It might force BMS to balance harder/faster.
BMS only sees cellpair voltages. It takes that data to balance them.
Do not baby the battery. I hope you already noticed that doesn't help.
Voltage delta should get smaller over weeks. Also if new cells are more degraded
then they will be depleted earlier. Therefore pack will never get balanced.
If new cells are in better health all other cells will run out of juice earlier.
My battery is in very good health. Voltage delta at full charge is less than 10mV.
When pack is really empty delta is as high as 400mV.https://goo.gl/photos/xxzQQZgzxPtXbxPV9
