Maybe a dumb question. I have a lot to learn. I bought a BVM-712 to install in a new to me truck camper this weekend (2013 Lance 825). I will use the VictronConnect Android App to monitor. I note that the setup wizard will ask me to input the battery capacity. Unfortunately, I don't have a clue what my battery's AH rating is, and would appreciate advice on how best to proceed. The battery is a single 12 volt flooded lead acid. The label on top reads "MARINE-RV" ;"EXTREME CYCLE DUTY"; "Distributed by ABSS, Everett, WA." That, along with a yellow "8/18", is the only information provided. (I have reached out to the named distributer, but haven’t received a reply yet.)
My question is, how important is it for me to ascertain the battery’s capacity rating and input that into the app? Is it required for State of Charge and Time to Go? If I just guess, will the monitor self calibrate over time? If I should instead manually determine the capacity, any suggestions for how best to do that either using the BVM itself, or a DVM?
