Joe,
Battery voltage for a LFP battery is not a good indicator of SOC as the discharge curve is very flat. That¡¯s one of the advantages of LFP, it provides the same voltage throughout the entire capacity, only dropping at the last 5% or so of charge. The only way to know the SOC is to have a smart shunt that counts amps in and out.

That¡¯s very interesting. Do you know what the battery voltage typically is at the end of a charge cycle, ie sunny day and you get back on the boat after a week?
