Technical FAQs 4

Do you know how to balance a lithium battery pack?

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.

Why do LiFePO4 batteries need a balancing circuit?

Because LiFePO4 cells discharge linearly, maintaining balanced voltages is crucial for full capacity and performance. A BMS or balancing circuit helps ensure all cells charge evenly, preserving battery health and lifespan. If you have any further questions about cell balancing, lithium batteries, or anything else, please feel free to contact us.

When is battery balancing done?

So, balancing is done during the charging phase rather than the discharging phase. Remember balancing wastes a small amount of energy in order to equalize the cell groups in the battery. Balancing also in most cases starts when cell groups begin to be 4.0v or above.

How does battery balancing work?

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.
