Wow! Inconsistent battery readings!

Hey guys, see attached. Has anyone ever seen this before? I was getting a low battery warning when my controller was still showing 35%. By the time I could get another camera, the readout was at 28% but notice my settings, I'm not supposed to get a low battery warning until 20%.

I also looked at my cells and they all were evenly matched, so it did not appear I had a bad cell.

As you can see the battery has been cycled over 50 times, so I know it's getting a little bit long in the tooth. Any thoughts on this would be welcome, but in the meantime I'm grounding this battery.

As a footnote, this drone hits 5 years for me on this Father's Day coming up. So it's been a good and reliable drone for me now for a long time.

I have had one rupture (i.e. a crack appear in the case due to swelling) after 35 charge cycles. I don't think the batteries are all that good

Agreed. I've heard that users have hit 100+ with these batteries, but I've never come close! And I try to take care off them with proper charging, not totally draining them, trying to leave them stores at/around 50%, etc...

I have had several that have done over 100 and over multiple years. It seem that they are very variable in quality as I dont vary how I treat them. Some are very good and some are crap.
