I charged 1 battery after I flew and depleted to 10%, then put another battery on that showed 7% and charged it full, and put the first battery back on after depletion to 10% and it took it back up to 48%.
Hope that helps,
Joe
Got one for my trip to NM. Worked great - got 2.5 full charges on it. Saved me having to bring more than 4 batteries - charged with MP2 charger just fine.
I have both and will testing them together this coming week. Since the goggles sync directly while using my iPad (already tested) I don't see why the goggles and the moverio wouldn't also work simultaneously
