The Differences Between Battery Series Connection And Parallel Connection

Since the voltage and capacity of a single battery are limited, in practical applications, series and parallel combinations are usually required to obtain higher voltage and capacity so as to meet the actual power supply requirements of the equipment.

Lithium batteries in series: The voltages are added together, while the capacity remains unchanged and the internal resistance increases.

Lithium batteries in parallel: The voltage remains unchanged, the capacities are added together, the internal resistance decreases, and the power supply duration is extended.

For series and parallel connection of lithium batteries: There are both parallel and series combinations in the battery pack, which can increase both the voltage and the capacity.

Series voltage: Single battery cell can be assembled into battery packs with a voltage of 3.7*(N)V according to needs (N: the number of single batteries), such as 7.4V, 11.1V, 22.2V, 36V, 48V and so on.

Parallel capacity: Single batteries with a capacity of 2000mAh can be assembled into battery packs with a capacity of 2*(N)Ah according to needs (N: the number of single batteries), such as 4000mAh, 6000mAh, 8000mAh, 5Ah, 10Ah, 20Ah, 30Ah, 50Ah, 100Ah and so on.
