Battery Cell Imbalance: What it Means (+How to

Battery cell balancing brings an out-of-balance battery pack back into balance and actively works to keep it balanced. Cell balancing allows for all the energy in a battery pack to be used and reduces the wear and

Cell Balancing. Why it is Important for Batteries?

With cell balancing, the charging of the battery stops when the voltage of just one cell exceeds 4.2V. Passive cell balancing then discharges the affected cell using a small resistor, and charging then resumes. This process repeats until all cells are balanced to a given mV threshold (balancing to +/- 1mV is not practical).
