Screenshot_20210816-201507_AliExpress.jpgi did contact the seller. She said it is for a lot of 4 at that price point, on sale. Something to look at. Maybe test.

Strongly suspect used cells.

They don't have a great reputation. I have an order with them and should get it in a few weeks tops and I'll add my findings to the thread on that seller.

I'd be curious to buy a set though for my sump pump. Perhaps I should. Not a big risk.

My first battery order of four 280ah. They capacity tested at 243 aH! Stay clear.
We would need to see data, including your top balance procedure, in order to take this seriously.

Some folks are claiming they are receiving good cells from them so the bad reviews need to be fully transparent to prove the issue.

I charged them with a ZKETECH Model ECB-A40L to 3.65 V at 20A. Allowed them to rest 1 hr. I discharged them to 2.5V at 20A. I then used the little $50 load tester at 15A discharge with the same results.

All one has to do is research LiitoKala or Sanben, like I, unfortunately didn’t do. Glad I found Amy and Hayley.

Individually, and all of your cells?

Or did you do this as a pack and let the bms disconnect?

Because it's surprisingly easy to get a low ah measurement.

Eh.

I'd have to see a lot more data before accepting it. Especially if you used the tester itself to trigger the shutoff. There's usually voltage drop on those wires.
Why would you question me, after posting this above...

“Strongly suspect used cells. They don't have a great reputation.”

ZKETECH 40’s have 4 wires. I also use meters of all kinds every day. Voltages, charge and discharge currents were verified. This may be my first time installing a 20kw solar system and 112 kWh battery bank on my home, but definitely not the most challenging project I’ve accomplished.

Because your statements have no data associated with them, photos, logs, etc.

I'm not saying you're lying, but I can't assume that you're not either. Questioning it is step one of coming to a conclusion.
Don't take any offense to it. You know what you got from them.

I don't trust this seller at all, and will never buy anything else from them now that I know about better vendors.

Plenty have posted lots of proof of junk.
However. Some folks claim full rated capacity and good condition cells from them too.

In a couple days mine will be here as well.

I’ve sent pictures to the two sheisters, Sanben and LiitoKala. It’s the same story with both of them. “Swelling is normal, we tested and matched, we provide new grade a cells, send us pictures, try testing several times, your equipment isn’t calibrated, we need 12 hour video, bla,bla, bla. I’d go to church if I wanted to deal with liars, cheaters, hypocrites and get my pockets emptied. If you buy from them, be prepared. Hey, I almost forgot, they did send me a pic of their test data. Good customer service is hard to find nowadays, even in the good ole USA.
