NiMH are generally manufactured in smaller sizes, then combined to make
larger voltages/currents.  Even if you did find a single cell that can
provide over 5Ah of energy it would be significantly cheaper (while
heavier and using more volume) to use several smaller cells to make up
that storage.

Also keep in mind that as they charge and as they discharge they
generate heat.  A larger cell is going to have a harder time dissipating
that heat than several smaller cells.

Look into lithium ion rechargable batteries for larger capacity in a
smaller/lighter cell.
