Preface
Electric power shall be available for everyone and everywhere, at an affordable and reasonable price. We don't generate the electric power - we do the storage, and dedicated to providing efficient, safe and stable battery power supply to every need.
Profile
Building on 21 years of foundational battery manufacturing expertise since 2004, Grand Energy Manufacturing Co Ltd (known as GEMFG) has strategically evolved from lead-acid production into a specialized lithium battery pack innovator. Our journey began with establishing robust lead-acid systems at our Quanzhou facility, cultivating deep insights into power solution reliability. Recognizing the energy transition, we founded GRAND ENERGY TECH (XIAMEN) CO LTD (known as GET) in 2016 as a dedicated R&D engine to master lithium chemistry, cell integration, and safety architectures. This research excellence paved the way for our 2021 joint venture with Guangdong Tiequan New Energy Technology Co., Ltd., launching purpose-built lithium manufacturing under the GEMFG brand in Dongguan. Today, this 3,500m² ISO-certified hub consolidates our lithium operations, where 50+ engineers transform 21 years of electro-mechanical proficiency into industry-leading battery packs.
Monthly producing 45 MWh (equivalent to 15×40' FCL containers), we implement maturity-proven processes: From cell validation to proprietary BMS calibration, every step integrates ISO 9001/14001/45001, UN38.3, and CE-certified quality protocols. Our packs deliver uncompromising cycle life and safety-not through experimentation, but through hard-won manufacturing discipline refined over two decades. For global partners seeking lithium solutions where reliability transcends specifications, GEMFG stands as your experience-guaranteed source.

Professionals
As a specialized lithium battery pack manufacturer serving diverse applications - Solar | UPS | Telecom | BESS | Motorcycle | High-Voltage Motive Power | E-Bike | Scooter | Forklift | Sweeper and industrial electric vehicles - GEMFG transforms premium lithium-ion cells into high-performance, safety-focused power solutions through advanced system integration. Our "Powered and Powerful" commitment drives a grounded quality ecosystem dedicated to pack-level excellence:
→ Cell Validation: Rigorous incoming checks via automated grading systems and real-world performance profiling ensure consistency in capacity, impedance, and thermal behavior.
→ Module Assembly: Automated laser welding with thermal monitoring guarantees robust electrical connections, while precision vision inspection verifies structural integrity and optimal cell spacing for thermal management.
→ Pack Integration: Proprietary BMS fine-tuned through exhaustive in-house testing delivers precise cell balancing and multi-tier protection against electrical faults.
→ Environmental Protection: All enclosures achieve IP21+ ratings validated through physical seal testing.
Leveraging proven automation (cell sorters, laser welders, aging equipment), we ensure manufacturing repeatability. Safety is proven through hands-on abuse testing: Vibration rigs simulate years of operational stress • Mechanical crush trials validate structural resilience • Controlled thermal propagation assessments confirm containment efficacy. Every batch undergoes real-world performance mapping - from sub-zero cold starts to high-temperature fast-charging - with full component traceability.
This practical approach delivers optimized energy density, extended cycle life, and failsafe operation across all applications, establishing GEMFG as your trusted partner where real-world reliability outweighs theoretical benchmarks.
Power Solution
Drawing on extensive collaboration with diverse clients, GEMFG leverages decade-honed expertise to engineer optimal lithium battery pack solutions for any application-from rechargeable applications, energy storage to industrial electric vehicle. As a specialized pack integrator, we meticulously select premium third-party cells and components, then apply proven system integration methodologies to tailor performance to exact requirements. Our engineering team conducts rigorous configuration analysis, optimizing BMS programming and structural design to ensure each pack delivers targeted energy density, cycle life, and safety margins. Whether for consumer devices, critical backup systems, or extreme-environment applications, we transform validated raw materials into purpose-built power solutions where precise voltage regulation, thermal stability, and real-world reliability define every pack we assemble.
