By all means a second battery should be installed

momentarily dropout, I have concluded that is best
to use 2 single-pole
battery switches. That way one can have either or both
batteries
connected at the same time.

I saw the light when Jim Hendrix brought his sailplane
to Caddo Mills
for Wing Deturbulator flight testing, and it was wired
like that. You
will hear much more about that amazing new invention
at the coming SSA
Convention.
