Brand new EVE (Grade A) LF280k from NKON arrived (made August 2022)

SolaroSsaurius · Nov 18, 2022

Just received 8 of these cells, looking quite nice, and extremely well packaged.

Have not tested anything, they all show 3.26v - my old meter has only 2 decimal places .

Production date is August this year.

Just for the looks, what do you think of them?

Notice that the upper half has the correct dents to allow the terminals

Your batteries look great to me. I hope you continue to post the results of your testing and build progress. Best wishes for a smooth and successful build!

Very similar to the ones I got from the 18650 Battery Store. Busbars didn't have the wrapping though.

Nice!
Who is NKON? LInk to the site?
What is the total price for each cell?
Looking forward to the test result.
Thanks!

SolaroSsaurius · Nov 20, 2022

I paid 183.55€ each, plus a total of 47.81€ for shipping, which will equate to (for 8 units) around 190€each.

They always sell the next "Grade A" shipment even before they receive! it.

Ok buddy get a ZKE 40 or a fan tester and capacity these them, let us know the AH and WH of each cell

Delphinus · Nov 21, 2022

Did you test your cells and confirm that they are grade A? They look nice I'm about to buy some from them but ask for the test summary and still got no answer.

i agree on the testing, but these guys really do sell grade a cells.
been around , and are the local seller of choice for ev cells.
they are pretty high priced on their ev grade cells though, which is why i havent bought cells from them.

as of recently they have begun selling b grades, bit are very open on that, and no qr code nonesense

Because they also sell B grade I'm a bit worry the cells are for a project to a client so wont use low grade since is our reputation and warranty.

just drive to their store, its near eindhoven,.

also the b grade they sell, have b qr code on them

I do not think that EVE will weld on EVE designed terminals on the rejected cell that did not pass the test, EVE will put 'B' on the QR code for one that fails the test.

I"m more curious on how the LF280K just to compare.

Me too, what I want to buy are the LF280K but they will be out of stock for almost 2 months and I can't wait that long so will test the 105Ah and later the 230 or the 280Ah.

Alkaline · Nov 21, 2022

I want to see if the 280K test to over 280AH, or they are all under 280AH but have over 900WH. If so then my Luyuan cells are fine and this is just how all 280K are.

Have not a tester yet .
Waiting for fan tester.

Alkaline · Nov 21, 2022

get the one with v-sense wires if you can, its a little more but should have better results: https://www.amazon.com/150W-Electronic-Adjustment-Constant-Discharge/dp/B099226TLF

anxiously waiting for your results so I can compare with mine

Let us know the results, meanwhile I just order 32 x LF105, the LF280K are 45 away, try to test it with high load, 20A or 40A it's nothing for those cells, probably I will use an inverter that can draw at least 100A.

zbynek · Jan 7, 2023

I am also considering NKON. Did you have any chance to run some tests on your cells?

The LF105 are grade A same day production have been using them for the last 22 days with a day cycle without problems.

Next week I will receive the LF280K and let you know if they are also grade A.

SolaroSsaurius did you test your cells? What did you get?

Hi.
Due to time constraints on my side I was unable to do any cell related testing
