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?

it has a 20amp charge current, according to the specs, and a max discharge of 50amps
yes, those rates are extremely low for Li, It it most likely a limitation of a paranoid BMS !. controlling rates like that may give the
cells a good lifespan an protect from user abuse.. but in the real world it will restrict application to very few cases.
