Customer Reviews

Almost match declared capacity Review by Sergii
Ordered 8, received 4 marked as 287AH and 4 marked as 282AH. One of last 4 weighted only 5.196 kg (4% lighter than others!) and this one was the weak ring in chain: I've got 266.4 AH for this cell (6.82 KWh in discharge cycle) with 0.3C from 3.512V to 2.85V. All other cells at that time was around ~3.05 (4 marked as 287) and ~3.0 (the other 3 marked as 282). Anyway - it is still good for the price. I could replace the "bad" cell for free, but I won't - disassembling the battery, waiting for replacement and assembling it back is not worth it. I'd probably spend few Euro to buy couple of 26650 cells and balance the pack just attaching them in parallel to the weak one. That's anyway cheaper than A-grade. (Posted on 10-04-23)
Great quality for grade B Review by Jesper
Bought 32 of them in the summer. 2P16S (48v offgrid solar/storage) first charge discharge they all kept the same voltage from start to stop (0,000V difference). on this big 560Ah pack i use one 5A active balancer (max difference measured is 0,026V under load) and now 6 months later they are still perfectly balanced. 28,6kwh battery pack in theory but on a test discharge i got out 29kwh from the package, so they even deliver more (but this is under 0,1-0,2C discharge!)

Highly recommend this cells for energy storage, very good quality! (Posted on 09-12-22)

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).
