So my 4 16s cases with the JK Inverter BMS were delivered last Sunday. They are white color and have the JK touchscreen. Not a fan of how the screen mounts but it works. The only thing they forgot to add was enough screws to mount the BMS and the communication board. The new JK BMS was able to communicate with my Sunny Island 6048 using the CAN port with Pylontech protocol.
Overall I'm very happy with them. I do wish they start offering a stacking design though. That is the only downside of the of the Luyuan boxes.
