It's up in the air now. I was seriously thinking about making it into a pusher trailer for my Firefly/Metro, but that was when I thought I had a better battery pack than the one I've got. (It's going to be pushing ~50% more weight, so I figure range is going to suffer by about that much.)
Short term plans are to put the other batteries back in it and just keep using it. It's probably good for at least another year.
Why, you wanna buy it?
Parting it out is probably its ultimate fate.
