Explore our cutting-edge range of OEM & ODM lithium-based systems designed for marine, solar, EV, home energy storage, and industrial backup systems.
The global recreational vehicle (RV) industry is undergoing a historical transformation. For decades, deep-cycle lead-acid batteries were the standard for house power systems. However, as mobile lifestyles evolve and off-grid camping (boondocking) grows in popularity, consumers demand access to high-power residential appliances like air conditioners, induction cooktops, microwave ovens, and precision medical devices while off the grid. This demands a massive leap in energy storage capability.
Traditional Lead-Acid technology struggles under high loads due to severe voltage sag, limited depth of discharge (DoD) of 50%, and extensive weight. Lithium Iron Phosphate (LiFePO₄) has emerged as the definitive solution. By offering up to 100% usable capacity, maintaining a stable voltage profile throughout discharge, and delivering over 3,000 to 6,000 duty cycles, lithium batteries have become a necessity for modern luxury RVs, commercial utility vehicles, and mobile mobile-workstations.
“Transitioning from conventional Lead-Acid configurations to active-heated Lithium Iron Phosphate (LFP) banks allows RV builders and commercial fleet specifiers to reduce house battery weight by up to 70% while more than doubling the active runtimes.”
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a premier high-tech enterprise specializing in the research, development, and advanced manufacturing of lithium batteries, integrated energy storage systems, automotive-grade power battery systems, smart Battery Management Systems (BMS), and all-in-one custom industrial energy storage systems. Driven by continuous technological innovation, we have established ourselves as a reliable partner to OEMs, ODMs, and leading industrial energy suppliers globally.
Over the years, our product portfolio has grown to meet complex global application needs. Our comprehensive solutions include high-performance Lead-acid replacement lithium batteries, space-efficient Wall-mounted power walls, rugged Portable power stations, Mobile home energy storage systems, heavy-duty Trolley box portable power stations, and custom energy products. We strive to improve efficiency, reduce carbon footprint, and provide cost-effective life-cycle performance.


B2B energy storage sourcing requires evaluating safety certifications, scalability, logistics support, and supply chain reliability. Grenergy addresses these requirements systematically.
We provide comprehensive OEM and ODM support, including structural sizing, cell-matching configurations, communication integration via CANbus, Modbus, or Bluetooth, and custom enclosure designs for diverse operating environments.
All batches undergo strict testing, including vibration endurance, high thermal load cycling, short-circuit simulations, and overcharge safety validation. We offer products certified under ISO9001, ISO14001, ISO45001, UL, CE, FCC, PSE, and UN38.3 standards.
To secure our global partnerships, Grenergy maintains a $3 million USD third-party product liability insurance policy. This guarantees comprehensive coverage and financial security for global distribution, vehicle manufacturers, and engineering projects.
The core technology behind our wholesale RV batteries relies on optimized cell chemistry and smart control architecture. We prioritize LiFePO₄ (Lithium Iron Phosphate) due to its superior thermal runaway limit (~270°C) compared to standard NCM chemistries (~150°C).
Key technical innovations engineered in our facility include:
Looking ahead, Grenergy is investing in advanced energy management systems, cloud-based fleet monitoring integrations, and solid-state cell variations to increase energy density while maintaining high safety standards.
Our lithium configurations serve a wide range of mobile and stationary energy storage applications.
Optimized 12V, 24V, and 48V LFP systems that integrate into standard RV, camper van, and specialized emergency response vehicle chassis.
Trolley-style portable power stations, compact backup power units, and custom high-output designs for remote work locations and disaster response.
High-voltage battery setups, rack-mountable server units, and wall-mounted setups engineered to pair with modern solar inverters.
Our business is built on reliability, open communication, and long-term customer partnerships. Grenergy works closely with system integrators, design houses, and logistics providers globally to ensure components perform as expected in the field.
Through close partnerships and data sharing, we continuously optimize our production lines, improve materials procurement, and update our BMS configurations. This ensures our partners receive reliable systems that keep their fleets and products operational.
Our engineering team works with customers from prototype stage through volume production, helping minimize design risks and accelerate time to market. We balance our production resources to maintain consistent supply for contract orders while accommodating specialized development projects.
