Upgrade display - what's compatible?

[DougalDogHead]

Hi all

As the title suggests I'm looking to upgrade the display for my ebike. It currently has what I believe to be a Kingmeter 790 with a none-waterproof connector such as the one pictured below.


I understand that the controller is a LiShui controller as pictured below


I believe that this is the connector for the display, though I could be wrong.


I don't know how to determine which displays will be compatible, so I'm wondering if anyone would be able to advise, please?

Thanks in advance!

The 790 isn't digital display, it is analogue so one can't use an lcd or for instance a km 880 as that is digital.
Your only way out is to chnage controller and display as a matching pair.

I did think about doing that. Is there anything I need to be aware of in terms of compatibility other than voltage? I can't see any identifiable markings on the motor so I don't know much about it other than it being 250W 36V.

The main reason I want to change anything on this bike is because it is limited to 13mph; I read on the German version of this site that LiShui controllers limit speed to 13mph unless they have a digital display, but if that's not possible with the controller that I have then I'll have to swap the controller

I don't know which hub you have as the pic doesn't open in a new pane.
The controller is 15a max rated so one could use a kt dual voltage contorller and any one of a dozen displays, one will have to buy one with sm type connectors as yours is. One might have to chnage the PAS wire order if it doesn't match as well plus some connectors may be of the wrong mating.
Show your wiring better with every connector visible inc the motor connection.

Here's some images of the wiring:


It all looks very nondescript to me.

There's also 3 unused cables on the controller, but if I'm to replace it, I doubt that these are relevant. All 3 look like this:



The only information on the motor itself is what I assume is a serial number, because a Google search for it returns no results.

The motor is without halls an unsensored one.
Pic one is Blue/Yel/Grn motor phase.
Red/Blk battery.

Pic two.
Gry/Blk x2 brakes.
Blu/Blk/Red PAS.

There are two connectors I'm not sure what they are for.
Thin Grn & Blk/Gry goes in and only Grn seems to exit and the Red/Wh & Blu/Wh, both lead to the same place. Some have cuise mode so could for this and needs a long press on mode button.



Pic three.
That one or one of the others may be a throttle, though the wire colours don't look right for a throttle. I would expect one wire to be White.
