Explore our state-of-the-art ODM & OEM battery configurations engineered for durability, system integration, and extreme duty-cycle operations.
The global transition from fossil fuels and lead-acid chemistries to advanced lithium-ion technologies is redefining industrial power supply chains. In modern manufacturing, lithium iron phosphate (LiFePO₄) has emerged as the premier chemistry for stationary energy storage, heavy-duty utility vehicles, marine deep-cycle applications, and municipal micro-grids. Today's global market demands high energy density, unparalleled thermal stability, and long cycle lifespans.
As governments globally implement stringent net-zero goals, global companies face a double challenge: procuring high-performance energy storage platforms that satisfy strict localized grid standards while keeping acquisition costs competitive. Custom Original Design Manufacturer (ODM) and Original Equipment Manufacturer (OEM) services play an essential role here. They allow corporations to build custom solutions that seamlessly match their machinery, grid architecture, and spatial constraints.
Technological innovations, regulatory mandates, and supply chain shifts are steering the global battery storage sector toward more sustainable, high-capacity, and intelligent architectures.
Unlike NMC cells, Lithium Iron Phosphate offers superior thermal stability and a long operational lifespan (often exceeding 6,000 cycles at 80% DOD), making it the optimal choice for commercial and industrial ESS.
Modern battery platforms feature cloud-connected Battery Management Systems (BMS). Real-time telemetry monitoring, cell balancing, and predictive state-of-health diagnostics prevent system shutdowns.
Global shipping and safety regulations (UN38.3, UL1973, CE, FCC) require battery modules to withstand extreme thermal, electrical, and mechanical stress without triggering runaway conditions.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a recognized high-tech enterprise specializing in the R&D, manufacture, and deployment of premium lithium-ion batteries, smart BMS architectures, and custom energy storage solutions.

Our slim, wall-mounted and modular floor-standing units integrate smoothly with rooftop solar panels, providing automatic backup power during outages and optimizing peak/valley electricity rates.
Engineered for mobile off-grid power, these lightweight LiFePO₄ batteries replace heavy lead-acid options. They deliver stable voltage outputs and withstand heavy vibration during off-road travel.
Designed to power material handling equipment and commercial golf carts, our high-voltage (48V/72V) packs feature quick-charging capabilities and deep-cycle durability to keep fleets running.
As the battery industry evolves rapidly, Grenergy stays ahead by continuously developing next-generation energy storage tech. Our R&D efforts focus on several key areas:
By investing in these emerging technologies, Grenergy ensures that our ODM partners receive future-ready power products that remain compatible with evolving global grid and safety standards.
Exporting high-capacity lithium battery systems internationally requires strict compliance with dynamic shipping, transportation, and safety guidelines. Grenergy maintains rigorous quality control at every phase of production, from raw material validation to final product testing.
Our manufacturing and testing facilities are certified to international standards, including ISO 9001, ISO 14001, and ISO 45001. Individual battery packs undergo testing to secure certifications like UL, CE, FCC, PSE, and UN38.3, ensuring trouble-free global transit and site acceptance. To provide additional confidence for our partners, all exported products are backed by a $3 million USD product liability insurance policy.
From day one, Grenergy's core mission has been to develop clean, reliable, and efficient energy systems. We envision a future powered by sustainable grids, and our battery designs are built to accelerate that transition.
Through close partnerships with leading component manufacturers and micro-grid integrators, we deliver advanced power systems that combine performance with environmental responsibility. Our systems help businesses transition away from legacy lead-acid setups toward clean, long-lasting LiFePO₄ platforms.
Grenergy works closely with system integrators, fleet managers, and industrial equipment distributors worldwide. We provide full technical support throughout the product lifecycle, from initial concept to end-of-life battery recycling.
Our clients span the renewable energy, telecommunications, transport, and manufacturing sectors. They trust our team to supply dependable, long-life energy storage systems that perform consistently under demanding operating conditions.

LiFePO₄ batteries deliver substantial performance advantages: they offer up to four times the energy density of lead-acid, last 10 times longer (typically 4,000 to 6,000 cycles at 80% Depth of Discharge), require no maintenance, and are significantly lighter. Additionally, they remain highly stable across varying temperatures and contain no toxic heavy metals.
Our ODM development process starts with gathering detailed requirements, including voltage, capacity, peak current, space constraints, and communication protocols. We then proceed with engineering design (electrical schematics, mechanical drawings, thermal simulation, BMS configuration), prototype creation, safety validation, and automated production setup once the prototype is approved.
All battery packs are certified under UN38.3, proving they pass critical vibration, impact, thermal, and short-circuit tests. We package all shipments using UN-certified materials and clear labeling. Our teams coordinate with licensed logistics providers to ensure compliance with hazardous materials shipping guidelines for ocean, air, and land freight.
Yes, our R&D team can customize our BMS firmware to match standard industrial communication systems, including CANopen, Modbus RTU/TCP, and custom RS485 protocols. This ensures smooth integration and accurate telemetry mapping when retrofitting older machinery or linking with modern solar inverters.
The product liability insurance policy provides financial protection against liability claims related to product safety. It gives our commercial clients and distributors global peace of mind, showing that we stand behind the build quality, materials, and safety engineering of our entire product line.
