I have two 6500s and 12 Lifepowers as a secondary off-grid system (other system has been powering my tinyhouse off-grid since 2020) which powers two EVs and will power a walk-in cooler and other stuff on our farm. This system has been in use for a couple months and I just did a warranty replacement of both 6500s due to P80 errors. Now working fine so far.
I have been trying to upgrade the Lifepowers' firmware and getting comm issue using BMS test software. I'm able to open the port instantly and can see all the batteries in the bank, but mostly getting bad reads (maybe connects 1 to 5% of the attempts) and often has blank columns while looking at all 12. This would be ok since in the long run monitoring batteries should be rare, but when trying to get boot info for updating firmware it fails every time. I tried leaving connected a while hoping it would eventually get boot info, but keeps saying failed connection. Using the EG4 cable with exposed pinout wires and they are pins 1 and 2 of course since I am able to read the battery status (intermittently).
I have address set to zero, I have dc breaker to 6500 off, have the battery to battery com cable disconnected and even tuned off the other 5 batteries in the rack of 6.
I messed w various baud settings but in seeing the eg4 videos the default settings should work.
Any ideas? Again, I am able to read the battery but it mostly shows a red text fault and only occasionally green in the bar info tab whether looking at just 1 battery or all 12.
See pic which shows status for battery but also shows address 0 in red and status in red at the time of photo. Status only updates occasionally instead of always being connected.
I'm using a newish workstation laptop which requires a USB C adapter. This laptop has been used to update firmware on the 6500s no problem.
