My I-MIEV has 117k km on the odometer and I have been paying closer attention the the battery voltages lately because I'm wondering when my range is going to start dropping. I became more vigilant recently after I replaced the tires with new Enasaves and noticed a significant change in my RR. I never would have thought that the tread depth of a tire would make a noticeable difference in range, but now I know it to be true.
Anyway, I'm wondering if anyone can comment on my delta V in this pic. The battery is at 9%. Cells 18 and 19 are worrying me.
