First time towing in the dark last night for several hours... running with batteries in "store" mode. I have the factory-installed solar charging but when I finally stopped my batteries were at 70% (maybe around 12.4 volts). I verified (prior to trip) 12V
feed from TV. Was wondering if TV should still charge batteries even with these conditions. Age of batteries explain the 70%, but normally show 100% in the daylight due to solar charging. I assume if the TV charge was getting to the batteries it would have been 100%. Any thoughts?
