Is there a preferred method to break in a new battery pack? I just had my battery pack replaced. The service manager passed on that, in order to successfully balance the battery, what I needed to do is drive the car until depleted to about 10 miles remaining (without charging in the interim), then fully charge it. Do this repeatedly for several weeks. Does this make sense? It sounds unneccessarily stressful on the battery, and I don't see how it aids balancing. I haven't charged since I got the new battery pack home, but looking at the ESS grid, it's all zeros - seems well balanced already. The CAC seems higher than previously but I don't know if the calculation has any carry over from the prior battery pack.
