Meade 18V power supply as a charger?

Bruce,
if they look neat, as opposed to car-like, they're most likely gel
cells.
If you got six of those, you can wire them up in series to charge them
as three separate, two-cell 12V blocks!
In any case, your 12V to 120V- to 18V setup should work fine, the only
catch being the energy waste which may range between 60 and 80% of
your total power draw. But if your Rube power pack is big enough, I am
sure you can put up with the inefficiency!
Just make sure you do not discharge the battery too much, because the
voltage drop sends more amps into the 12-120 adaptor which may fry in
the process of volt-amp compensation.

Hari,
My guess is that the batteries came from the electric kiddie cars you can
get for $150 or so. I can recharge 2 in series, but then of course there is
the 3rd battery. Do I charge that separate at 6V, or rotate in one of the
reserve batteries? I think the recharging procedure would begin to need more
of my attention than I want to spend! The Goldberg system does work,
although I've run it dry (without damage so far) when I'm at Stellafane or
another star party and try to get more than one night out of it. The
inverter might have some kind of safety device, when the battery gets run
down to a certain point the inverter gives a couple of beeps and shuts
itself off, even though there is still a fair amount of juice left in the
battery.
Thanks,
Bruce

Have you looked into the possibility of buying an 18-V rechargable
battery pack and a charger? That would be the best solution to powering
your LX200.
