Lithium batteries in series and parallel, the difference between batteries in series and parallel
Lithium battery series and parallel definition
Due to the limited voltage and capacity of the single battery, in actual use, a series-parallel combination is required to obtain a higher voltage and capacity to meet the actual power supply requirements of the device.
Lithium batteries are connected in series: the voltages are added, the capacity remains unchanged, and the internal resistance increases.
Parallel connection of lithium batteries: the voltage remains unchanged, the capacity is added, the internal resistance is reduced, and the power supply time is extended.
Lithium batteries in series and parallel: There are both parallel and series combinations in the middle of the battery pack, which increases the voltage and capacity.
Series voltage: 3.7V single cells can be assembled into a battery pack with a voltage of 3.7*(N)V as required (N: the number of single cells)
Such as 7.4V, 12V, 24V, 36V, 48V, 60V, 72V, etc.
Parallel capacity: 2000mAh single battery can be assembled into a battery pack with a capacity of 2*(N)Ah as required (N: the number of single cells)
Such as 4000mAh, 6000mAh, 8000mAh, 5Ah, 10Ah, 20Ah, 30Ah, 50Ah, 100Ah, etc.
