Need Help: Lishui Controller (LSW913-62-6F) Protocol Mismatch with M5 Display

[othmane]

Hello everyone,

I need help with my e-bike setup. I am using a Lishui (LS) controller, model LSW913-62-6F (36V).
1. Wiring Check:
I have attached several photos of my current wiring. Could you please check if the connections between the battery, motor, and the main harness look correct? The system powers on, but I want to ensure everything is in its right place.
2. Display Problem:
I am currently using an M5 LCD display (Green Julet 5-pin connector). While it powers on, it doesn't show the speed or any motor data. I suspect a protocol mismatch since the M5 is likely UART2 and my controller is Lishui.
3. M5 25P Compatibility:
Does anyone know if the M5 25P version is compatible with Lishui? Or should I stop trying with the M5 series altogether?
4. Recommendations:
Which display models are confirmed to work with this specific Lishui controller? I've heard about KD21C or SW102 (Lishui versions), but I want to be 100% sure before buying another one.


Thank you for your expertise!

Hi,this is almost certainly a protocol mismatch

The Lishuis often use the 5S protocol. There are many cheap China displays, that can be set from No2 protocol to 5S with parameter P20. But it depends on the displays firmware, if it is implemented or not. So it's a lottery, if it works There are various manufacturers like Key-Display or Kingmeter that are offering UART displays with 5S.
