Hey all,
This is my first solar/battery project, and I suppose I'll document my experiences here. I ordered 4 280Ah EVE cells from Basen in march. They got back to me about a week later and said that they were actually out of EVE cells but could replace them with CATL 271Ah cells. I accepted this, mostly because I had taken about a week myself between her drafting the order and me paying for it (I had another opportunity arise and then disappear..), and the prices were suddenly going up and things were getting harder to find, so it still seemed like the best deal I could find.
I received the package today. The packaging was awesome - basically pure padding around each cell - and they included the extra bus bars I requested as well. The cells look good with no dents or bulging that I can tell. There are some scratches on the terminals, but not enough to concern me.
Cell voltages were 3.274, 3.26, 3.275, and 3.272. Should I be concerned about the 3.26?
I still have to capacity test, which I know will be the next big proof whether this was a good deal or not. Unfortunately, I won't have a full day in town to do this until the week after next, but that is apparently within the 'conflict resolution'/refund period, which is 15 days for Basen and 30 days for Alibaba.
The biggest issue thus far is that one of the cell's terminals has holes drilled, but the holes completely lack threading. With another cell, one if its terminal's threadings is wonky and I can only get the bolt in probably a mm or so. The rest of the terminals appear to be straight and fine.
I'm curious how you all think I should resolve this, what I should expect from Basen as compensation, and how I should communicate with them about it. Should I ask for at least a replacement cell? or a partial refund?
In terms of fixes, I don't have any connections equipment, shop, or person wise who could add the threading. Should I just get copper rods that fit the unthreaded terminals as tightly as possible, and secure them the best I can? And on the other cell's poorly threaded terminal, just secure the stud as well as possible?
I attached a photo of all four cells, and photos of the threadless terminals and the height of a stud in the poorly threaded terminal.
