One of the reasons is that batteries are advertising things like "10,000" cycles if you only discharge 50% and "2,000" cycles if you discharge 100% and "4,000 cycles" if you discharge 80%. Which fits with how most battery chemistries work - if you veer away from the top and bottom, you don''t stress the chemistry so much and it "lasts longer". Or at least that is

Contributed Commentary by Anton Beck, Battery Product Manager, Epec When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
In lithium batteries, maintaining balance is crucial because it allows for the most efficient use of the battery's total capacity. It also prolongs the battery's lifespan by preventing overcharging or over-discharging of individual cells.
Number of cells: The balancing system becomes more complex with the number of cells in the battery pack. Balancing method: Choose active and passive balancing techniques based on the application requirements. Balancing current: Determine the appropriate balancing current to achieve efficient equalization without compromising safety.
Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
