Ok so I found a li (lithium Ion) battery up on Flag line access/flagline today (9/20/2011). I thought it was probably a battery for someones light system, but it appears this is mostly a batter for a radio, possibly from Vertex?. The model # is FNB-V68LI and it's about 3/4"x3"x 6" and flat black, if you think it"s yours post a reply here with contact info and I can get it back to you if you are local to Bend.
