I finally found out! There is 8 pin RJ45 marked rs232 on the BMS sc0500a-100s (I have 7 pylontech H48050 connected to the BMS). I connected a normal ethernet cable and wired: * white green cable to pin 2 on the 9 pole dsub female * green cable to pin 3 on the 9 pole dsub female * brown cable to pin 5 on the 9 pole dsub female Connected the dsub to the serial port on the PC. (USB to serial adapter). Started putty and opened the port on 115200 baud. Press enter and the pylontech debug menu is opened. Quite impressive of all data you can read outl Everything from statistic, cycles, voltage on each single cell, alarm and event history. The pylontech enginners has made a good job and I'm happy they has left this debug info open. It will make it very easy to troubleshoot if/when a battery fails.

Number of cycles 56. (There is a lot of commands to select between)

Is there anyone that has found out what the pinout are for the 8 pin RJ45 serial port on the powercube batteries H48050? And as a follow up question... is there anyone that has tested if the Batteryview program is compatible with these batteries? (That was my idea to test when I had found the pinout...)
