They can't be arrayed - several in series will destroy some cells at the
discharge limit, unless I put more annoying protection circuitry in

I find NiMH difficult to handle. They're not hands-off, they're painful.

They have 1/3 the voltage, at about the same Ah. Very expensive for the
energy I am looking at.
