Explore our premium selection of integrated lithium iron phosphate systems designed for marine, recreational vehicle, domestic backup, and commercial grid integration.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a nationally recognized high-tech enterprise specializing in the research, development, assembly, and worldwide distribution of advanced lithium batteries, robust energy storage systems (ESS), industrial motive power packs, and integrated smart Battery Management Systems (BMS).
Our commitment lies at the intersection of environmental sustainability and robust industrial performance. Over the past decade, we have scaled our production facilities to supply critical energy sectors globally. Our engineering focuses on substituting lead-acid dependencies with high-lifecycle Lithium Iron Phosphate (LiFePO4) systems that reduce total ownership cost and minimize thermal risks.
Grenergy’s brand history is rooted in constant evolution. We began by providing high-quality custom battery assemblies for local tech hardware manufacturers. As global demand shifted towards sustainable electrification, we transitioned into high-capacity LiFePO4 cells, rack-mounted ESS architectures, and compact residential backup stations.
Our operational framework focuses on three pillars: safety, longevity, and ease of installation. Today, we assist international business partners in replacing outdated generator units and lead-acid backup systems with intelligent, maintenance-free lithium solutions, decreasing carbon footprints while ensuring reliable energy delivery in volatile microgrid environments.
At Grenergy, we view energy storage not merely as a backup mechanism, but as the foundational infrastructure for the next generation of grids. Our systems allow commercial entities to achieve peak-shaving, enable off-grid RV users to travel further safely, and guarantee that residential units remain powered during emergency brownouts.
By utilizing advanced thermal design, automated cellular matching, and dynamic BMS parameters, we have gained trust across North America, Europe, Australia, and Asia-Pacific. We continue to innovate by maintaining an active feedback loop with global installers and engineers.

The transition to lithium energy storage is driven by rising global demand, decarbonization policies, and technological innovation. Below are key trends shaping the industrial energy storage landscape.
Lithium Iron Phosphate (LiFePO4) chemistry has surpassed cobalt-based variations (NMC/LCO) in stationary and commercial energy systems. Because LFP exhibits an exceptional thermal runaway threshold, zero toxic heavy metal profile, and superior cycle life (often exceeding 6,000 cycles at 80% Depth of Discharge), global standard agencies prefer it for public and residential installations.
Raw hardware is no longer the sole differentiator. Powertech lithium systems now demand digital layers that monitor cell balance, state-of-charge (SoC), state-of-health (SoH), and micro-temperature fluctuations in real-time. Modern communication interfaces (CANbus, RS485, Modbus) must integrate with popular clean-energy inverters like Victron, Growatt, and SMA.
Modern commercial and residential projects require plug-and-play modularity. Scalable form factors allow installers to combine multiple rack-mounted batteries or wall-mounted power walls to meet unique client capacity profiles. This eliminates complex system redesigns and keeps inventory costs low.
Global procurement teams prioritize security, certification compliance, and manufacturing capacity. With nearly 10,000 square meters of production space and a team of 200 highly skilled professionals, Grenergy meets these demands at scale.
Our custom OEM/ODM services allow clients to adapt battery parameters, enclosure shapes, cooling solutions, and BMS protocols. Whether you require a specialized 12.8V RV battery for custom vehicle integrations or a high-density 51.2V 314Ah rack system for industrial backup, we provide solutions that match your technical requirements and local certification guidelines.
To ensure system safety, we source premium prismatic cells and carry out multi-stage testing, including aging simulations, thermal cycle testing, and vibration profiles. Through partnerships with industry-leading materials suppliers and testing institutions, we stay ahead of regulatory changes, ensuring rapid and safe customs processing for imports.
From residential solar installations to utility microgrids, our custom systems deliver reliable power configurations tailored to local environments and compliance rules.
Our wall-mounted and rack-mounted batteries integrate with solar arrays to store excess day-time energy. By managing peak loads and offering power during grid failures, these systems protect key assets in hospitals, telecommunication hubs, and cold storage facilities.
Heavy-duty systems like golf carts, automated guided vehicles (AGVs), and scissor lifts require sustained high-current delivery and fast recharging cycles. Our 51.2V and 76.8V custom lithium assemblies maximize operation times and eliminate the maintenance required by lead-acid batteries.
Recreational vehicle and marine markets require compact energy density and vibration resistance. Our high-capacity 12.8V LiFePO4 packs feature structural reinforcement and advanced BMS monitoring, protecting system components during off-road travel.
Importing large-format batteries requires strict compliance. Our manufacturing facility complies with international standards, holding certifications for ISO9001, ISO14001, ISO45001, UL, CE, FCC, PSE, and UN38.3.
To reduce risk for distributors and installers, we provide a third-party product liability insurance policy valued at $3 Million USD. This covers our entire product line, protecting your business from financial liabilities during installation and long-term operation.
Our research and development program focuses on three main initiatives:
Get authoritative answers to common questions about purchasing, customizing, and installing Powertech Lithium Batteries.
Lithium Iron Phosphate (LiFePO4) features a strong molecular structure that does not release oxygen upon thermal breakdown. Its thermal runaway temperature threshold is approximately 270°C, compared to 150°C for Nickel Manganese Cobalt (NMC) cells. This difference makes LiFePO4 far more stable and resistant to fire or combustion under physical impact or electrical abuse.
Our custom battery management systems support CANbus, RS485, RS232, and Modbus protocols. This ensures compatibility with leading global inverter brands such as SMA, Victron Energy, Growatt, Deye, and GoodWe, allowing for seamless integration and real-time remote monitoring.
Every cell undergoes strict grading processes to evaluate capacity, internal resistance, and voltage stability. We only use A-grade prismatic cells, and we perform dynamic capacity matching before structural pack integration. We also conduct comprehensive charge/discharge validation cycles to ensure reliability.
Our battery packs carry UN38.3 certification, which is mandatory for international maritime and air cargo transport. In addition, we supply complete MSDS (Material Safety Data Sheets), test reports, and transport safety certifications to ensure hassle-free customs clearance worldwide.
This insurance policy offers financial protection for distributors, engineering firms, and end-users against losses resulting from manufacturer design defects or production failures. This reflects our confidence in our production quality and provides peace of mind for projects in North America, Europe, and Asia.
Our wall-mounted and rack-mounted batteries are designed to support over 6,000 continuous charge-discharge cycles at 80% Depth of Discharge (DoD) when operated under nominal temperature conditions (25°C). This translates to more than 15 years of reliable daily operation before capacity drops below 80% of its original rating.
