Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

70% of what? How was the 70% measured?
It is certainly possible that the batteries could be so reduced in capacity from chronic undercharging that they would drop to 11v under high inverter draw when down to 70%, when at full capacity they would stay over 11v.
Off grid with solar for long periods does require the occasional overcharge using solar unless you get shore power from time to time. It can be awkward to arrange doing the overcharge while camping. The split bank routine is one way. (run the rig on half the bank while overcharging the other half, then switch) but it can take several days and needs nice sunny days in a row as well.
Solar lets you get away with less battery except for that high inverter draw. Time2roll had that happen with his old bank, but his was old age not undercharging.
I can never understand why people insist you need more battery with more solar, when in fact you can operate with less battery because you have more solar. How much battery you need is a separate calculation such as for running the inverter at night. There is another factor for being able to stay operating with no sunshine for x number of days, but that is scenario dependent.
