Explore our premium selection of original design manufactured (ODM) and original equipment manufactured (OEM) backup energy storage units, RV deep-cycle integrations, golf cart dynamic power modules, and portable stations.
The global energy storage ecosystem is transitioning from legacy chemistries to highly stable, high-density Lithium Iron Phosphate (LiFePO4) and Lithium-Ion structures. This paradigm shift is driven by deep electrochemical security, extended operational lifespans, and low maintenance costs. Heavy industrial and commercial users demand systems that not only supply peak shaving and load leveling capabilities but also deliver uncompromising safety records under severe environments.
Modern ODM LiFePO4 batteries feature an ultra-stable olivine crystal structure that prevents structural decomposition at elevated temperatures. Unlike traditional lead-acid systems that deteriorate under partial state of charge (PSOC) conditions, modern LiFePO4 cells maintain a low degradation profile, guaranteeing over 6,000 deep discharge cycles at 80% Depth of Discharge (DOD). This level of durability significantly lowers the Total Cost of Ownership (TCO) across solar microgrids, specialized electric utility vehicles, and mission-critical backup stations.
Procuring batteries at an international B2B level requires matching exact cell balancing parameters, safety metrics, and communication protocols. Industrial buyers require:
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a leading high-tech enterprise specializing in the research, development, and advanced manufacturing of lithium batteries, energy storage systems, power batteries, battery management systems, and comprehensive all-in-one customized clean energy solutions. Driven by a culture of technological innovation and manufacturing excellence, Grenergy supplies key global industries with highly reliable power systems designed to meet distinct operational specifications.
Operating from a state-of-the-art facility spanning nearly 10,000 square meters and supported by over 200 highly skilled engineering and production professionals, we maintain the capacity to manufacture high-quality battery systems at scale. Our rigorous manufacturing processes conform to elite international management practices, validated by our ISO9001, ISO14001, and ISO45001 certifications.
For more than ten years, Grenergy has committed to replacing inefficient, polluting legacy power systems with sustainable lithium-iron alternatives. Our product engineering covers everything from Lead-acid replacement lithium units to wall-mounted power walls, high-capacity utility storage arrays, and mobile, industrial-grade trolley power packs. We operate on three fundamental values: absolute integrity, technological innovation, and complete client satisfaction.
To safeguard the interests of international system integrators and distributors, all Grenergy products meet demanding safety standards, holding certifications including UL, CE, FCC, PSE, and UN38.3. Furthermore, our complete line of lithium-ion and LiFePO4 batteries is backed by a USD 3 million third-party product liability insurance policy, offering peace of mind to our commercial partners.
We maintain close technology partnerships with first-tier component suppliers, system designers, and safety inspectors. This collaborative matrix allows us to incorporate state-of-the-art BMS algorithms and optimize structural cell layouts, ensuring our custom packs remain robust and high-performing throughout their full operational lifetime.
Our manufacturing footprint is equipped with high-precision automated testing, custom cell sorting machines, high-current discharge testing channels, and environmental validation chambers. By keeping strict quality control in-house, Grenergy ensures that every batch of OEM/ODM battery packs matches the specified electrochemical performance, electrical safety, and mechanical dimensions required by global clients.
Cells undergo rigorous automated categorization based on voltage delta, internal resistance, and capacity consistency, ensuring balanced cell degradation across the entire system pack.
Engineered busbars and reinforced mechanical structures house the cells, helping the pack absorb high vibrations in heavy-duty utility and material handling applications.
Every pack is fitted with a custom Battery Management System (BMS) programmed to monitor temperature differentials, protect against over-charge, and control cell balance.
Grenergy's custom lithium battery lines are built to handle demanding industrial and commercial requirements. We specialize in developing energy platforms that power challenging environments:
Modern photovoltaic installations demand storage units capable of cycling daily without thermal stress. Grenergy’s high-capacity floor-mounted systems (such as the 51.2V 314Ah Home Backup series and the 200Ah LiFePO4 Wall Battery) provide the high energy density and round-trip efficiency needed to capture and dispatch solar generation, reduce peak grid demand charges, and keep operations running through grid disturbances.
Utility vehicles, AGVs, port tractors, and golf carts demand reliable power under variable mechanical vibrations and thermal loads. Our specialized high-voltage vehicle batteries (such as the ODM 76.8V 100Ah Lithium Battery) deliver high power output, charge quickly, and require zero maintenance, helping industrial operators maximize fleet utilization and reduce downtime.

As a forward-looking ODM battery exporter, Grenergy is constantly updating its electrochemical and electrical management systems. Our current development pipeline focuses on three key technological areas:
Transporting and installing large-scale lithium batteries is a heavily regulated process. As a long-standing exporter, Grenergy maintains complete documentation and logistics control. We ensure that our battery packs conform strictly to international transport criteria, including UN38.3 (lithium battery safe shipping protocol) and international maritime dangerous goods (IMDG) codes.
We provide complete documentation, technical datasheets, and certificates of conformity for all custom projects. This regulatory compliance, coupled with our $3 million product liability policy, helps global distributors, installers, and importers secure local municipal project approvals and manage operational risks.
Our engineering team works closely with your development team. From initial electrical specification mapping and CAD structural drafting to prototype validation, dynamic thermal modeling, and volume assembly, we ensure that your custom battery systems fit seamlessly into their final application housings.
Based on frequent inquiries from global procurement managers and system integration engineers, we have compiled detailed answers to help you navigate the process of sourcing custom ODM/OEM batteries.
LiFePO4 (Lithium Iron Phosphate) offers superior thermal stability, safety, and an extended cycle life (typically 4,000 to 7,000 cycles), making it well-suited for stationary storage and industrial vehicles. NMC (Nickel Manganese Cobalt) has a higher energy density by weight, making it popular for passenger electric vehicles and compact consumer devices where space and weight are critical constraints.
We run all incoming cells through automated sorting machines to check capacity, open-circuit voltage (OCV), and internal resistance (IR). Cells are only grouped into packs if they fall within strict deviation limits, which helps prevent uneven degradation and extends the operational lifetime of the pack.
Our custom Battery Management Systems support industrial communication interfaces including CANbus, RS485, Modbus RTU, and RS232. This enables real-time system monitoring, integration with off-grid inverters, and remote system diagnostics.
Our USD 3 million product liability policy covers third-party bodily injury and property damage worldwide. This safety net helps mitigate risk for our distribution partners and commercial buyers, assuring them of our build quality and product reliability.
Yes, we manufacture standard and custom-dimensioned lead-acid replacement packs (typically 12.8V, 24V, and 48V models). These packs feature integrated BMS protection and are built to drop directly into existing lead-acid compartments on golf carts, RVs, and marine vessels.
