:man_shrugging:

I disconnected B300K and it gave me the sasme result.
Idk man, I think I’m gonna call it. Esp if you haven’t encountered this.
And again - thank you for babysitting :handshake:

Try running:

py ble_read_cells_cli.py 1C:69:20:8E:2F:1E

OR

python ble_read_cells_cli.py 1C:69:20:8E:2F:1E

If it does the same thing, it might be due to BMS unable to read the voltages due to it being deeply discharged perhaps? What is the SOC of the unit?

23

Nope, didn’t work.

It was charging at the first attempt with the SOC at ~90%.
Now it’s 100%, still connected to the grid.
It was in passthrough mode as a UPS in both cases (if it matters).

24

Disconnect from grid and supply a constant load to emulate the conditions of AVG’s setup. I am not sure if UPS is interfering or not, but in AVG’s test, he did it disconnected from grid power and supplied a small load to the battery. I would do the same.

25

Disconnected, gave ~200W AC+USB load, and tried all variations of the command. Nothing.
I give up; it was a good try :handshake:
@BLUETTI_CARE and again - read this thread and make this an official tool inside of the app; hide it behind Pro mode or something.

Hi @VSM, thank you for your concern about this issue. However, the customer’s request is beyond what we can provide, so we regret that we are unable to assist.
