Product Description

This product is a custom-built 18650 lithium-ion battery pack designed for OEM and ODM projects. It supports a wide range of voltage configurations including 3.7V, 7.4V, 11.1V, 12V, 24V, 36V and 48V, with flexible capacity based on series and parallel design.

Built with selected Grade A 18650 Li-ion cells, the battery pack is suitable for applications requiring stable performance, reliable consistency and long-term project cooperation. Each pack can be customized in terms of voltage, capacity, BMS solution, connector type and enclosure structure to match specific system requirements.

This solution is intended for industrial equipment, energy-related systems and customized electronic devices, rather than retail off-the-shelf products. Engineering-oriented support is provided throughout the project, from configuration design to sample validation and mass production.

This solution is intended for customers seeking a scalable, customizable, and engineering-oriented lithium battery pack, instead of a fixed-parameter consumer battery.

Key Features

Wide Voltage Customization: Supports multiple voltage configurations including 3.7V, 7.4V, 11.1V, 12V, 24V, 36V and 48V through flexible series and parallel design.
18650 Li-ion Cell Based: Built with selected 18650 lithium-ion cells, suitable for stable discharge and long-term project applications.
Smart BMS Integration: Equipped with built-in smart BMS providing over-charge, over-discharge, over-current, short-circuit and temperature protections.
Engineering-Oriented Customization: Voltage, capacity, BMS parameters, connectors, wiring and enclosure can be customized based on project requirements.
Consistent Assembly Quality: Cell capacity grading and internal resistance sorting applied to ensure consistency for series and parallel battery pack assembly.
OEM & ODM Support: Suitable for OEM and ODM cooperation, supporting sample development, validation and stable mass production.
