Customized 3.7V Lithium Ion Battery Pack With Bms Stable Discharge Li Ion 2500mAh Rechargeable Cell

Description

The Customized 3.7V Lithium Ion Battery Pack from Long Sing Energy is designed to deliver consistent performance, long cycle life, and enhanced safety for a wide range of electronic and industrial applications. Based on proven lithium-ion chemistry, this battery pack typically uses 3.7V cylindrical or prismatic Li-ion cells, with 2500mAh as a common single-cell capacity option. Depending on project needs, alternative capacities such as 2000mAh, 2200mAh, 2600mAh, 3000mAh, and higher-capacity cells can also be selected.

Each pack integrates a Battery Management System (BMS) that provides protection against overcharge, over-discharge, overcurrent, and short circuits. This ensures stable voltage output and reliable operation throughout the battery’s service life. The Customized 3.7V Lithium Ion Battery Pack is especially suitable for applications requiring precise energy control and compact form factors.

Series & Parallel Configurations

To meet different voltage and capacity requirements, individual 3.7V cells can be assembled into various series (S) and parallel (P) configurations. Common configurations include:

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

Parallel connections are used to increase total capacity and runtime, while series connections raise the operating voltage. By combining both, the Customized 3.7V Lithium Ion Battery Pack can be precisely tailored to deliver the required voltage, current, and energy density. This flexibility makes it ideal for both standard products and customized electronic designs.

Application Scenarios

Thanks to its adaptable design and stable discharge characteristics, the Customized 3.7V Lithium Ion Battery Pack is widely used across multiple industries, including:

• Consumer electronics such as handheld devices, smart sensors, and portable instruments
• Medical equipment including monitoring devices and portable diagnostic tools
• Industrial electronics like controllers, data loggers, and automation modules
• IoT devices and smart systems requiring long runtime and compact batteries
• Backup power solutions for small-scale energy support

Its stable output and compact structure allow it to perform reliably even in space-constrained designs.
