Something sounds strange here...80AH battery taken down to "1/3" and being nearly fully charged with an 80w panel....
Can someone that knows more than I do the math here......Just trying to understand this better.
Also, taking a battery down more than 50% causes irreversible damage...no?
Given the "meter" I wouldn't even attempt to do any math. The supposed 1/3 is not even close to a real measurement.
Discharging deeper than 50% is fine if it's done occasionally. The deeper you discharge a battery and the more you do it the shorter it's life. Technically every "cycle" of a battery, no matter how deep, reduces it's life. They are only good for so many cycles. More if they are shallow, less if they are deep.
