Lishen 270ah-272ah cell group buy.

Solar Enthusiast
Received my batteries today! 20 CATL 305AH from Michael. They all look like no dents and a couple of them have slight bulges (very slight) and the QR and labels are all intact. Over half of them the blue wrapper and black covers are peeling around the edges.

Went through and the voltage reads 3.27 to 3.28 on all of them.

Still waiting for bus bars and nuts.

Congratulations! Are they from EV packs?

@Michael B Caro Just wondering if you can confirm I am on the refund list. I've sent a few PMs and emails and I just want to confirm so I don't have to contribute to your flooded inbox any more! Thanks Michael, sorry for this crappy situation.

I would also like a refund. I’ve posted here before and sent a couple of emails, posting here again for visibility.

I have also asked for a refund via email and PM without response. Posting here too. I already purchased replacements elsewhere. Thanks for setting this up. Sorry it went sideways.

A few days ago I received my order of 16 Keheng 280s from @Michael B Caro . I had them shipped to him first, then to me once he got them, extra shipping at my expense. All told it was about 3.5 months. The boxes were a little beat up, but there was a lot of padding. As you can tell from the pictures, all boxes containing the cells show the terminals were poked through. The inner boxes were large enough that it wasn't just due to tight packaging, but that probably on the trip from China to MIchigan they were handled roughly. None were dented or bloated, thankfully. All were at a voltage of 3.3 except one cell which was 3.2. Not so 'matched and batched' It is now charged to 3.3, so I'm almost ready to do a parallel top balance.

Compared to most here, so far I appear to have gotten lucky.

Finally realizing I should take a good look at the terminals, I see that three cells, all from the same box (I kept them in order during unboxing), have bent terminals. In the attached pics, the cell in the background has normal, perfectly straight terminals. The three in front of that all bend to the left. The tops of the cells feel a little caved in.

Should I proceed as usual? Could these have a higher risk of an internal short? I'd hate to burn down my RV because of them, especially when I paid extra for these cells. I also never got the factory report (which I didn't get, even after asking him again for it).

All input is appreciated.

They are supposed to be getting me that report.

My daughter opened and checked all of the cells quickly before shipping. I just called her and sent her the picture.
She is very sure that she did not ship any cells that looked like that, but she said she seems to remember there was one cell that the stud was not perfectly straight, though not to that degree or she would have have shipped them. So I am not sure if it was further damaged between Michigan and you, or what.
I will show the pics to suppliers other than Keheng, and get their opinion on using a cell with a stud like that. If we need to replace those three, we will, and just have you ship those back to us and we will use them in an application in MI.

Even if I had received cells packaged like that perfectly intact, I would not be happy with the packaging!
What might well have happened is that they were set down upside down with some force. That force would then be transferred to the studs and could be enough to bend them.
I'm not going to speculate where on the journey this occurred, but that's why good packaging is very important.

I always demand packaging like this for any cells we order/send:

Since we upgraded to that, we haven't had any issues with damage in transit (we have previously), even when the boxes look pretty beaten up. With studs you've got to make sure there's a hole in the foam for them.

Sorry, I know this doesn't really help you. Sounds like a crap situation for all involvled!

Can we just exchange the cells now so I'm not perpetually losing sleep over burning down my RV?
