@jarodlyles Where can I buy those 7.4 mm long screws? I tried to open my V800 and I think I might have ruined the groves on the screw head. Now, the screw driver just rotates and does not screw in. I am thinking of buying new screws to replace the old ones. Please let me know.

Same problem here: where should I buy the replacement battery? Nothing, really nothing found online… :(

Did you really replaced the battery with a new? Then, why don’t you can answer where to buy a new? Or do you just dismounted it, to show how it can work?
