Watch Our Battery Assembly

Want to see how our lithium battery packs come together? Check out our videos—cell by cell, step by step. From scooters to tools to energy storage, see how we make them reliable and ready to use.

This video walks through the real DIY battery pack assembly process, showing how lithium battery packs are built step by step—from cell matching and spot welding to BMS installation, insulation, and final testing. It gives a clear look at how a professional battery pack manufacturer handles both small custom orders and large-scale production.

As factory specializing in lithium-ion battery pack manufacturing, we support OEM and wholesale battery pack supply for global B2B customers. Our production covers common cell types like 18650 battery and 21700 battery, and can be customized based on voltage, capacity, size, and application requirements. Whether it’s a prototype or mass production, the same attention is given to consistency, safety, and performance.

These DIY battery packs are widely used in real-world applications such as drones (UAVs), electric power tools, solar energy storage systems, backup power units, and various electric mobility and industrial devices. Each application has different demands, so we design and assemble packs to match specific discharge rates, cycle life expectations, and working environments.

As a direct battery pack factory, we focus on wholesale supply and long-term cooperation with distributors, system integrators, and equipment manufacturers. Our goal is to provide stable production capacity, reliable quality control, and flexible customization for different markets.
