I dont think 90 min of Genny time is enough to get a full charge. It might be more like 3 or 4 hours? So you might kill your bat. life over time by not charging correctly.
I would also figure out some way to get the camera disp off.... that sucking a lot of juice. Is your backup display part of the radio in the cockpit area? Can you just shut it off totally (I know I can in mine). Or are you listening to the radio the entire time? If you are ..... can display the radio screen only and save some juice.
But it sound like your battieries are still doing pretty good (for now).
