I just had a couple new batteries come in and now not only do I have the LED brightness issue which was just a consistency concern, I now have a concern of safety. All of the new batteries that just came in do not slip in to place like ones I currently have. I can take one finger and push my other batteries in and they snap right in and dont even have a nano-inch of movement. The new batteries, if I don't take extra special care snapping it in, it will have a large gap on the bottom and I am almost certain would fall out mid-flight. I can manage to get it in and hold in place using two hands and making sure it's perfectly flush but even then it has some wiggle movement that my good bats don't have. It seems locked that it wouldn't be a problem but it's not the safest feeling in the world. Now this is on 4 batteries. I remember reading, at least a couple times of people with this issue, but I brushed it off as usual until it happens to you. I called DJI and they told me to make a video of it and send it to them and I did. I might post the vid on YouTube and if I do, I'll post it here later but was wondering if anyone else has experienced this. Anyhow, these are being replaced by DJI so no harm but still, so much strangeness!
