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.

The term balancing comes from the matching of the cells by capacity and voltage, and controlling their voltages through cycling the battery to maintain the balance, or close to equal voltages at Allstate of Charge (SOC) levels. It is important to note that cell balancing happens before and. .
LiFePO4 battery packs ( or any lithium battery packs) have a circuit board with either a balance circuit, protective circuit module (PCM), or battery management circuit (BMS) board that monitor the battery and its cells. .
Passive cell balancing is where the current entering the battery is bled off through resistors. In this scenario, the current enters the battery. .
In LiFePO4 batteries, as soon as the cell with the lowest voltage hits the discharge voltage cut off designated by the BMS or PCM, it will shut down the entire battery. If the cells were unbalanced during discharge, this may. When it comes to equalizing LiFePO4 batteries, the main techniques fall into four categories: passive balancing (using a Battery Management System, or BMS), active balancing, manual balancing (top balancing), and bottom balancing.
