Minimum voltage looks like 2.2 per cell or 8.8 volts to get full rating. Inverter shuts down at about 10.5 volts.
How much of the power have you got at 10.5 volts? More than 90%?
not sure what you talking about they stay above 12.5 untill there 86% discharged. here is a chart for you. I guess the 8.8 could be absolutly stone cold dead but we dont use that part of the range when we talk about there capacity , thats the " 10 or 20% that we stay out of to increase life. I think 5% wold be the lowest you could use them and stay above the inverter shutdown but I would only go down to roughtly 14% personaly.
