Just so happens he is right - even if not for the right reasons. MUCH
better to increase voltage by connecting in series that to increase
amps by connecting in parallel. A "battery" by definition, is a
series of cells connected in series. Parallel connection of cells is
much more likely to run into problems down the line.
