Michigan Battery percentage unreliable?

[VidyutVahan]

Hi all,

I love my Mach E premium AWD. I have found that battery percentage is sometimes very unreliable. I was pulling out car out of my garage to drive out and percentage suddenly dropped from 89 to 85! Pics below. Anyone else had similar experience? I feel if car thinks temperature is low, it should drop mile range and not percentage! I have also seen that in between drives when car is parked, the battery% drops significantly.

Yes that happens from time to time. It’s probably the BMS being out of calibration. Try letting the SOC go low, like 15%, then charge it to 100%.
