For anything larger than about 500W that'd become untenable because at 12V as you'd need cables that can carry in excess of 50A.

UPS systems start connecting the batteries in series to provide higher voltages for this reason

Or multiple cables, just as PC power supplies of 500w+ have, and in fact some of their power is delivered at 5v.
