Hello to the group and good day. I recently received a batch of 3x6 inch cells from a supplier from EBay. I had ordered from this dealer before with good results. After opening the package from the latest batch, at least 4 of the 40 cells were broken beyond repair. Of the remaining cells after tabbing them, there was a wide variation of voltages from 1 cell to the next. The cells also seemed a lot more brittle and fragile than the first batch. By the time I removed the lowest voltage cells and replacing them and not using the broken ones, I didn't have enough cells left to complete the panel. I thought that I should have producing cells if I was going to the bother of mounting them into the panel. The supplier advises that he will replace the cells with the next batch I order but I don't want any more low quality cells.
Is it routine to have this variation in cells from the same supplier? Is there a way to ensure that the cells I order are good quality before ordering and paying for them.
I happily defer to advice from those with more experience than me. Thanks in advance.
