How to buy cells

[lupo]

I justed orded 120AH cells from https://www.aliexpress.com/store/5403069 and I quite happy with them. took around 7 days, packaging was very good and the have warehouses around the world, so you do not have to deal with taxes and customs. for your 7500 Wh requirements 280Ah cells would be ok I guess.

Do they come with the test reports? Because literally, they day after I ordered, they were manufactured and the test reports sent.
Grade A from Eve means it can't be more than 5 months old (that's why there were a lot of commodity cells).
I'd be very interested in grade A Lishen.

I can get Ganfeng 277ah cells that test 285ah to 290ah that are all from the same batch manufactured on 5-30-21 and have a factory test report of a random sampling of the cells from that batch.

I can also get Keheng 280ah cells that test 286ah to 290ah, right from the factory, that are matched and batched in groups of 16 at the factory and come with the factory test report of the exact cells shipped to you.

The Lishen I get are true grade A cells, but they are on backorder and I have a ton of orders waiting to be filled.

Any word on the Lishen 280Ah cells?

Let us know how they work out when you get them.
A random sampling of a batch if done properly is a perfectly legitimate way of testing.

I bought CATL302Ah from Dongguan lightning on Alibaba yesterday, and I contacted Hayley : https://shandian.en.alibaba.com/pro...pm=a2700.icbuShop.prewdfa4cf.5.6e6e1c399hzYz4. She showed me the test data of their own battery capacity (I believe they tested it by themselves, because no other supplier provided it). And she is very patient to solve all my problems. I think their service is very good!

Do you know how long the wait will be?

Do you know how long the wait will be?

Somewhere between 5-8 weeks was the number I heard.

When did you order them? Please tell us how they test out.

Sadly, today I disputed charges made by @Michael B Caro for cells I ordered from him. For anyone interested in why I had to do this, the story can be seen here:

Beware @Michael B Caro

Sadly, today I disputed the charge of $1,285.92 made to @Michael B Caro for battery cells. The purpose of this post is to completely and accurately reflect my experience of trying to buy cells from forum member Michael B Caro, so that others might know what to expect. We have only interacted...

It has been sad watching this site lately. It seems like the scams have gotten out of control and Michael B Caro got caught up in the middle of it.
When I bought 66 Eve 280Ah cells, over one year ago I was a little disappointed when a few cells didn't test for full capacity.

But after seeing the crap people have been getting lately, I feel pretty good about my purchase. I paid $100 each including shipping.

The price has gone up and quality has gone down from what I see.

I hope you find a solution you are happy with.
