I get very similar results with my C4-12 and the same 30Q button top cells from Richard. Unfortunately, the IR testing feature in this charger is quite inconsistent, at least on some cells. I’ve observed IR as low as 52 and as high as 646 with these cells, and that’s on fully charged cells. If you check it on depleted cells, it’ll be even more inconsistent.
