Anything new in batteries for solar
I have four 31 size lead acid batteries. They are heavy and you only get to used half their capacity. Is anything come up recently that could be a reasonable replacement--probably lithium?

That is why LI is so attractive even at the premium price.
However the Firefly, and Outback batteries can handle undercharging for 30 cycles and still come back to full capacity. They don't have a price advantage over LI, and of course they are heavy as the dickens. But they can be charged in extreme cold without dying.
I solved the charging problem with twin banks that could be switched so one bank was in use and the other was charging.

Li handles undercharging just fine. I rarely equalized my acids because it's so darn difficult to get a full charge first.
