I got the battery specs from Trevor. The batteries are pretty tough and accept a wide range of voltage inputs. Other than shore power float being a tiny bit low, everything is within spec. Also, since the solar panel float voltage is at the high end of the range, the two together should balance out.
|Max Bulk Charge Rate||Absorb||Float||Notes|
|Battery Mfg. Recommended||40-50% “higher possible”||14.25 – 14.6||13.6 – 13.8|
|Magnum Shore Power Charger “AGM”||132 (observed)||14.5||13.5||Float is a tiny bit low.|
|Solar MTTP “Sealed”||??? Nothing observed||14.4||13.8|
Note that temperature has a big effect on these ranges as well.
