Battery balancing, also known as cell equalization, is the process of ensuring that all cells in a battery are receiving the same amount of charge. This is important because if one cell is receiving more charge than the others, it can cause the battery to become unbalanced, which can lead to reduced performance and a shorter lifespan.

What I describe below is how I''ve restored the batteries. Use caution. If your battery is at 0.5V/cell, its internal resistance is far higher than if it has only fallen to 1.0V/cell, and both of these cases have internal resistances far higher still than a LiPo at 1.5V/cell. Again, it seems to me that the relationship is *not* linear.
