Cold last night, about freezing, 32F, no heat in the van at all, and I was not in it. This morning, still freezing out, I checked the battery temps in the Victron App, and each showed ~66F. I also noted the temperature offset setting, and mine showed +38F and "Resulting temperature: 124F. I have never touched that setting on my three batteries. I thought maybe I could adjust it to match the ambient temperature, so I tried. I could adjust the offset down to 20F, but the "Resulting temperature" then read 106F. Sorry, but none of this makes sense to me. Any suggestions? I do not want to be charging if below 40F.
