did you ever explain what shorted? did it short again a second time when you got this new BMS?
your pack has full voltage, the output of the BMS is half that because of the leakage. if you put a resistor across the leads it may drop to zero. if current flows when you put the resistor on the leads, it will get hot. if it gets hot, your BMS is functional.
i still think the BMS is shut off because the cells are outa spec somewhere. the BMS is behaving normally, nothing wrong with it or the previous one, imo.
if you shorted the output of the battery again then it may have shut off because of the current surge.
The new BMS was installed professionally by an electrician. I don't think he shorted anything i cannot confirm. I was soldering a C14 connector to the output side of the battery and the spark came from there when i accidentally shorted it. I did not unplug the battery from the BMS as at that time it was all sealed up. After the spark, it started to behave like this which is why i thought i destroyed the BMS, but after a new bms its still the same.
