I have installed a Daly 4s 12v 100A BMS attached to 4xCATL 302ah cells connected in series. My question is about current polarity. It appears that the battery systems appear to be working correctly, well at least I believe it is. However when the battery is drawing current, the Bluetooth ap is showing a positive current flow and when charging the current is displayed as negative. I was under the impression that these should be opposite. The B1 terminal is definitely connected to the battery negative.
Am I missing something here? Have I got a problem or this some sort of setting?
