Good Day
I am having issues with communicating to the bms of the MaxLi LifePo4 3.5 Kw 48 V Lithium Iron Battery (SKU: YS-48-70). The Rs232 and 2 x Rs485 ports do not transmit any data (confirmed with serial monitor and an oscilloscope). Is there any special code I need to send before receiving data? I'm really only interested in getting the SOC.
There's also a CAN bus port, I can see there's some sort of signal being transmitted on that protocol, however the signal is repetitive and does not look like a CAN signal.
Any help will be greatly appreciated.
