Yes, I'm quite aware the LX5000 is a vario. When I used the term "radio",
I was talking about his actual radio, which he earlier said that he optimistically
assumed might work at 10 volts. I thought that should be obvious.

Sorry! My focus was on the LX5000. It would be a most unusual radio that
would transmit on 10 volts (basically a dead battery). If it were me,
I'd try the radio on the ground on a 12 volt battery like the one in the
glider, and see how low a voltage would satisfactorily operate it,
before going to a 14 volt system. I used to use 14 volt packs on my
older gliders, but it was always an irritation having an additional cell
that didn't fit in the battery box, and cost almost as much as the 12
volt pack. Some of the radios I used back then turned out to be
satisfactory on the 12 volts, so I quit using the extra cell on them.
