This one is probably for you. Make sure you map the correct GPIO pins. Sometimes different knock-off ESP32 switch them up.

I am using a nodemcuv4 ESP8266 over RS485 UART with good results. There are a few limitations of the UART communications. You can't control the balancing. Which is fine for me, I want the BMS to control when balancing kicks in. The drilldown details of each cell is also not available (ie. each min/max cell voltages and resistance).

If you need these the bluetooth connection has more (ble). Go figure... ¯_(ツ)_/¯
