Goal: Go from 25km/h to 35-45km/h.
Method: Find the hex value 0x19 (25 decimal) in the firmware. Replace with 0x32 (50km/h). Re-flash.
Risk: Motor may overspeed beyond its mechanical limits (bearing failure).
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:
If you’ve ever opened up an electric scooter or a commuter e-bike, chances are you’ve seen a Lishui controller. These compact, robust units are everywhere—from Ninebot (non-Segway) budget models to generic OEM scooters.
But here’s the catch: Lishui controllers are notoriously locked down from the factory. Programming them isn’t like tweaking a VESC. You need the right tools, software, and a bit of patience. lishui controller programming
In this guide, I’ll walk through what works, what doesn’t, and how to safely adjust parameters on a Lishui controller.
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.
Goal: Use a 13S lithium-ion pack instead of 10S. Method: Modify the voltage divider resistors (hardware mod) AND change the low-voltage cutoff (LVC) in firmware from 30V to 39V. Risk: Capacitors rated for 50V may blow if your 48V pack charges to 54.6V. Goal: Go from 25km/h to 35-45km/h
| Parameter | Stock Value | Performance Value | Notes | |-----------|-------------|-------------------|-------| | Speed Limit (km/h) | 25-45 | 55-80 | Do not exceed motor RPM rating | | Battery Current (A) | 20A | 35-45A | Monitor wire/connector heat | | Phase Current (A) | 60A | 90-110A | Increases torque; risks MOSFET failure | | Regen Brake Strength | 20% | 40-60% | Test on downhill first | | Throttle Mode | Speed | Torque | Torque feels snappier |
Lishui controller programming is legal for off-road use, private property, and racing. However:
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. Various GUI applications exist, often labeled generically (e
On a user-accessible Lishui (non-encrypted), you can adjust:
What you cannot change without special firmware:
