They don't work, waste your money Review by Volodymyr

Unfortunately, there is no way to combine 8 cells into one battery, all of them have too different resistance, most likely they have been used for a long time, so, it is impossible to use this product as a battery (Posted on 24-03-23)
Excellent and quality Review by Volodymyr

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).
