Active cell balancing is a technique used to maintain the performance and longevity of LiFePO4 battery packs. It involves redistributing excess charge from the more charged cells to the less charged cells, which results in better runtime by increasing the amount of usable charge in the battery stack. This method uses specialized circuits and components to transfer energy between cells without dissipating it as heat. Active balancing is more complex and more expensive, but it offers higher energy efficiency and faster balancing because of the higher current. 

Passive balancing, on the other hand, involves dissipating excess charge from the more charged cells as heat through external resistors. This method is relatively simple and cost-effective, but it can be less efficient as the energy is wasted as heat. Passive balancing is typically used in smaller battery systems or when energy efficiency is not a primary concern.

In summary, active cell balancing is a more efficient and faster method of balancing LiFePO4 cells, which is crucial for maintaining optimal battery performance and longevity in larger or more sophisticated battery systems.
