These batteries come from battery packs in which welding errors have been found. The batteries have never been charged or discharged.

The cells we offer have:
- Minimal damage to cell
- Never charged during production (from the box) (each cell is tested)
- Resistance is according to datasheet, never worse (every cell is tested)

around 5% have slightly rust below the wrap, see the last photo for an idea

Great cells Review by Matyas
I have ordered 40 cells all withing 0.01 voltage range. There were some bigger bits of copper strips spot welded on there but a couple bits and minutes with a dremel and it's off. (Posted on 22-02-24)
perfect uniform voltage Review by voltzuk
purchased 52 cells to build a 48v 12ah ebike battery with 60a draw. all cells measured at 3.53v with very minimal spot welds at each end. some cells looked brand new. A++ yet again NKON. (Posted on 29-09-23)
30T Review by Antony

You help me decide to buy these batteries! (Posted on 26-07-23)
Superb cells Review by Goldenbunip
Used these cells repeatedly. I just haven’t found anything that compares with its capacity and huge current for such a great price.
Latest pack is a 21AH@72v (140 cells). Happily pulls +80 Amps continuous (the limit of my controller not the cells/bms) with very l little voltage drop whilst staying cool <30c.
I’m on my 4th order of these from NKON, all arrived to the uk within a week, every cell working.
They do have some tab material left on them, but it’s easily to scrape/pull off the big bits and spot welded through the little bits. (Posted on 21-02-23)
