Whats the difference between the 'N' vs 'K' 280AH cells from Amy?

Havent been on the forum much lately, summer projects have taken precedence (~1850 yards of fill dirt to level out back yard, sprinkler system and fence) but I'm starting the research phase of adding on to my monster sized BYD bank and I noticed Amy has two types of cells and am wondering what the difference is?

This might be old news but a forum search didnt bring up anything relevant.

Thanks!

Seems like EVE just keeps cranking out new revisions of the 280's.

The K is supposed to be rated at 6000 cycles if you thread the needle to set them up as EVE tests them.
The dimensions on the K are slightly different.
It has also been noted that the cycle life depends on doing .5C instead of 1C as with previous specs.

I have attached the spec sheet for both.

Thanks! Much appreciated. Of course now I'm looking at the new 304AHs too. A bit more capacity in the same space.....

I saw a video about the 304's .... I think it was off grid garage. They tested very well and he managed to get his hands on some that were US stock.

They are just a smidge taller than the 280's
