The relationship between voltage and capacity of a lithium battery pack is fundamental to understanding its performance:Voltage and Capacity: Battery capacity (measured in ampere-hours, Ah) is the product of voltage (V) and current (A). Thus, higher voltage can lead to greater energy storage1.Energy Storage: The combination of voltage and capacity defines the total energy a battery can store, with higher voltage allowing for greater power delivery2.State of Charge: Voltage also indicates the state of charge (SoC) of the battery, helping to determine when to recharge or avoid over-discharging3.Energy Delivery: A battery with higher voltage can supply more energy to devices, making it suitable for high-demand applications4.

Cell 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. .
There are several ways this can be achieved. Batteries can be top-balanced or bottom-balanced. They can be actively balanced or. .
Bottom balancing, as you would expect, is pretty much the opposite of top balancing. Bottom balancing is used when getting the absolute most out of each discharge cycle is the most important. .
Top balance is when the cell groups in a battery are balanced during the charging process. There are many applications that are well suited for top balancing, but the best example of such. .
To manually bottom balance a battery pack, you will need access to each individual cell group. Let’s imagine that we have a 3S battery. [pdf]
