Warning: Incorrect programming can brick the controller, overheat MOSFETs, or cause battery damage. Proceed at your own risk.
Various GUI applications exist, often labeled generically (e.g., "Lishui Config Tool" or "E-Bike Controller Program"). These allow you to load a .bin configuration file or modify hex values directly.

If your Lishui has unpopulated 4-pin header (usually SWDIO, SWCLK, 3.3V, GND), you theoretically can reprogram the STM32 chip. But: lishui controller programming
Skip this unless you’re an embedded engineer with time to burn.
Lishui controller programming is legal for off-road use, private property, and racing. However: If your Lishui has unpopulated 4-pin header (usually
Fire Safety: Over-programming (e.g., 25A on a 12A-rated controller) overheats MOSFETs. When they fail, they often fail "shorted," sending full battery voltage to the motor—which leads to a runaway condition and potential thermal event. Always fuse your battery at 1.25x your programmed current limit.
Open your controller case. Look for a 4-pin header labeled: Skip this unless you’re an embedded engineer with
Some models use a 6-pin JST connector. If unlabeled, trace the pins back to the MCU. Pins PB13 (SWCLK) and PB14 (SWDIO) are common on STM32F103 chips.
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.
