Switch 2 usbc meter readings

Does anyone know what readings are normal for a switch 2 motherboard with no battery connected? I have 15v and 0A draw. I’m assuming it’s like the previous models and the readings are healthy?

I bought the unit as parts and I’ve been working on it. I found the bms had gone into protection with corrosion on the connector. My only issue is I don’t have a working unit to compare it to
