The Why of balancing: To prevent a higher voltage cell being overcharged and going into thermal runaway, toxic corrosive very smelly smoke and intense fire. Not so good.

Some suggest balancing is not needed, perhaps so if one is very diligent about checking cell voltages. But lipo cells change with cycling and age, the risk is not realizing balancing is needed until it is too late.

Some suggest balance charging is slower than a regular charge, not true at least with good balance chargers.

It is almost always a mistake to balance a discharged pack. At best causes more balancing time when charging. At worst abuses cells since they don't like being discharged too far, why take them lower.
