Just curious what you ended up doing? We also have a TPO roof to install 4 flex panels and looking for idea.... Thanks for any feedback on your solution.

My order (of only 4 Lishen 272 cells) from Exliporc has all been fine. I am capacity testing now, and so far all seems as it should. They also replaced a damaged BMS via express mail for me. This really sucks that they are obviously all over the place in terms of quality. But just wanted to...

I received mine. All perfect so far, exactly as they stated in our discussions. Top balancing now. Sorry you had a bad experience as mine has been 100% positive. The BMS they sent was damaged in shipment and sent a replacement express mail within days.... No complaints so far.

https://exliporc.m.en.alibaba.com/ Also received an email from them the other day they have EVE 280 in stock (3000) for $84. As always I would chat with supplier to get specific pricing and shipping costs.

Yes, actually just received them last week. About 45 days. All was good. Batteries are in perfect physical shape. Date code matches the manufacturing date they sent me prior to ordering. The box and BMS also arrived. Only one issue was the temp sensor was broken off the BMS circuit board...

Based on these threads I am not sure that is correct: https://diysolarforum.com/threads/lishen-272ah-cells-aluminum-case-positive.16458/ https://diysolarforum.com/threads/insulation-material-between-aluminum-case-cells.15388/

Maybe an issue of the 4s bms monitoring multiple cells per lead? Not sure if this could be an issue or not, just throwing it out there.

I went ahead with the order and wanted to let folks know what I ordered and at what cost. 4x 272ah Lishen cells. Matched via voltage, IR, and capacity (will confirm upon receipt, but if their data is false I will ask for refund. So far I have no reason not to believe them and their...

Thanks. I understand they use a meter to test IR. My question is the IR is off from spec and is this a huge deal, or not? Regarding capacity, I asked what method they used and will see what they say. Obviously buying 272ah cells, that is all I expect. There have been various reports of...

I have ordered batteries from a supplier I am not sure is used much here. They stated they would test my 4 cells for voltage, IR, and capacity. Here are the test results I was sent: All seems ok to me. But IR in spec shows .12, and these show .14. Is this an issue, or not a big deal...

Per spec IR should be .12 +/- .05 mOhms

Exliporc on Alibaba is stating they will deliver 4 272ah Lishen cells for $365 with 60 day DDP shipping to the US. The contact, Wendy Leung, has also stated they will capacity test the cells as well as match by voltage and IR. She said they will provide the test data to confirm matched cells...

Thanks! Are the external dimensions of the box listed correctly then? I see it as 245mm high? Or is that the height of the box and the lid is higher? If so, do you know that measurement?

What size studs did you install on the cells to still allow the top to fit on the box? My measurements show it as a pretty tight fit in there, but based on your photos it seems to work fine. I see the height of the cell as 207.5mm, and height of box as 215mm. That's only about 1/4" of room......?
