Hello EV friends,
nkon.nl seems to be the biggest and i guess best shop for all kinds of cells in Europe.
They also offer much cheaper (in my case 23% cheaper) "reclaimed" cells and describe them like that:
"These batteries come from battery packs in which welding errors have been found. The batteries have been removed and the + and - sides have been sanded. 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)"
So as the price for example of the "samsung 21700 40T clear wrap" of 3,65 € instead of 4,75 € is really attractive and cheap way to get a high power battery pack, i wanted to know you opinions or experiences about these reclaimed cells ?
Do you think the fact that the cell will be heated twice by spotwelding it will influence the life cycles or the performance ?
Or can you think of any other disadvantages i should think of ?
Or is it really just a optical difference ?
And does anyone know why they produce clear wrap cells and why they are cheaper than the colored ones ?
here are the links of the compared cells:

Thanks a lot for your help!
