I ended up with two sets of two batteries, plus the one that came with the Inspire 1. If anyone (in the US) is having trouble getting batteries, I'm willing to sell two of them. They came from DJI this week and are still in the box. I'll sell at cost ($318 for the pair) and throw in free shipping via UPS Ground from California. I have a credit card merchant account with Authorize.net so I can take a credit card payment. If interested, you can email me at firstname.lastname@example.org. Will -- 23Feb15: Still available.
