What Is Lithium-Ion Cell Balancing?How to Balance Lithium BatteriesWhat Is Top Balancing?What Is Bottom Balancing?How to Bottom Balance A Lithium Battery PackHow to Top Balance A Lithium Battery PackCell balancing is the act of making sure all cells in a battery are at the same voltage. When building a lithium-ion battery, the process involves connecting many cells together to form a singular power source. In ideal circumstances, brand-new cells will all be at the same voltage level. This, however, is not always the case. Also, not everyone is...See more on cellsaviors Wikipedia

OverviewRationaleTechnologyFurther reading
The individual cells in a battery pack naturally have somewhat different capacities, and so, over the course of charge and discharge cycles, may be at a different state of charge (SOC). Variations in capacity are due to manufacturing variances, assembly variances (e.g., cells from one production run mixed with others), cell aging, impurities, or environmental exposure (e.g., some cells may be subject to additional heat from nearby sources like motors, electronics, etc.), and can be exacerbated by the cumulative eff
