High Quality Lithium Ion Battery Pack 7.4V 2S1P Batteries With PCM Customization Supported Battery Packs

Description

The High Quality Lithium Ion Battery Pack 7.4V 2S1P Batteries from Long Sing Energy are engineered to deliver consistent performance, compact structure, and dependable safety. This battery pack is based on lithium-ion cell technology, typically using 3.7V cylindrical cells such as 18650 or 21700, depending on the required capacity, size constraints, and discharge rate. In a standard 2S1P configuration, two 3.7V cells are connected in series to achieve a nominal voltage of 7.4V, with a full charge voltage of 8.4V.

To meet different runtime and power requirements, Long Sing Energy supports multiple capacity options for this battery pack, commonly ranging from 2000mAh, 2200mAh, 2500mAh, 2600mAh, up to 3500mAh, depending on the selected cell model. By using high-quality Grade A cells and precise assembly processes, the 7.4V 2S1P Batteries provide stable discharge behavior and long cycle life, even in demanding operating environments.

Series & Parallel Design Flexibility

While the standard configuration is 2S1P, these lithium-ion battery packs can also be expanded into other voltage and capacity combinations when required by the application. Common configurations derived from 3.7V cells include:

• 1S (3.7V) for low-power portable devices
• 2S (7.4V) for handheld electronics and monitoring equipment
• 3S (11.1V) for communication devices and control systems
• 4S (14.8V) for industrial electronics and backup power

Parallel configurations can be added to increase total capacity, such as 2S2P or 2S3P, while maintaining the same voltage level. This modular design approach allows Long Sing Energy to deliver customized solutions while preserving the electrical stability that 7.4V 2S1P Batteries are known for.

Each pack is equipped with a PCM (Protection Circuit Module) that provides protection against overcharge, over-discharge, overcurrent, and short circuits. This ensures safe operation and prolongs the service life of the battery in real-world use.

Application Scenarios

Thanks to their compact size and stable voltage output, 7.4V 2S1P Batteries are widely used in a variety of applications, including:

• Consumer electronics such as portable devices, handheld terminals, and smart equipment
• Medical devices including portable monitors and diagnostic tools
• Industrial electronics like controllers, testers, and data collection units
• Security and monitoring systems
• IoT and smart devices requiring reliable backup or primary power

The balance between size, voltage, and capacity makes this battery pack a practical choice for designs where space efficiency and safety are equally important.
