[RE-wrenches] 2v metal cased cells

[penobscotsolar at midmaine.com]

Jay,
  A couple of things.
  There is a source for the Surrette/Rolls as 2 volt cells in a single
poly enclosure as opposed to the  double, four volt cells. Contact me
off list.
  We have been using these cells for more than 13 years in the  Caribbean
with great results. We do use ventilated battery boxes and do try as
much as possible to recess them at least partially into the ground
(usually limestone, but can be air hammered out)and as much as possible
on the north wall of the building.
