Batavus 5-level PAS controller and aftermarket displays: will 3-level display fit a 5-level controller?

[egils]

Hi. I have a Batavus ebike with their controller and led display with 5 levels.
The display only have level indicator and battery indicator and a power button.
I'm not happy with the display quality (the power button breaks and the display stops working) and would like to use an aftermarket part instead.
I found this cheap 3 level display but I wonder if it will fit?

I also found this 5 level one and wonder if that would be easier/better to fit?

Or this one with a 4in1 bus cable?

Is there a standard/guide somewhere about this TX RX cables and the bus and how they work?

I can post the wires and connections in the bike if neccessary.

Nearly all 5-level ones are digital. 5 wires, two of which are Tx and Rx.

A 3-level one won't work if it's analogue, which many are. A digital one will have 5 wires, but also an analogue one with lights will have 5 wires, so it's important that you look at the description and specification.

Even if you get a digital one, it might not have the same comms protocols.

Sorry to be negative. It might work, but you won't know until you try.

Thanks for the help!
I own a bike workshop and I am a customer of Batavus/Vartex but I'm not sure they are ready to help with anything else than selling a new display. I will ask them for specifications/data sheets and see what I get.
Has anyone reversed engineered all this before? Anyone I can contact for help somewhere specifically for Batavus?
We really need some standardization on ebikes. It seems to me like the wild wild west.
