CATL 280AH 6000 cycles QR code location

I would not hesitate to order more just note that these have a discharge rate of .5p max and charge rate of .25p so unless you are using them in 12v packs .. use 2x 12v in parallel if you need more amp output and you want to get the 6000cycles .. be gentle like with any cell. otherwise for 24v and 48v these are a great choice.. but again if it makes you feel better and you can get a "properly branded" cell for same price go for those.... see spec sheet attatched..

Yea I'd be curious how these perform under say a 300w load... my tester can only do 144w @ 40a.. The larger test units cost like 2k to pull 100s of watts at low voltages < 5v petty much any cell even junk cells can handle a 40a load ...

Sadly even tho is 185w it can only pull 20a. So i'm limited at around 65w. I'll probably just test a couple cells (7 hours charge from 3.29V they where at arrival and about 15 hours to discharge them to 2.55V) before testing the full 24V pack with a 3.5kw inverter.

Edit - Those are the test of two random cells. From 3.65v to 2.55v at 20a from the start to the end (without lowering current at the end. Just stopping at 2.55v).
In the first one the voltage is high at the start cause i had a bad connection.

From the results ( 295ah ) i'm pretty sure those are CATL 302Ah cells not reaching the rated specs.
Aspect is great tho and the voltage reach 3v at 288ah.
Let's see how they'll hold up.

Just got the same CATL 3.2V 280Ah LiFePO4 Battery Cell from Shenzhen EEL Battery Co., LTD - was shipped from EU stock in Poland.
QR code ended with OUPTA-191 and doesn't track.
 
does someone have a CATL 302 and can compare it to a CATL 280? Dimensions, weight, and capacity tests.

Some say the CATL 280s are really bad 302, others say no they are indeed 280s.

Both 280 and 302 are manufactured. (Same physical dimensions)
There are some sellers who are selling low tested 302's as high performing 280's.
This can usually be figured out by the QR code.
But some are replacing the original QR codes for fake ones. So, it's hard to determine what they really are.
Either way doesn't mean anything to me. As long as I get what I am paying for.
 
but what about the weight is the 280 lighter than the 302? maybe the are using the same casings as the 302 but have less jelly vs the 280

Weight might be different, but it would be a negligible amount. It's less than an 8% gain.

Even if they are 302s testing at 299ah does not constitute very bad.. the 6 iv tested all at 299ah
 
CATL 280Ah datasheet says the model number is CB310.
The CATL 280Ah cells I got from Docan has scratched out QR code but a portion of it is still readable. It says "CB3100000"
Does this mean it is indeed 280Ah and not downgraded 302s?
 
Guess i received mine from the same batch, i ordered them from Docan (Jenny Wu) at end of september.
Same appeareance and QR-Codes.
I tested 7 of 8 so far, and all are in between 294-296AH (0,21mOhm)

do you have a link to the datasheet, which part of it is the CB31, is that the model number of the code of the manufacturer/facility?
 
well at this point i would say this is a better buy then the 280K grade A, I even asked lampard lei on the forums and he stayed silent so gettem while you can!

spec sheet for CATL 310, 302, 280, 271, 240, 228.
I thought there is no such thing as 310Ah cell.
