOC) performance. Programming these units allows riders to fine-tune torque delivery, adjust current limits, and even install custom open-source firmware.
Programming a Lishui controller is a rewarding way to make your e-bike feel truly customized. By taking it slow and backing up your settings, you can safely explore the limits of your machine.
Fix: Reverse the “Hall Angle” parameter (60° ↔ 120°) or swap any two phase wires. to 5V (Only use if powering the controller
Lishui Controller Programming: A Comprehensive Guide to Customizing Your eBike
To program a Lishui controller, you need specific tools to bridge your computer and the controller. Hardware Needed
Lishui provides official software and tools for updating and configuring their controllers. The primary interface is the . The programming hardware involves a specific Lishui USB to Controller Programming Cable or the FPS2 USB stick to connect the controller to a computer. The official firmware files are distributed in the .lsh file format . Users can download the official Lishui-Tool and initiate the programming process by selecting the appropriate COM port for the USB adapter, loading the desired .lsh file, and clicking "Program". However, some users report that generic programs struggle to read the proprietary Lishui USB cable, often requiring the official firmware updater software. ST-Link V2 Internal PCB Pins Complete open-source firmware
Below is a comprehensive guide to Lishui controller programming, covering hardware identification, software tools, parameter configuration, and advanced tuning.
For those seeking complete control, the open-source path is the ultimate destination. By replacing the factory firmware entirely, you can fundamentally change how your controller operates. While risky, the rewards are immense.
Always click "Read" or "Backup" first to save your stock firmware file.
The software landscape for Lishui controllers can be fragmented. There is no single official "Lishui Suite" distributed publicly by the manufacturer; instead, the community relies on leaked OEM software or open-source projects.
For many modifications, the single most critical step is . You must disable the Read-Out Protection (ROP) bit before you can flash any new firmware. Typically, this is done with a single click in the Java configuration tool. Do not forget this step , and remember that it irreversibly deletes the original factory firmware, so a backup is impossible.
