Battery balancing is the process of equalizing the charge across individual cells in a battery or individual batteries in battery groups to ensure uniform voltage levels, or state of charge (SOC). This process helps prevent overcharging or undercharging of cells, which can lead to performance degradation, reduced capacity, and shortened battery lifespan.
