Lithium battery series and parallel: There are both parallel and series combinations in the middle of the lithium battery pack, which increases the voltage and capacity. Lithium battery series voltage: 3.7 V cells can be assembled into a battery pack with a 3.7* (N) V (N: number of cells) as needed. Such as 7.4V, 12V, 24V, 36V, 48V, 60V, 72V, etc.
Do not let lithium batteries with different voltages in series. Due to the problem of consistency of lithium batteries, they are grouped in series under the same system (such as ternary or lithium iron), and they also need to be selected with the same voltage, internal resistance, and capacity.
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 ability to meet the existing power supply requirements of the equipment. Lithium batteries in series: the voltage is added, the capacity remains unchanged, and the internal resistance increases.
) First connect in series according to the capacity of the lithium battery cell, such as 1/3 of the capacity of the entire group, and finally connect in parallel, which reduces the probability of failure of the large-capacity lithium battery module; first connect in series and then it is of great help to the consistency of the lithium battery pack.
Connecting lithium-ion batteries in parallel or series is more complex than merely linking circuits in series or parallel. Ensuring the safety of both the batteries and the person handling them requires careful consideration of several crucial factors.
When charging in series, if the voltage of a single lithium battery reaches the overcharge protection voltage, the battery management system will cut off the entire series charging circuit and stop charging to prevent the single battery from being overcharged, which will cause other lithium batteries to be unable to be fully charged.
Today we will share with you the voltage difference between the cells of a battery pack. Actually, the difference within a certain range is acceptable, usually within 0.05V for static voltage and within 0.1V for dynamic voltage. Static voltage is when a battery is resting, and dynamic is when a battery is in use.

Voltage imbalances can occur more easily in series configurations, as any small difference in cell capacity or state of charge (SoC) gets magnified across the series string. These imbalances can lead to under-utilization of capacity and accelerate degradation as cells are cycled at different depths, leading to varied states of health.

However, parallel connections often provide longer runtime by increasing total capacity (Ah). For instance, two 12V, 100Ah batteries in parallel result in 200Ah, which can reduce the depth of discharge (DoD) and potentially extend battery life, with lithium-ion batteries achieving up to 2,000 cycles at 50% DoD compared to 500 cycles at 80% DoD.
For example, a 12V lead-acid battery has a voltage range of approximately 10.5V (fully discharged) to 12.7V (fully charged). In contrast, a 12V lithium-ion battery has a voltage range of around 10V (fully discharged) to 12.6V (fully charged). Part 3. What is the state of charge (SoC) in rechargeable batteries?
