Hello

I have 16 280 AMP CATL cells I got them all setup and ready to start my top balance when I noticed green fluid in one of the view windows, see attached picture. How much of a problem is this? What should I worry about here? At this time no fluids are leaking outside the casing, the other 15 batteries are not showing anything in there view windows. The date on the battery is the date I setup the box and was getting ready to individually top balance the batteries, I had the batteries at my house for a couple of months.

Suggested next steps?

Well I guess I need to stop working on this stuff late at night, you are correct once tape was removed suddenly all looked good. Tested your hypothesis on other cells and sure enough they turned green in the same areas. I had not noticed that was the only cell I went over in part with the tape. Well I have some Egg on my face on this one. Thanks for making me take a 2nd look now rather then finding this out as I pulled the battery pack apart. Have a great day.
