I recently purchased a couple of genuine Open Box batteries for my DJI Mavic Pro from Camrise for $67 each. They had no charge count and worked perfectly. I noticed that compared to the new genuine batteries I purchased last year, the ones from Camrise are a tad bit lighter in color whereas the brand new ones are slightly darker gray in color. The difference may not be apparent in from distance, but in direct light it can be seen (will post a couple of comparison pictures later today). Should I be concerned?
