What is the difference between a 3-cell lithium battery and a 6-cell lithium battery?

1, marking method


The 3-cell lithium battery is labeled 11.1V/2200mAh. This is because the three lithium battery cells are connected in series. The voltage of a lithium battery cell is 3.7V. Therefore, the voltage of the 3-cell lithium battery is 3.7×3=11.1V. And its capacity is the capacity of a lithium battery cell.


The 6-cell lithium battery is labeled as 11.1V/4400mAh, because the 6-cell lithium battery adopts a combination of 3 strings and 2 pairs.


2, capacity


When the same voltage is obtained, the capacity of the 6-cell lithium battery is three times that of the 3-cell lithium battery, and the high capacity is the root cause of the stronger battery life of the 6-cell lithium battery than the 3-cell lithium battery.
