Ordered 8pcs. Was shipped on 14th Oct with Nova Poshta Global. Arrived at Ukrainian customs on 24th Oct. and stayed on hold for clearence. After receiving I didnt find any sheets inside the box where I can see tested capacity. QR code also did not give me any info. Seems like this cells are counterfeit "A-grade". (Posted on 12-11-24)

Nkon delivery to Ukraine took 2.5 weeks

Didn't notice that the batteries DO NOT have QR codes on them so no way to learn about its origin.

Internal resistance is hit or miss between 0.06 and 0.20 mOm (Posted on 16-08-24)
