A local vendor has EVE 130AH LFP cells. I am contemplating on buying 8 cells for a 24v pack.
But in EVE website they do not list a 130AH version.

Is anyone using EVE 130AH LFP cells ?
Does anyone know it's cycle count ? English version and Chinese version seems to offer different numbers.
 

Helps to read chinese, but it appears the EVE A31 cells are 130Ah.

Yes I had downloaded the A31 spec from above link, according to it there is below text which I don't understand since I cannot read Chinese.

Is there anyone who can understand Chinese that can explain above Chinese text ?

My wishful thinking is that 4500/6000 is for Standard charging and 1500/2000 is for Fast charging.

You can read the Chinese text by using the lens function built into Google translate, but to make it easy for you I did it already. The below is the translation. I would interpret “weeks” as cycles.

No obvious explanation for why the numbers are different in the English version except that a mistake has been made.

Hey I'm glad that someone is getting use out of my efforts to find cell datasheets. (Edit: Disclaimer, All of the datasheets I have posted have been found in the wild, None have been give to me by EVE)

As for why the "English" version is different it is possible that the vendor has edited it to look better. You can tell based on the bad translation. When cycles is translated from English from Chinese you will see weeks or times. If you look at the other official English EVE datasheets in that collection you see it is always translated as cycles. I have found many fake or altered datasheets as i've hunted for them. Notably is the CATL 310Ah datasheet which is an edited CATL 100ah datasheet.

There is another less likely but possible explanation. The A31 datasheet provided is the A31-V1 datasheet. There does exist a A31-V2 and that could be the datasheet you are looking at though I'd find that less likely. The A31-V2 is also a higher capacity cell being 141ah over the 133ah in the latest EVE brochure I have. There are also other versions like the LMFP (Lithium Manganese Iron Phosphate) that I saw at the battery show Europe. Note that it's show wrap is purple instead of Blue (LFP) or Green (NCM).

Lastly the reason that the datasheet is only in Chinese and the reason for it not being on EVE's website is that it is one of their Automotive department produces. EVE USA does not advertise any of these at all. (They've also given me the run around when I have asked about them).
 
As a further follow up EVE Alibaba actually lists the A31-V1 and A31-V2 now and they put it at a cycle life of 2000 cycles

Thank you For Translating.

@zcskywire2, thanks, the English version image I posted is from A31-V1, which I got from the local vendor.
