Hi all,
I couldn't wake the Daly 250A (no fan) BMS up with a load on the battery, so I shorted B- and P- as per some videos/threads. Some sparks, but still no luck.
In the end, I used the two pins that can supposedly be connected to a button to restart the BMS.
It woke up.
However... I didn't notice it before so I'm not sure if it was caused by the short or not.
The current flow reading (amperage reading in the app or the PC software) is jumping all over the place.
According to the Victron shunt, it's currently charging with 39.5A - shunt connected at the P- side of the BMS.
Current reading on the PC software: -19, -67, -39, -23 etc. All over the place.
When discharging, the load is higher and so are the jumps, they're so high, that the 'over discharge protection' kicks in and the BMS shuts down.
Basically, I'm unable to use it (ignoring the capacity issues). I wonder if the internal measuring electronics could be damaged by shorting B- and P- (several times), even though I just touched it with a 2.5mm2 cable for a short while.
Any help appreciated.
With regards,
Martijn
