Other question: Why are the price of NiMH-cells are so high? 2x AA for 14$ ? I would expect less than 4$ for 2 cells
It means Aliexpress.

There is some problem with my translation, âspeedwayâ means Aliexpress, the coupon code is for Aliexpress stores, the coupon code canât be used on the official website at the moment!

Hi, our batteries are higher quality, absolutely genuine, so the price is higher!
Weâve got a shipment of Grade B JP30. Do you need it?

Hi! What does grade B mean? I need them for a 3S1P battery pack, so mismatching between cells is a problem.

First of all, thank you very much for the honesty. Iâve bought âseller-unannouncedâ B-grade (or at least definitely non-A) batteries in the past, and definitely didnât like the results when I put them through. my tests.
Second, I echo @ebastler question on exactly what B-grade means when compared to the official specs. Less capacity/CDR/life cycles? Higher IR? My use case, like his, also involves serial configurations (albeit only for discharging â at least initially, they will be charged separately), so consistency among different cells is important.
TIA!
Knowing your concerns, I found my boss and asked for the parameter sheetďźItâs perfectly fine for battery packs, donât worry about that!

Class B battery means that the power drop will be faster, for example, 50PL Class A is 10,000 parts per million drop, Class B is 1,000 parts per million drop, you can refer to the screenshot of the table I sent you. 
OK But I canât get the product pages to open. It flashes a picture of batteries for under a second then goes to the error page saying the page canât be found.
The 2 Lii-50A 26650âs were bought from the Liitokala Official Store and where shipped with âYFH Special Standardâ, so shipped/provided by the vendor.
The single Lii-70S was purchased from the liitokala factory flagship store and shipped with the same carrier.
The same shipping company appears to have been used when I bought a couple of 46950 batteries a while back.
I could do so, but it already feels a bit awkward talking about all those stores in a topic specifically for the Vapcell store and posting direct links to stores of their competitors in this topic, would really make me feel awkward⌠
I wouldnât mind posting those links in a different topic, but I canât of the right topic to do so or what kind of topic to create âto post just a couple of random linksâŚâ.
If you know a good place to post them, let me know!

Does that mean with high amps load the voltage drops faster on Class B than Class A? But no difference in cell-to-cell matching, and same max current?
If so I would take 3 already made into a pack if possible. Who do I contact to specify the details (how to weld etc)?
1 Thank
Yes, please just send me a private message with your needs, whether you need a BMS, etc.

Wow, that is a really good/low (AC)IR, with ~ 3,3 milliOhm! That is in the same âterritoryâ as JP40/45D/40PL cells.
Interesting cell that I wasnât aware of yet! 
1 Thank
It would be nice if you posted links for the cells. AE search is not good. Or are they at the Vapcell main site?
