Sorry friend, but it don't work that way. Connecting two batteries
in series will cause the resulting voltage to be the sum of the two.
Connecting two batteries of the same voltage will cause the voltage
to be unchanged, but the total current available will be the sum of
the current available from each battery. This is why you are able
to jump start a car by connecting the cables in parallel.
BTW, I wouldn't ever connect two batteries of different voltages in
parallel for an entended period. The higher voltage battery would
destroy the lower voltage one.
