Dynamic voltage difference at charging end |
≤300mV |
At an ambient temperature of 25°C, charge at a constant current of 0.5C to a total voltage of (3.5*N) V, then switch to constant voltage and charge until the current is ≤0.05C or higher. The cutoff of the cell is 3.65V. The voltage difference between each battery terminal is not greater than 300mV. |

Dynamic voltage difference at discharge end |
≤300mV |
At an ambient temperature of 25°C, after the battery pack is fully charged (the maximum cell cutoff is 3.65V), it is discharged at a rate of 10h, and the cutoff voltage is 21.6V (2.7*N) or the lowest cell is 2.7V. The voltage difference between each battery terminal is the same. Greater than 300mV |
