A decade of battery pack manufacturing excellence. From the heart of China's electronics ecosystem.
Our Shenzhen headquarters houses R&D, prototyping, and small-batch production. Our Dongguan facility handles large-volume assembly with automated spot-welding lines, laser marking stations, and end-of-line test systems.
Combined capacity exceeds 200,000 packs per month across all form factors, from coin-cell assemblies to rack-mount 48V storage systems.
ISO 9001:2015 certified quality management system. Every production batch undergoes inline QC checks and full functional testing before shipment.
We purchase cells directly from the world's leading manufacturers. No brokers. No gray market. Full traceability from cell to pack.
