O/k think about it this way.
You can buy a lot more grade B cells for the same cost of buying only grade A cells.
Its possible to put together a much larger battery, with a higher total amp hour capacity (per dollar) with grade B cells.
So why the insistence on 304+ amp hours per cell ?
Unless you are severely restricted for the extra space or extra weight, of fitting a few more cells, the grade B cells make far more practical and financial sense.
That is why the EV people insist on using the very expensive hand picked cells, they have very severe limitations on size and weight.
For a home brew solar installation, it usually comes down to minimum cost for maximum amp hours capacity being the best deal.
If you absolutely must have that extra edge in performance, for whatever reason, just pony up the money and stop complaining.
