you seem to not understand... the BMS that does not discharge does NOT go into any cutoff. No errors logged (cutoff would be logged), discharge is shown as ON but MOS gets not polarized - 0.63V drop over P- and B- !
If you read my post correctly, it was saying "EXAMPLE picture, NOT mine) - to demonstrate how the screen looks like.
IN my case, this morning the problem happened again and the two BMS apps show:

Now it happened the other way around! JBD BMS did not...
Now again same situation, but banks behaving swapped! It is night time now, so nothing comes in into the packs:
JBD bank stopped to discharge (current 0A), bat voltage hoovering at around 26.9V, BMS shows "charge ON discharge ON"
JK bank discharging, battery voltage at around 26.4V...
Ah and then I pressed the emergency mode knob to ON and it started discharging (and apparently charging the JBD pack at 2kW, sucks).
Really no errors logged, is the BMS faulty?
Hi
I have a strange problem: I have 2 DIY packs, both 280ah 24V. One uses JBD BMS (xiaoxiang app) and the other one JK BMS B2A8S20P.
The JBD pack is older it was working like 6 months here and I added the JK pack 2 days ago. Both go onto same 24V busbar.
So far all looked good, however this...
