Lishui Controller Programming Work Info

Lishui controllers are widely used in e-bikes and can be programmed using official tools or open-source alternatives. Programming typically involves adjusting hardware parameters or flashing new firmware to modify performance characteristics like speed limits and current levels Endless Sphere DIY EV Forum Official Programming Methods Official programming is generally done using the Lishui Controller Programmer software and a dedicated USB-to-serial adapter. opensourceebikefirmware.bitbucket.io Software & Hardware Lishui Programmer : The official Program Downloader is used to upload firmware files provided by the manufacturer or tech teams.

Part 2: The Programming Ecosystem – Tools of the Trade

Unlike generic Chinese controllers (Kun Teng, BrainPower), Lishui does not officially release public programming software. The community has reverse-engineered the protocols. Here is what you need for Lishui controller programming: lishui controller programming

Lishui Port        USB-TTL Adapter
TX (Pin 3)    -->  RX
RX (Pin 2)    -->  TX
GND (Pin 4)   -->  GND

Step 3: Install Software & Drivers

• Install the CP2102/FTDI drivers.
• Run the Lishui Config Tool as Administrator.
• Set the COM port in Device Manager (usually COM3 or COM4).

1. Why Program a Lishui Controller?

Stock settings are a compromise. Programming allows you to: Lishui controllers are widely used in e-bikes and

• Communication Issues: Verify the serial communication parameters (baud rate, data bits, stop bits, parity).
• Command Errors: Check the command structure and checksum calculation.

• P08 – Speed limit (0-100%)
• P12 – Current limit (amps)
• P14 – Regeneration strength (0=off)
• P15 – Low voltage cut-off (volts)

Lishui controllers are typically "OEM-locked," meaning they are programmed at the factory for specific bike models and aren't as easily customizable as KT (Kunteng) controllers. However, you can modify them using specialized hardware, manufacturer tools, or community-developed open-source firmware. 🛠️ Programming Methods 1.
