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 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.

Whether you are new to battery building or a seasoned professional, it's totally normal to not know how to balance a lithium battery pack. Most of the time when building a battery, as long as you use a decent BMS, it will balance the pack for you over time. The problem is, this can take a very, very long time.
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.
If you built a lithium-ion battery and its capacity is not what you expect, then you more than likely have a balance issue. While it's true that cells connected in parallel will find their own natural balance, the same is not true for cells wired in series. Battery cells in series have no way of transferring energy between one another.
Not all battery chemistries require balancing, but balancing is essential for lithium-ion batteries and other multi-cell systems where consistent charge across cells is crucial for performance and safety. Q2: How Often Should I Perform Battery Balancing? The frequency depends on the battery type, usage, and the balancing system itself.
In Li-ion batteries which have very low self-discharge and therefore accumulative unbalance per cycle is usually less than 0.1%, bypass current of internal FETs is sufficient to keep the pack continuously balanced.
As told earlier when a battery pack is formed by placing the cells in series it is made sure that all the cells are in same voltage levels. So a fresh battery pack will always have balanced cells. But as the pack is put into use the cells get unbalanced due to the following reasons. SOC Imbalance
Static voltage of lithium battery pack when fully charged
