Explore our premium custom battery products, engineered to address modern off-grid, backup, and industrial electric power integration challenges.
As the international transition towards decentralized green energy accelerates, portable power systems (PPS) and mobile energy storage systems (ESS) have transformed from recreational conveniences to mission-critical infrastructure. Severe weather patterns, aging national grid systems, and rising carbon taxes drive corporations to seek autonomous power backup solutions.
Industries such as emergency telecommunications, temporary commercial medical clinics, deep agricultural fields, and heavy construction sites require robust, reliable power that diesel generators can no longer sustainably provide. By utilizing lithium iron phosphate (LiFePO₄) chemistries, modern OEM power systems offer long lifespan utility, low thermal runaway risk, and stable voltage profiles to run complex industrial equipment safely.
Global corporations increasingly look to establish reliable manufacturing relationships that can scale from small, compact portable packs (like trolley-type systems) to large containerized backup configurations. Securing a trusted partner capable of meeting global energy standards is vital for market compliance, risk management, and competitive product positioning.
A decadelong legacy of battery engineering, technological precision, and strict international compliance.
Established in 2010, Shenzhen Grenergy Technology Co., Ltd. is a national high-tech enterprise focused on the research, development, and advanced manufacturing of lithium-ion batteries, smart energy storage systems (ESS), motive power batteries, custom Battery Management Systems (BMS), and all-in-one smart microgrid solutions. Through relentless pursuit of technical excellence, Grenergy supplies key global industries with safe and efficient energy systems.
Over the last decade, Grenergy's core brand promise has centered on engineering integrity and technical innovation. By constantly adapting to emerging battery standards, our dynamic portfolio now covers drop-in Lead-Acid replacement lithium batteries, wall-mounted home energy storage units, rack-mounted system integration modules, high-capacity golf cart power packs, and heavy-duty trolley-style portable power stations designed for rough outdoor operations.
Certified ISO9001, ISO14001, and ISO45001. We conduct 100% automated testing on individual cell capacities, safety mechanisms, and thermal behaviors before shipping.
Tailor your battery capacity, BMS output logic, metal housing, display interface, and port structures to target localized market demands seamlessly.
Our solutions carry international safety clearances including UL, CE, FCC, PSE, and UN38.3, removing complex logistics and regulatory barriers for B2B buyers.
China operates at the global epicenter of the advanced lithium battery supply chain. Producing over 75% of the world's lithium-ion chemistries, the country offers unparalleled access to upstream raw materials, high-density cell production, and specialized mechanical engineering. For overseas B2B buyers, this translates into shorter production cycles, dynamic scalability, and major cost advantages.
Our 10,000 square meter production facility in Shenzhen leverages this robust ecosystem. Supported by over 200 skilled operators and advanced automated inspection lines, we minimize cycle differences between battery packs. This keeps the Levelized Cost of Storage (LCOS) highly competitive, allowing foreign brands to enjoy premium product quality without the typical domestic cost premiums.
Additionally, we mitigate international market risk by securing a $3 million USD product liability insurance policy. This comprehensive safety net ensures that our international distributors, integration partners, and commercial end-users are legally and financially insulated against unexpected structural or operational liabilities.
How Grenergy's multi-tier battery systems solve real-world industrial and residential power challenges.
Rack-mounted modules provide modular, hot-swappable energy backup for sensitive IT cabinets, telecommunications infrastructure, and high-frequency edge computing setups.
Deep-cycle 12.8V 100Ah/300Ah LiFePO₄ batteries replace heavy lead-acid options. They deliver stable off-grid power to RV air conditioners, cooking appliances, and navigation computers.
High-capacity wall-mounted and floor-mounted systems (like our 5.12kWh and 51.2V 314Ah setups) store off-peak solar power to lower electric bills and provide emergency backup during blackouts.
Heavy-duty lithium replacement packs for golf carts and commercial utility vehicles provide long shift operations, zero daily maintenance, and rapid-charge capabilities.
To stay ahead in the energy market, manufacturers must innovate continuously. Grenergy focuses on key industry advancements to keep our clients competitive:
A streamlined, reliable production pipeline designed to bring your proprietary power systems to market quickly.
No two projects share the exact same load profiles, environmental stresses, or regulatory constraints. That is why Grenergy provides complete design freedom. From custom metal enclosures and localized communication protocols to specialized cell matching, we build systems that fit your technical goals.
We work closely with global utility suppliers, industrial distributors, and outdoor appliance brands. Our production process ensures that every stage—from initial CAD modeling to cell sorting, BMS configuration, safety testing, and export clearance—runs efficiently and reliably.
