I just wired up this bms to my Growtt inverter, turned everything on and I am not getting voltage to the inverter above 8V from the 48v lifepo battery.
I have a red lights on the communication board and a flashing red light on the bms but the onlne manual I have says nothing about any of the meanings of the led's.
Also, I note that on the bms itself showing the cell censor wiring, it shows cell B8 twice! I just chose to hook the positive from B8 to ONE of these and NOT both.
Does anyone know where one can obtain a more complete manual for this bms?
 
Does that BMS have a UART port on it, or a Bluetooth module plugged into that UART port?
