Hey guys. ****I am posting this because even though I put it in the other thread, it keeps getting discussed so I am posting it here for all to see and anyone that doesn't see the difference, you're on your own. It's obvious to my 3 year old. So I went to Drone's Plus yesterday to ask my friend who is their head engineer, an authorized DJI re-seller and repair shop and forgetting about the wiggling of the battery, he instantly pointed out why one battery looks brighter than the other. It is super obvious and I'm surprised myself, or nobody else can see it. I took pics this time so you can zoom in if you have to. *EDIT I figured out how to post it zoomed in a little. If you can't see it on this post, you are either on a phone or need glasses or new glasses. I recommend looking on a computer screen. First a "good" and "bright" battery right next to each other. Now each battery closer up and look at the plastic covering the bats. The one with the #2 on it, has a matte finish which evenly distibutes the light from the underneath LED and the other one is just a clear plastic which is presumably cheaper but since we now know it's not a quality control issue, can we stop talking about it? Here is the "good" battery close up. I suggest if you can't see it zoom in. It's painfully obvious. Now, I'm going to post the "bright" battery right below it and compare the different plastic covering the LEDs. You see the one above has a matte finish and if you look at your own non-bright batteries, you will see that it looks like the one below. It would almost be like if you put a piece of clear plastic over your LED TV rather than the matte finish of your TV which would make the picture look like a bunch of LED backlights (assuming you don't have an OLED. So click on the image and zoom in if you have bad eyes and cant see it. Bright one. Now with anyone with half decent eyes, you should be able to see the difference here without zooming in. You see how you can SEE THE LEDs as opposed tothe one above. It's ONLY A DIFFERENCE of material covering the LEDs. That's it, nothing more. End of story. Nothing more to talk about as it pertains to brightness. They changed the material either on a production run, for good, or whatever, but it is not a quality control issue, it's just a different plastic. It's even easier to see live so if you have one that is smooth and one that isn't, go have a look. You can literally see how it's not uniform now because you can see the LEDs. Don't know how many other ways to say it but that is it folks. Let's move on from the lights??? Please!
