Active balancing is a cell management technique that moves charge from higher-voltage cells to lower-voltage cells, keeping every cell in the pack at a similar state of charge instead of simply shedding excess energy as heat. So your battery won't get hot as soon as you start using it, like before.

At a continuous 3A rate, this balancing is strong enough to correct cell drift during normal use and to support higher, safer charge currents.

Practically, active balancing means you retain more usable capacity over the life of the battery pack, accept faster and fuller charging without hitting early cutoffs, and experience slower capacity fade so the system delivers steady performance year after year.

Without active balancing, individual cells drift to different States of Charge (SoC) over repeated cycles, which means the battery’s usable energy is effectively capped by the weakest cell; that mismatch forces earlier charge or discharge cutoffs, limits safe charge rates, reduces usable capacity, and accelerates overall ageing.

If the balancing switch is on, balancing will begin when the maximum cell voltage differential in the battery pack exceeds this value and will end when it falls below this value.

For example, if you set the balancing start voltage differential to 10mv and the balancing stop voltage differential to 5mV, balancing will begin when the cell voltage differential exceeds 10mV and end when it falls below 5mV.

The recommended balancing start voltage differential is 0.005V for cells over 50Ah, and 0.01V for cells under 50Ah.

When the lowest cell voltage is below the set value of 2000mV, active balancing will not begin, even if the cell voltage differential exceeds the set value. The balancing current represents the continuous current used to discharge the high-voltage battery and charge the low-voltage battery during energy transfer. The maximum balancing current represents the maximum current during energy transfer, which does not exceed 3A.

The difference between 1A, 2A, and 3A active balance lies in the maximum current (amperage) they can use to transfer energy between battery cells.

In essence, a higher amperage rating means the active balancer can correct imbalances more quickly and handle larger cell capacities more effectively. All types use non-dissipative energy transfer methods, meaning they are more efficient and generate less heat compared to passive balancing systems.

1. Cell Overcharge Protection and Recovery
When the voltage of any cell is higher than the set value of the cell overcharge voltage, and the time of duration reaches the cell overcharge delay, the system enters the overcharge protection state, the charging MOS will turn off, and the battery cannot be charged.After the cell overcharge protection, when the voltage of all cells drops below the cell overcharge recovery value, the overcharge protection state is released. It can also be released by discharge.

2. Overall Overcharge Protection and Recovery
When the overall voltage is higher than the overall over-voltage set value, and the time of duration reaches the overall overcharge delay, the system enters the overcharge protection state, turns off the charging MOS, and cannot charge the battery.When the overall voltage drops below the recovery value of the overall over-voltage protection, the overcharge protection state is released, and it can also be released by discharge.
