(2) Sharkk Rechargeable Batteries for GoPro Hero 3 (I believe) $12.oo OBO (or a decent six pack..) Ordered these for my dad's Hero 4 and quickly found out that they were the wrong size. Never opened, never used. Before sending them back, I figured I'd see if anyone local could use them. Bought them for $13.oo for the two off of Amazon.com. Located in South Minneapolis and/or South St. Paul.
