Axpert King 5000 and Deye SE-G5.1 Pro-B lithium battery settings and cable connection RJ45 BMS

[NILES]

Hi guys.
I setup system with AXPERT KING II 5KW 48V and Deye SE-G5.1 Pro-B lithium battery. 
Main (U1) Firmware 50.06
Display (U2) firmware 19.16
No solar panels, just for work as an UPS.

I made the RJ45 cable according to the pinout diagram in the picture below. But got error 61. Tried set battery type as "PYL - Pylontech battery" and "LIC - 3rd party Lithium battery" - got error 61 on both.
Is there any chance to make RJ45 cable work on AXPERT KING II 5KW Inverter and Deye SE-G5.1 Pro-B lithium battery?
Deye SE-G5.1 Pro-B lithium battery to output battery information to the inverter can use:
1.  the CAN protocol (baud rate:500kbps)
2. the RS-485(baud rate: 9600bps)

While the cable doesn't work, I'm trying to set the battery as USER type.
Voltages are:
12 - 48
13 - 51
26 - 52.5
27 - 51.8
29 - 46.0

Problem:
The battery does not charge full, only 3 leds of 5 on the battery are lighting. At the same time, the inverter says that the battery is fully charged.

1. Need help to get the battery to work correctly as USER type.

2. Need help to make RJ45 cable work.

The Deye seems to be a 51.2V LFP battery, meaning it's probably 16S; those settings are for Pylontech, which is 15S. So multiply the voltage settings by a factor of 16/15.

The inverter has no idea of the correct SoC with battery type USEr. It is basing the SOC on crude lead acid voltage levels.

For the cable to work, you first need to know what protocol (comms and hardware) that the Deye BMS is using. It's quite possible that it's not one of the several that Voltronic support so far.
