- Good cells, I'm happy. Review by Andrii
-
Excellent geometry, identical parameters. I thought they would be worse, since this is grade B. But I was pleasantly surprised. (Posted on 25-10-24)Rating - ok, but no qr-codes Review by Marina

The capacity of the cells fully corresponds to the declared one, but all the holograms are erased and it is not possible to identify them. On one cell the hologram was poorly erased and it was possible to see that the cell was not 315, but 305!Rating

All cells have capacity of 326,7Ah to 327,9Ah testet with 40A internal resistance is0,18 to 0,19mOhms and voltage 3,295V (Posted on 10-10-24)Rating - ok, but no qr-codes Review by Stanislav K.

Same story - all cells are good 3.3 volt all. All prodused at may 2024, but there is no QR-codes at all and no any manufacturer id. (Posted on 29-09-24)Rating - Nice, but... Review by Putin Huilo Ibanoe

B-grade cells are cells usually did not qualify as A-grade by the manufacturer. This may be due to optical imperfections, higher self-discharge, lower capacity and/or higher internal resistance. Unfortunately manufacturers don't tell which aspects or aspects are the reason to mark a a specific cell as B-grade. We have sold several and get seldom negative feedback. We tested several eve B-grade and one had about 2% lower capacity, the other ones we did not find a difference with A-grade cells. We don't advise B-grade for high performance electric vehicles but for home energy storage they will work fine. In case you get one which performs significant less than the others like lower capacity, high self-discharge or fast wear we will replace it. Take care that we don’t put a lot of trust in a simple test of a single cell, if you buy 16 cells and you test them and they are all 6% lower than expected then your test gives to low results. If you buy and test 16 and 15 cells give you 100% and one cells gives 5% lower results then we will replace one. When we buy cells the cells are tested for voltage and internal resistance. Also a couple of every batch are tested for capacity, and if one gives less than 100% capacity we test the whole batch and discard the bad ones or don't buy the batch at all. Lot of seller in china buy B-grade cells, test them, even swap qr-codes and sell the good looking and performing as A-grade cells. We believe our B-grade cells are the same as lot of A-grade cells from China, including the well known resellers there with good reputation. We give regular warranty on these cells (at least 2 year).
