Do you really need to carry 260 pounds of battery? What are you running? You
should connect them to a real charger periodically to get them off gases and
desulphated or you will loose the capacity anyway. Regardless of current
available, battery charging is a time dependant process. You have as much
house battery capacity as my 39' motor home.
