7.4V lithium polymer batteries have a unique application status among numerous electronic devices. In terms of capacity specifications, there are abundant choices, covering various models ranging from smaller capacities to larger ones. In practical applications, some medium-power handheld devices such as some drone remote controllers may adopt 7.4V lithium polymer batteries. With their moderate voltage and appropriate capacity, they can provide stable and continuous power support for the devices. Compared with 3.7V batteries, they can meet higher power requirements, and compared with batteries of higher voltages, they also have certain advantages in terms of volume and compatibility, occupying an important position in the field of battery selection for electronic products.
7.4V lithium polymer batteries have the advantages of high energy density, high voltage and customizable shapes, and are widely used in the following several fields. In the field of consumer electronics, the high energy density brings long-lasting power to mobile phones, tablets and so on, and the customizable shapes meet the diverse design requirements, making the products thinner, lighter and more beautiful. In the field of medical equipment, the high voltage ensures the stable operation of precision instruments, and the high energy density reduces the charging frequency, guaranteeing the continuous progress of medical examinations. In the industrial field, the high energy density helps unmanned aerial vehicles (UAVs) work for a long time, and the customizable shapes facilitate their installation in narrow spaces and improve the flexibility of operations. In the field of thermal and outdoor products, the high energy density makes heated clothing keep warm for a long time, and the customizable shapes are suitable for different clothing styles. In the toy field, the high energy density prolongs the usage time of toys, and the high voltage enhances the power performance of toys, making playing more enjoyable.
Both 7.4V lithium polymer batteries and 3.7V lithium polymer storage batteries have their own advantages. In terms of voltage, a 7.4V battery is formed by connecting two 3.7V batteries in series and can provide strong power for high-power equipment, while the 3.7V one is suitable for small electronic devices with low power consumption. In terms of energy storage, with the same capacity, the energy of a 7.4V battery is twice that of a 3.7V battery, and it has better performance in long battery life. The 3.7V battery can increase its capacity by being connected in parallel. Regarding charging and safety, due to its higher voltage, the charging management of the 7.4V battery is stricter and the requirements for its protection circuit are higher, while that of the 3.7V battery is relatively simpler. In terms of application scenarios, the 7.4V battery is mostly used in fields with high requirements for voltage, power and battery life, while the 3.7V battery is widely used in ordinary consumer electronics and low-power equipment.
