And LIFEPO4 12V 100AH  pre-made batteries  vary in quality

In general, the full encapsulated plastic nice looking types are built 
with lots of B grade cylindrical cells.

The best are built with single prismatic cells. IE 4 cells for 12V , not 
400 !

The cylindrical B grade cell type are about half the price, but they 
never last as long.

Examples of quality battery brands  built with prismatic cells-

CALB, GBS, Thundersky. There's probably some US made, now, also.
