I am a long time customer, having had a stack of Lifepower4 V1 batteries running for a couple of years now. I bought a pair of Lifepower4 V2 batteries to test before buying a full stack of 16 batteries (80 KWh is the legal limit here in California) for a new deployment.
I have been unable to get the V2 batteries to talk to me on their BAT-COM ports no matter what I do. I have tried pins 1&2 as well as 7&8. I have tried 9600 baud and 19200 baud. I have tried various protocols.
I can talk to the RS485 port no problem using BMS-Tools V1 or using Solar Assistant running the MODBUS protocol.
But I cannot get the BAT-COM ports to work at all in any way.
Can you please tell me how the BAT-COM ports are supposed to work, ideally to talk to my V1 batteries? I have updated my V2 batteries to Z02T05. I have updated my V1 batteries to Multipack.
I need to know if the V2 batteries are supposed to talk RS485 on their BAT-COM ports? If so, at what baud rate, on which pins, and talking what protocol for battery to battery communications?
Thanks!
