Lithium battery packs are only as strong as their weakest cell.
Whether you're designing a drone battery, an EV pack, or an energy storage system, cell balancing plays a critical role in battery safety, lifespan, and performance.
But many developers and hardware engineers still confuse passive balancing and active balancing, or underestimate how important balancing becomes in multi-cell lithium systems.
In this article, we'll break down:
Why battery balancing matters
