Thank you
In the first rating there are pictures what has do be done, but my R4875G1 has a different PCB layout
You only have to pull out the fan connector, plug in the small pcb, plug the fan connector in the small pcb, solder two wires to the CAN-BUS, glue the screen in the plastic part and glue the ESP to the backside from the screen.
If it works, I do not know , I managed to rip off the conecctor for the small screen, but it was definitly my fault. I did not realize that there is a lever to open the connector.

Finally I ve got this one.
It's working like a charm but only when is connected.
If I'' disconnect it, the rectifier (After power cycle) it's back to the standard value (53.8V).
Any clue to change the default parameters please?
thank you

Got it running in my R4875G1, touchscreen is working well for settings, but I am still waiting for bluetooth app.
Thank you. I didn't received 
and I m still waiting
But I just received the standard controler.
Everything is working fine but I m unable to set the parameters - as default after restart the rectifier.
So all the settings are valid but not saved as default .

Does the seller send the app? On which phones? IOS, Android

I have a program on my Android, but I didn't install it. I have an iPhone
Can you share scematic modul.. what IC u use?
If you know the name of the app, there are a few APK archive sites out there. And the wayback machine site.
I bought it from another seller. It might be different. The middleman sent it to me on Telegram. I wanted to attach it here, but it's probably too large, 9mb, so it didn't work. Try this. HW智能充电器APP下载-HW智能充电器APP下载

This is for analog adjustment. From some Chinese forum. You need to know the points to connect to. It's unlikely you'll succeed, as there are different revisions of the power supply units.

Thanks.. I will study it first..
The default voltage is changed on the controller using a PC through the serial port. I haven't done it myself, but it seems they wrote about it here. I found this picture for myself.

I bought the same thing.
But in the settings, I can't set the current higher than 30A.
Have you installed the program on your smartphone? It may be set to 30 Amps.

Just checked it, I have got the same 30A problem, and I have installed it in an R4875G1.
I have the program HW-App already on my phone, but that is not working with the board I bought.
That needs a QR Code to connect, my touchscreen shows no QR Code.
I got a WeChat "picture" download link from the seller, but I do not have WeChat.
Anyone which can make a download link out of this?

The hw smart charger App always wants to scan a QR Code.
The screen of this kit does not show a QR code.
Installed WeChat, scanned the picture, downloaded a program, which wants and scans Bluetooth connections , but still does not find the charger.

I finally made it to run the program from the seller sent through WeChat.
It is basically the same as the hw smart charger program and I still can't change the 30A limit or enter higher numbers.
Very interesting thing is, the phone does not show the Bluetooth device in the list, but it is connecting to it.
Negative point WeChat needs all possible rights from the phone to connect to the device.
But I did not had to enter my credit card number and the code for it
