I am with Forest. I am concerned about the inverter/charger setup. Yes, I think the setup is keeping the lithiums at too high of a voltage.

I have mine setup slightly differently, and I do “float” mine at 13.4. So as long as I am plugged in, the bank stays at 13.4, with normally about 10 amps or less current. If I go off shore power for a short period, say 12 hours or less, then when I plug back in, it goes into float mode with a higher current. If I go off longer and deplete the house bank, the charger goes into bulk mode at 14.4.

I will post my settings this morning for you to compare.
