| Symptom | Likely Cause | Programming Fix | |---------|--------------|------------------| | Motor stutters at start | Wrong hall angle | Not adjustable – replace controller | | Weak acceleration | Current limit too low (P12) | Increase P12 by 5A max | | Overly strong regen | Regen level = 5 or 4 | Set P14 to 2 (smooth street) | | Speed limited to 25 km/h | Speed limit (P08) set to 50% | Raise to 100% | | Battery cuts off at half charge | LVC too high (overprotective) | Lower LVC by 2V only (e.g., 42V → 40V for 48V system) |

: The Lishui Controller LSH Programmer allows you to upload .lsh firmware files and adjust max current or undervoltage limits.

For those new to Lishui controller programming, I suggest starting with the example projects and online tutorials. Joining online forums and communities can also provide valuable support and insights from experienced developers. Power off the controller and disconnect the programming

Lishui differentiates itself from competitors by performing all software and hardware development in-house, employing a dedicated team of nearly 60 engineers. Their product line is segmented into three main markets:

Controls how quickly the motor kicks in when pedaling.

| | Description | Options | |---|---|---| | Base under-voltage protection | Battery cutoff threshold | 21V (24V battery) / 31.5V (36V) / 42V (48V) | | Current limit | Maximum amperage drawn | Model-dependent (e.g., 25A for LD-LS10-C) |

By unchecking the "Keep Current Settings" box, users can often manually adjust the maximum current and undervoltage cutoff limits before flashing.

Lishui controllers use files for firmware updates. These can be:
