Does anyone have a link to a really good how-to on battery maintenance. I understand it is best to run your bank down to 50% a few times when new but I am not sure if it's best to leave the charger on after this to keep them topped off or if I should turn the charger off and let the batteries drop to 50% before charging them all the time or what. I am using my newly installed battery monitor to determine SOC for the first few 50% cycles.
