Ordered 34 of these bad boys from Dongguan Lighting on 2020-02-24.
Delivered to my door, in Portugal, on 2020-04-02.
The bad:
I was very unimpressed with their physical appearance. 7 had minor external damage, and almost all arrived "dirty".
Rain Zeng said that it had to be damage from the transportation. Thought that doesn't explain their "dirt".
Cells straight out of the box:
The good:
I've been running them for 1 month, in a 16S2P configuration, and they are performing very, very well.
I had some initial trouble due to poor tightening of the busbars (my fault), but ever since I've been able to squeeze 28kWh in and out of them.
I coupled them with the tremendously expansive Batrium but the amount of configuration it allows and the seamless integration it has with my Victron ecosystems made it worth every penny.
Am considering expanding to 64 cells, therefore buying another 32, probably from Dongguan Lighting, if they can assure me a (much) batter packaging.

I purchased my first 8 cells from Dongguan after Rui did, end of April. I have just received them now, after "only" 30-ish days of transit. I also live in Portugal. I'm impressed with the packaging Rain did, maybe he learned from Rui's feedback - mine arrived safe and sound and perfect to the naked eye. I didn't test them yet, only measured voltage, all near 3.34V.
Will post later, but I don't have reason so far to believe they will not rise to expectation.

Today my batteries arrived.
16 X 280Ah
I've ordered and paid them 21-05.
Today 06-06, about 17 days.
Transport took "long" (normally 5-8 days) now 13 days.
Post Corona delays ..
Some pictures
Batteries look good.
I like the protection on the terminators.
No protective corners, the boxes look like they could have used it, pretty banged up.
Voltage all at 3.30, just to be sure I hooked them together as one massive 4480A @3.30 volt.
Tomorrow I can check the size of my molds for pouring copper, if my measurements where correct.
After this, melting copper and making setup!
I payed under 75 USD + 17.50 for DDP to Thailand.
So far, so good ?

As far as I know, same company.
If not, good copy cat
And should make new thread for this seller.
But that's a lot of different sellers if we do them all.
Anyway, look like the same factory, same as the others, the batteries.
For busbars, I can't remember seeing pictures from other buyers.
The white foam was so thick, they could have dropped it from 3 meters without getting into trouble / possible damage.
Outside carton just got banged up.
I asked because packaging was different from Lighting.Dongguan Belifine Battery Co.,ltd. - LiFePO4 Battery, Lithium Ion Battery Cell

The shipping tends to be a bit slower than Xuba, that's probably why. I ordered the same cells as another member here the same day (28.4.). I ordered from Dongguan, he ordered from Xuba. We're both in Europe, both got rail/boat slow shipping, DDP. His cells arrived Friday (37 days after his order). My Dongguan ones don't even register their DPD tracking number as of today (41 days and counting). This means they either haven't reached Europe/haven't cleared customs. ?
Xuba also provides the tracking number and such beforehand. With Dongguan I had to repeatedly contact Tim Yau before he sent it to me. It took him 2-3 weeks to get me the number. You get what you pay for in this respect: Extra $40 = better and friendlier service, quicker response via chat, quicker shipping from Xuba.

Thats good feedback!
In my case, They are $8 a cell cheap, plus $40 shipping. so thats $100 USD for 8 cells. Which is pretty significant. So I guess is Billion we go...

Mine from Dongguan Lightning have other busbars but i like them, pure copper and 2 millimeters thick
Hey I don't think you can conflate rail/boat as one thing since one goes through Russia which has considerable lockdown controls in place right now not to mention there's only 1 rail so it's totally FIFO operation and surely there's lots of backlog post Wuhan flu, whereas shipping by sea is a parallel operation (lots of space for lots of boats).
Too many variables I think to pin it on 1 company being more efficient than another. If the shipping method were identical then you may have a point there...
I think they may be different companies, just both are located in "Dongguan."Dongguan Belifine Battery Co.,ltd. - LiFePO4 Battery, Lithium Ion Battery Cell

You're right, I checked with him and his did arrive by sea. Hope it at least arrives this month at this point now that I think about this.
Does the size of the bolt hole in those bus bars concern anyone? The hole seems a bit large to me. I would want the hole to be closer to the size of the bolt.
So much great information here that I almost hate to ask this... where did you get the box? I've tried to find it by what I can read off the label without any luck. I also would be curious if you could tell me the dimensions of the exterior base as I have a location that I intend to install my cells but that wouldn't be a common dimension given in the advertising...
Thanks for any help!

The battery terminals are aluminum. Won't copper against aluminum result in serious galvanic corrosion over time?

Yes, I remember that discussion and since this is about the same subject I will respond in that thread here.
Mixing cells in parallel string.
I have now 48 X 152Ah lifepo4. In 2 -4 weeks I'll be ordering 2 extra. ATM the 152AH seems to be "sold out". As result I'll take 2 x 120Ah. Same manufacturer, same height (!!) But how to make as set? I'm not sure if location matters. 3 * 152 in the center, and 1 X 120 on each side? Or...diysolarforum.com
I am not the thread police but I have seen comments that the moderators would prefer long threads not be cluttered up with irrelevant comments. The topic of this thread is Donguan Lighting 280Ahr cells. Since the cells you want to talk about are 120 and 150 Ahr cells I am not going to clutter up this thread.
