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.
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.
The experimental results of four Li-ion cells: (a) SoC, (b) current, (c) Switching signals, (d) SoP, and (e) terminal Voltage. This work presents a new active cell balancing algorithm for Li-ion battery cells based on DSoP and CSoP as the balancing criteria.
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.
