Boon-docking now for day #4 with no issues - 100% solar and lithium. Each day has had consistent daylight with full charge by EOD with lowest charge only reaching 60% before mid-morning when the sun begins to hit the solar panels again.
However, last night (day 5) the voltage reader has dropped to 9.47V - but the charge on the reader still says 73% charged?
What am I missing? How do I get back above 12V?
