Hi,
Re firmware 20210511-1.01T on the Daly smart BMS 120A 20S.
When the temperature falls to under 7C, the BMS MOS discharge switches off. Changing the discharge minimum temperature even down to -25C does not help.
I have seen the same problem with 3 units of the Daly smart BMS.
Attached is the PC Master alarm log showing various errors on switch on, that subsequently are cancelled, but the MOS still stays off.
I asked Daly for a firmware upgrade but the one I received bricked one unit :(
Hope this helps any fellow sufferers.

Also firmware 11_221122_001T that came with a recent order of 5 x 150A 20S BMS is faulty and turns off the discharge switch when ampage drawn is over 30A. These BMS are very unreliable. My advice is to try another brand.
