Received my second shipment of Catyl 302/310ah cells from Basen. Cells were all quite bloated. Almost a 1/4" of space between cells. I top balanced to 3.58 and noticed the cells expanded another 1/8" or more. Went to put them in series for capacity test and couldn't fit the bus bars without canting the cells. Ran capacity test and got 321ah. I was disappointed at getting bloated cells, then delighted at getting great capacity. To top that off, after capacity testing, the cells contracted to almost flat.
So the big question is, to compress while they are almost flat and then charge them and hope they don't blow the pressure relief. Would be compressing with 1/4" aluminum plate like I did with previous non-bloated cells.
