I bought an ant bms and an lcd screen. I have the bms up and going and can configure it via Bluetooth app. However, I don’t see any way to connect the lcd to the bms to get the cell readings and info. I can get the lcd to power up but it seems it has uart connection (I thought it was Bluetooth). There is no uart connector that I can find on the bms. Am I missing something? Is there a way to connect these? Pictures is what I have.

Thanks!

The BMS should have 4 pin connector as shown on right. The supplied cable plugs in here and other end into LCD. The loose black & red wires are for LCD power which I think is 24 to 150V.

Have never used the display. View thru phone or Home Assistant.

I have my display working but it came with a six pin connector on the cable, does anyone know what the name of the four pin connector is so I can order one? (I have it working by carefully pushing contacts onto pins)
