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.
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.
You can also place a li-ion balancer in your pack to perform active cell balancing, increasing the lifetime of your battery pack. When you wire an active balancer in your pack, you want to make sure that the balancer matches the series groups that you have in your pack.
Battery cell balancing is important for maintaining the battery pack voltage/SoC level in EVs, laptops, and renewable ESS. Cell balancing ensures that every cell in the battery pack has the same SoC and voltage level. Failure to properly balance cells can result in reduced usable capacity, shortened battery life, and safety hazards.
A battery balancer is a device or circuit designed to equalize the charge levels across multiple cells in a battery pack.
