I've noticed in these absurdly warm PNW days my voltage on the JK smart bms app is not correct on the cell level. It will show cells off by up to 13mv, yet when I manually probe them they are all within 1-2mv (using a medium-high end multimeter). All will read say, 3.331, but the BMS will say 3.325 to 3.338
When it cools down a bit overnight it seems to get a little less sloppy to +-6mv.
Also worth noting, i've probed on the cells themselfs, and at the connector to the BMS. I will disconnect the cable strand, probe the entire line to get 3.331 aross 10 cells, then plug it in to see the BMS app being off. Has anyone else seen this before?
