Explore our flagship private label lithium iron phosphate (LiFePO4) storage batteries, portable generators, and vehicular power solutions engineered for peak global performance.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. has pioneered the international green energy paradigm for over a decade. We operate as a high-tech enterprise specializing in the comprehensive R&D, precision manufacturing, and strategic exportation of elite-class lithium iron phosphate (LiFePO4) cells, smart Battery Management Systems (BMS), residential and commercial energy storage structures (ESS), and turnkey system integrations.
Since our inception, our core mission has revolved around empowering the global transition toward decarbonization through robust, clean, and extremely safe energy storage technologies. Our diverse product portfolio spans lead-acid replacement batteries, space-optimized wall-mounted power walls, high-voltage rack systems, smart portable power stations, and custom engineered mobility battery packs.
Grenergy’s history is defined by continuous manufacturing innovation, strict engineering ethics, and a steadfast dedication to providing premium B2B custom private label manufacturing to clean-tech companies, power grids, and vehicle brands worldwide.
The global shift toward sustainable energy has pushed advanced battery chemistries to the absolute forefront of industrial design. Among these, Lithium Iron Phosphate (LiFePO4) represents the gold standard for applications requiring high safety, long cycle life, and thermal resilience. As a premier private label exporter, Grenergy has focused strictly on this chemistry to replace volatile ternary lithium (NMC) configurations and obsolete, ecologically hazardous Lead-Acid architectures.
In high-capacity applications, safety is not merely a feature—it is the paramount engineering threshold. The olivine crystal structure of LiFePO4 features robust covalent P-O bonds, which are structurally and chemically stable at much higher temperatures than the metallic bonds in NMC or LCO chemistries. LiFePO4 does not release oxygen upon thermal breakdown, eliminating the primary driver of spontaneous combustion. Its thermal runaway threshold lies above 600°C, compared to roughly 220°C for NMC. This inherent safety makes it ideal for dense residential environments (home powerwalls) and heavy vibration settings (golf carts, commercial transport, and military RV conversions).

From an enterprise level, the Levelized Cost of Energy (LCOE) determines the viability of solar grid installations. Standard Lead-Acid batteries provide a meager 300 to 500 charge-discharge cycles before dropping below 80% capacity. In contrast, Grenergy's Grade-A LiFePO4 systems routinely achieve 3000 to 6000 complete cycles at 80% Depth of Discharge (DoD). This long lifespan translates directly to over 10 to 15 years of daily operation in typical residential solar microgrids, drastically reducing capital replacement expenditures and ongoing field maintenance costs.
China continues to command over 70% of the world's lithium-ion battery manufacturing capacity. This dominance is not built on labor costs alone, but on a highly integrated, massive industrial ecosystem. By partnering with a Shenzhen-based OEM/ODM exporter like Grenergy, global businesses leverage this ecosystem to secure cost, performance, and lead-time advantages that are unattainable in other regions.

Global logistics demand strict compliance with international safety protocols. Grenergy operates under rigorous quality guidelines, backed by international standards including ISO9001, ISO14001, and ISO45001. Our products undergo rigorous UN38.3 thermal shock, vibration, short circuit, and impact testing to guarantee safety during transportation. Additionally, our consumer and industrial lines carry UL, CE, FCC, and PSE certifications. We offer a $3 million USD third-party product liability insurance policy on all products, providing an extra layer of commercial protection and peace of mind for our global B2B procurement partners.

Our commitment to excellence has helped us build relationships with key partners worldwide. By working closely with leading component manufacturers and engineering firms, we ensure that our batteries integrate seamlessly into larger power systems. From residential microgrids to heavy industrial operations, our collaborative approach ensures that our solutions deliver reliable, long-term performance.
Modern energy requirements vary greatly by region and industry. As a versatile exporter, Grenergy designs specialized configurations to meet these distinct application demands.
Our floor-mounted and installer-friendly wall-mounted battery systems serve as the core of home solar setups. These systems store excess solar energy generated during the day for use during peak pricing hours or grid outages. Equipped with intelligent BMS, they integrate seamlessly with hybrid inverters to enable auto-switching back-up power, ensuring energy independence and lower utility bills.
Traditional lead-acid golf cart batteries suffer from quick voltage drops, heavy weight, and high maintenance needs. Our 51.2V and 76.8V high-performance lithium conversions offer stable voltage throughout the entire discharge cycle. This weight reduction (often saving up to 300 lbs per vehicle) increases speed, reduces wear and tear, and delivers three times the driving range without any maintenance.
Off-grid travel requires reliable power. Our deep-cycle 12.8V batteries are drop-in replacements for standard lead-acid batteries. They deliver stable power for lighting, refrigeration, electronics, and air conditioning. They also charge up to 5 times faster from alternator chargers or solar systems, making off-grid travel simple and reliable.
