Отличные аккумуляторы Review by Иван
Заказывал здесь в первый раз. Заказал 30 штук, часть с контактами для пайки, часть без. Огорчило, что батареи без контактов маркированы датой 11.2018, а остальные 10.2019.
Аккумуляторы отличные!
I ordered here for the first time. I ordered 30 pieces, part with soldering contacts, part without. It was disappointing that batteries without contacts are marked with the date 11.2018, and the rest 10.2019.
The batteries are great! (Posted on 26-06-20)

Excellent batteries Review by Stanimir
I've tested these batteries with LiitoKala 500s (charger, discharger, tester) with 500mA current. All four tested batteries had capacity over 2700 mAh within 10-20 mAh (declared capacity is 2500 mAh). I'm very pleased with this product and I've ordered another pack of four. (Posted on 04-03-20)

Отличные аккумуляторы по отличной цене. Review by Andrey
Брал 2 раза, первый раз шли 29 дней (не рассчитал что отправка по вторникам), второй заказ 22 дня. В обоих случаях пришли с зарядом 3,52v. и весом 44 гр. Сроки производства, 1 заказ - май.2019 г, 2 заказ - апрель 2019 г. Брал для переделки аккумуляторов в шуруповерты. Показали себя отлично.
I took it 2 times, the first time went 29 days (I did not calculate that it was sent on Tuesdays), the second order was 22 days. In both cases came with a charge of 3.52v. and weighing 44 g. Production terms, 1 order - May 2019, 2 order - April 2019. I took it for converting batteries into screwdrivers. They proved to be excellent. (Posted on 09-12-19)
Отличные батареи 18650 Review by Alexandr

Excellent samsung 18650 batteries, internal resistance of only 10, there will be excellent current efficiency. Fast shipping. Will order order that the dispatch occurs on Tuesday. I recommend the product and the seller. (Posted on 20-11-19)
Good, but date date does not match declared by email. Review by Aliaksandr
I wanted to order 100pcs, but made test order and bought only 20. Order was made 26-08-2019. Received 5-08-2019 in Bialystok, Poland. All batteries has 3.44V, 44g, and impedance ~ 13mOhm. Before i place order seller told that they get fresh batteries produced on May 2019, but in my parcel i get January 2019. In any case, this is better than 2017. In my opinion, these batteries 99% are similar to the original.
I plan to use batteries to build an electric bike. (Posted on 07-09-19)

Dispppointed Review by Amir
I just got my cells and my first impression was not what I expected. The cells were wrapped in a plastic foil and were damaged. To be honest I thought that the cells were salvaged from old laptop batteries when I opened the package. Like I said I expected more from NKON. Even Aliexpress or banggood have better packaging method. (Posted on 07-11-18)
2560 mA to 2610 mA on first charge :) Review by Robert
I have received the batteries in a week. I put them to test charge (drain and recharge at 500mA) and all 4 of them show between 2560 mA to 2610 mA capacity. It is not often that batteries show more than their declared capacites : )
I have not tested them at high drain and charge yet, need to break them in a bit before that. (Posted on 16-05-18)
Perfect! Review by Alexandr
13.01 заказал 10 штук, 9,02 получил
Упаковано отлично, в жесткую коробку с наполнителем, аккумуляторы смотаны пленкой в один ряд, дошло все в целости и сохранности, потестил на зарядном устройстве- емкость соответствует завяленной.
Спасибо за отличный продукт, буду заказывать еще.
13.01 I ordered 10 pieces, 9.02 received
Packed perfectly, in a rigid box with a filler, the batteries are wrapped in film in a single row, it all came in intact and safe, tested on a charger-capacity corresponds to the wilted.
Thanks for the great product, I will order more. (Posted on 16-02-18)

Very good 18650 battery Review by Antonio
I have tried several batteries in my Ecig mods and the Samsung 25R is one of the best batteries I ever owned.

Excellent vendor!! Review by Yogi
Hey, they're Samsung R25's...what more can you say than that they are amazing and affordable? What I'm most impressed about is the level of service that NKON offers! I never have to worry that my batteries aren't packaged correctly, or that they are fakes. If you order more than one they are wrapped in ceramic wrap to ensure that they don't make contact (Big thumbs up for that!!!) (Posted on 25-08-15)

Prima levering, toppie communicatie! Review by BMW325TI
Ik heb ik de cellen nog niet getest i.v.m. tijd.....

Maar ik heb eerder 25R gebruik, prima cellen voor hoge belastingen; alleen als nadeel is de capaciteit ietjes lager vergeleken met andere cellen.

Verder is levering prima! en communicatie met verkoper is zeer goed!
Eerlijke en vriendelijker verkoper, tot gauw.......

Excellent delivery, good communication!
I did ask the cells not yet tested i.v.m. time .....

But I have been using 25R, fine cells for high loads; only if the capacity is a disadvantage ietjes lower compared with other cells.

Further delivery is fine! and communication with seller is very good!
Honest and friendly seller, see you soon ....... (Posted on 22-03-15)
