In this configuration each read causes more than 1KB data to flow through all cells to reach the master, and this morning, zero communication error after almost 30.000 reads thus approx 30MB data
I wonder if your BMS can be set to bottom balance LiFePo's. On his last show Jack Rickard explains the whole matter in detail better than I do. If you care to watch the section on the subject is at around 30:00 into the program. This guy is an encyclopedia on batteries so it would be interesting your opinion on what he says. He has a lot of years of experience in these matters.
