Ship it to me, and for $190 it will be as good as new. Seriously, what are you willing to pay for the repair including shipping? At $75/hr it will probably take 2 hours plus shipping so you are are going to be at about $190 to get it back. I think you need to fix it yourself or keep the battery pack, throw it in the trash and buy another. That's how you fix Chinese stuff.
Seriously, why be a jerk about it.
