I've got a guestion. I currently have 3 new 100amphr batteries and when I'm home I usually use a free standing 85 watt solar panel plugged in whenever the voltage gets down in the low 12's. I then charge the batteries back to 100% charge state and unplug the panel. Is there a preferred percentage to let the batteries drain to before charging back? I want to get the longest life out of the batteries as I can. Can I leave the solar panel plugged in all the time? The controller I'm using is a Go Power 25 amp.
Thanks in advance.
