Which side draws more current?

[E-Revonut]

I have noticed that with quality cells the stutter with the MMM can be hard to tell, it can even be hard to tell that there is a loss of performance until the hard cutoff does its job. With time you will learn though and when you see the performance, top speed, drop off it's time to re-charge. Running the packs to the hard cut off is more demanding on the packs and that is likely why you are seeing one pack a little lower. There is most likely one cell that is slightly weaker and causing this.
