Please keep us posted on this.

I would think that there are a lot of people that would
be interested in any unseen "gotcha's" that crop up.

I, for one, would not opt for a 'sealed' system with a
gel-cell within the 'sealed' area. Perhaps it can be
vented (anyone recall the tubes used on motorcycle
batteries that vent any 'fumes' down and away?).

I also have a question. Will the 'box' be subject
to radiative cooling?

That is, will it be outside and subject to exposure
to the night sky? I believe this is your *worst case*
with regards to condensation. Any 'heat' genned by the
components can be used to keep the temp above the
dew point and avoid condensation.
