I have 130 used murata VTC5D for a large battery pack, 20s 6p for approx 60-70A peak. Cells are from 2018, 2019 and 2020 and measure near new.
However the datasheet for these cells specifically states not to mix different batches (let alone years) in the same pack.
Has anyone come across issues with changing specs over the years, or is it unlikely to be an issue?
Is it best to keep individual parallel groups to the same manufacture batch where possible, or just mix and match randomly?
