Explore our premium wholesale-grade LiFePO4 configurations engineered for high energy density, maximum thermal stability, and integrated smart BMS technology.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a national high-tech enterprise specializing in the research, development, and manufacturing of advanced lithium-ion and lithium iron phosphate (LiFePO4) batteries. Over the last decade, we have dedicated ourselves to offering complete energy storage solutions, smart Battery Management Systems (BMS), and all-in-one power solutions for residential, commercial, industrial, and off-grid clients globally.
Grenergy’s founding mission is to design clean, efficient, and long-lasting alternative energy systems to mitigate climate footprints. Focusing primarily on LiFePO4 chemistry—known for its safety profile and incredible longevity—our engineering teams continuously push boundaries in thermal dissipation, high-voltage battery management systems, and mechanical safety integration.
Since inception, our roadmap has mirrored the explosive growth of clean tech. As lead-acid replacement markets transformed, Grenergy evolved from a small cell-pack integrator into a fully-fledged automated OEM/ODM factory occupying nearly 10,000 square meters of advanced production floor in Shenzhen. Our product portfolio spans Lead-acid replacement lithium batteries, Wall-mounted power walls, Portable power stations, Mobile home energy storage systems, and specialized Trolley box portable power stations.
Guided by our core values of integrity, innovation, and client satisfaction, we continuously refine our engineering to protect investments, ensure zero operational down-time for our enterprise partners, and deliver scalable green energy solutions that facilitate the transition to renewable energy.


Decoupling energy manufacturing from primary raw supply lines is inefficient. Located at the epicenter of global battery production—Shenzhen, China—Grenergy leverages deep geographic proximity to the world's finest cathode refineries, smart BMS chip fabs, and highly optimized hardware suppliers.
By negotiating directly with lithium iron phosphate cathode processors and tier-1 raw cell suppliers, we secure structural price stability for large enterprise contracts. Our raw cell supply chains undergo rigorous aging and sorting protocols prior to assembly.
Our facility houses automated spot welding machines, automated BMS diagnostic testing benches, environmental chamber simulations, and multi-channel charge-discharge cycling units. This layout eliminates human error and accelerates output capabilities.
Each cell batch is matching-graded based on capacity, internal resistance, and voltage curve alignment. Finalized battery packs are subjected to 100% full-cycle testing before packaging, eliminating factory defects prior to international shipping.
Grenergy specializes in customizing products down to the base level to fulfill client specifications. Whether you require specific communication protocols (CANbus, RS485, RS232, Modbus), unique metal housing dimensions, custom LCD interfaces, or customized voltage configurations (from 12V to high-voltage 76.8V and higher), our team of 200 dedicated professionals is trained to implement industrial designs rapidly.
Enterprise procurement managers can leverage our in-house engineering lab to mock up product prototypes, run thermodynamic test cases, and implement software optimizations for custom BMS algorithms.
Entering international markets with battery products requires meticulous regulatory compliance. Navigating safety standards, transportation clearance, and local safety rules is crucial. Grenergy simplifies this path for global importers by maintaining a world-class regulatory portfolio.
Our production systems are certified to ISO9001, ISO14001, and ISO45001 standards. Our battery designs carry full certifications for regional markets, including UL (for US/Canada), CE & RoHS (for Europe), PSE (for Japan), FCC (for EM susceptibility), and UN38.3 (for shipping safety).
Lithium batteries are classified as Class 9 Dangerous Goods. We offer comprehensive logistics packages, including sea, rail, and air freight, with complete Material Safety Data Sheets (MSDS), UN38.3 test summaries, and certified dangerous goods packaging.
We work closely with local engineering consultants, solar installers, and system integrators to troubleshoot firmware compatibility issues, supply direct replacement components, and support your regulatory submissions.
Data drives our modern quality control systems. Grenergy uses a digital factory management protocol to monitor every step of production. Every battery pack is assigned a digital barcode, allowing us to trace individual cell capacities, weld parameters, testing results, and packaging logs indefinitely.
We believe in a future powered by clean, renewable energy. Our lithium batteries are designed to support this transition, helping businesses around the world move away from legacy diesel generator systems and high-maintenance lead-acid packs.
Through close collaborations with industrial partners, research institutions, and raw material suppliers, we keep our systems at the cutting edge of energy storage technology. This focus on engineering excellence has helped us build long-term relationships with businesses across Europe, North America, Japan, and Southeast Asia.
Modern battery architectures must handle diverse environmental conditions and operational loads. Grenergy designs customized, durable products for a wide variety of commercial and residential applications.
Wall-mounted and rack-mounted battery systems interface with solar inverters to capture solar power during the day, reducing electricity bills and providing backup power during blackouts.
High-voltage, high-capacity battery packs deliver consistent power and rapid charge times for utility carts, golf carts, and electric material handling equipment.
Rugged, portable trolley power stations and compact batteries supply reliable energy for remote job sites, search-and-rescue teams, and off-grid work.
Lightweight, high-capacity 12.8V batteries replace heavy lead-acid options, providing long-lasting power for auxiliary electronics on RVs, campers, and marine craft.
We work closely with semiconductor developers, inverter manufacturers, and software engineers to ensure our battery systems communicate seamlessly with the latest power grids and hybrid inverters. This collaborative approach allows us to deliver reliable, turn-key storage solutions to installers worldwide.
The energy storage sector is shifting rapidly, driven by grid upgrades, battery cost efficiencies, and evolving green regulations. Businesses should prepare for several key technological trends:
Due to its high thermal runaway threshold (around 270°C, compared to 150°C for traditional NMC batteries), LiFePO4 has become the standard chemistry for stationary storage and commercial vehicles. It is non-toxic, uses no cobalt, and provides up to 6,000 charge cycles, making it a highly cost-effective choice over the long term.
System designers are increasingly moving from 12V and 24V configurations to high-voltage platforms (51.2V up to 76.8V and beyond). Higher operating voltages reduce current flow, which lowers line losses, simplifies system cabling, and improves overall power conversion efficiency.
Modern Battery Management Systems do more than just balance cells. They now use smart microcontrollers that stream diagnostic data to cloud monitoring dashboards via IoT networks. This allows managers to track cell health, balance voltages, and monitor temperatures in real time.
Commercial fleets, marine operators, and telecom companies are replacing legacy lead-acid systems with modern lithium packs. LiFePO4 batteries are lighter, charge faster, require zero maintenance, and provide much deeper discharge capabilities without damage.
