Yangtze 48V 100AH Battery BMS Settings

Hi,
I grabbed a pair of Yangtze 48V 100AH Battery second hand.
The seller said he bought it from China, but never used it because his Inverter (Growatt) needs a communication with the battery.
I bought an Hybrid Inverter EASUN 5,5 KW, which does not need to communicate with the battery.
System seems to work, but the battery cuts out above 50.5 V and at/below 47 V.
So I can only charge /discharge the battery partially. Especially when the load is high the battery is gone, needs a manual restart.
To analyse the problem I would like to read out the Battery status (with and without load) and the BMS settings.
I opened the case, was only able to identify the Manuufacturer of the cells (EVE 105AH) , but not from the BMS ( Topband?).
There are two RS485 ports on the front.


I bought an RS485 to USB Converter

Q: Is there a recommandation for a Software to read out the Battery status and the BMS settings ???

Thanks for any tips and advise
Frank

Hi, did you find any communication software for your battery? I also have a Yangtse battery and can get no info on BMS communication software for it..
