Do you still have Q50 batteries available and if you do could you pm me a cost? I have a few clients one of them with 3 in his house. Just about every other one I had on the field the battery has crapped out about 1 month after the 1 year warranty. When I called Nevo and asked they said they don't carry parts anymore just whole refurb remotes. I asked for a potential parts supplier that might carry the battery and the guy said "well they were built in China so I might start looking there" great help these guys are.
