Comprehensive Guide to 7.4 V Battery Features
7.4V lithium batteries provide a nominal voltage of 7.4V, making them ideal for devices that require a stable and reliable power
Part 1. What is a 7.4 V battery? A 7.4V battery is a rechargeable lithium-based power source, typically configured as a 2-cell (2S) lithium polymer (LiPo) or lithium-ion (Li-ion) pack, with each cell providing a nominal voltage of 3.7V, totaling 7.4V when combined in series.
A 7.4V LiPo battery, also known as a 2S LiPo battery or a 7.4V LiPo battery pack, is a type of lithium polymer battery. The “7.4V” part of the name refers to the voltage, which is a combination of the individual cells inside the battery. Each cell in a LiPo battery typically has a nominal voltage of 3.7V.
A 7.4V Li-ion battery is also a rechargeable battery that uses lithium-ion chemistry. Li-ion batteries are similar to LiPo in voltage and capacity but have a more rigid, cylindrical shape. The 7.4V nominal voltage is typically achieved by connecting two 3.7V Li-ion cells in series.
As mentioned earlier, a 7.4V LiPo battery pack consists of two cells connected in series. Each cell has a nominal voltage of 3.7V, adding up to a total of 7.4V. This 2-cell configuration is often referred to as “2S”. The “S” stands for series, indicating how the cells are connected. Part 3. Capacity
