Once upon a time, car battery manufacturers made 8 volt batteries.
These were for cars with 6v systems that were aging, and a couple of
extra volts made up for a lot of problems.
Might take a bit to figure out how to charge them, but a 6v plus an 8v
battery would give you a really clean supply just over 14 volts.

Yes, but the battery chemistry also matters. The "normal" operating
voltage of LiFePO4 batteries is at least a volt higher than lead-acid,
and the discharge curve is flatter. The problem is that LiFePO4 is
currently a lot more expensive, and the chemistry requires a special
charger. Prices are gradually dropping, and eventually that's likely
where I'll end up.
