Since the beginning, all three of the batteries for my Phantom 2 Vision are very tightly set in the quad and are extremely difficult to remove. The battery slides in easily until in a position just about where the terminals in the Phantom touch the battery (I don't think the terminals are the issue and merely use this as a frame of reference) or, in another description, the top grey panel just disappears into the machine. This last half inch or so of insertion is very stubborn. Removing the battery requires yanking hard to disengage the two latches. At that point I have to dig my fingernails into the small gap and yank like crazy to pull it free. There is no feeling of two pieces impacting one another. I have looked at the batteries and there is no sign of rubbing or scratching. I used highlighters to mark the battery's surface (water soluble and easily washed off) and looked for places where the ink had been rubbed off from contact--nothing. It feels like simple plastic on plastic friction, but I cannot see any scuff marks that indicate where two surfaces are in such tight contact. Perhaps a simple filing of a burr would fix the problem but only if I can track it down. Has anyone had similar issues?
