Battery build issue

I did! There is a micro mark in the black plastic and same in white. Reworded everything all it lights up. ?
Now to charge them up and install.

If you have everything wired correctly, you will want to check the BMS thoroughly to make sure it's functioning properly. Especially the high and low voltage disconnects.

I don't follow. Do you mean the black terminal was marked as positive? I don't see any markings on the cells. If it's there it must be tiny.

I am attaching a photo of my EVE cells and as you can see the polarity is clearly marked.

Did the black end up being the positive?

Yes ?

Yes ?

We all live and learn ..... glad you got it right.

I'm kinda impressed with the Overkill Solar BMS if that didn't let the smoke out of it. As Gazoo said, I do some really thorough testing on it to make sure it's OK.
