Overseas Lithium Battery Factory Setup Solution | ONESUN Turnkey SKD/CKD Energy Storage Manufacturing
With the rapid global growth of off-grid energy storage, residential ESS, and commercial & industrial battery systems, more overseas enterprises are seeking to localize lithium battery production. Import tariffs, long delivery cycles, and supply chain instability are pushing distributors, EPC contractors, and energy companies to build local battery assembly factories.
However, setting up a lithium battery factory from scratch is far more complex than expected. Most overseas investors face significant challenges: lack of technical expertise, difficulty managing supply chains, unfamiliarity with factory design standards, and inability to establish a scalable production system. These barriers often result in delayed projects or failed factory launches.
To address these challenges, ONESUN provides a complete turnkey lithium battery factory solution, offering OEM/ODM services and SKD/CKD energy storage manufacturing systems tailored for global B2B clients.
1. Complete Factory Planning & Customized Layout Design
ONESUN delivers full-scale factory planning based on local regulations, production capacity goals, and available infrastructure. From workshop zoning, production flow design, and cleanroom standards to solar integration planning, every detail is engineered for efficiency and compliance.
Our engineering team provides detailed CAD drawings and implementation plans, ensuring that overseas clients can build standardized, cost-effective, and scalable production facilities without costly trial-and-error processes.
2. Precision Production Line Matching & Equipment Supply
A key factor in factory success is choosing the right equipment. ONESUN analyzes customer requirements—including daily output, product type, and automation level—to configure the most suitable semi-automatic or fully automatic production line.
We provide:
Battery pack assembly lines
Cell sorting & testing machines
BMS integration systems
Aging & testing equipment
Quality inspection tools
With optimized workshop layouts and production workflows, clients can quickly achieve stable mass production and reduce operational inefficiencies.
3. Mature Product Portfolio with SKD/CKD Assembly Support
ONESUN offers a full range of proven energy storage products, including:
Residential LiFePO4 battery systems
All-in-one solar storage systems
Portable solar generators
Commercial & industrial ESS solutions
All products are market-validated across Africa, the Middle East, Southeast Asia, and Latin America. Clients can directly select from existing models and deploy local SKD (Semi Knocked Down) or CKD (Completely Knocked Down) assembly.
This localized manufacturing approach helps customers:
Avoid high import tariffs
Reduce shipping costs
Shorten delivery time
Increase local market competitiveness
Without heavy R&D investment, partners can quickly launch their own branded energy storage products.
4. Strong OEM & ODM Capabilities for B2B Clients
ONESUN specializes in OEM and ODM battery solutions for global partners. Whether you need customized battery packs, branded energy storage systems, or tailored inverter integration, we provide flexible solutions based on your market needs.
Our core strengths include:
Advanced LiFePO4 battery technology
Intelligent BMS customization
Multi-standard voltage compatibility
Product certification support (CE, IEC, UN38.3, etc.)
Branding and packaging customization
We empower distributors, project developers, and energy companies to build differentiated product lines and strengthen their market positioning.
5. End-to-End Technical Training & Long-Term Support
Technical capability is the biggest barrier for overseas factory projects. ONESUN provides a dual-direction technical support system to ensure smooth factory operation.
Clients can send engineers and managers to our China facility for hands-on training, covering:
Battery assembly processes
Equipment operation & maintenance
Quality control systems
Warehouse & material management
Production line management
In addition, ONESUN can dispatch experienced engineers to the client’s factory for on-site support, assisting with installation, debugging, trial production, and process optimization.
We also offer long-term technical updates, product upgrades, and after-sales support to ensure sustainable factory operation.
6. True Turnkey Solution: From 0 to 1 Factory Deployment
Unlike traditional suppliers that only sell equipment or components, ONESUN delivers a complete closed-loop solution:
Factory planning & design
Equipment supply & installation
SKD/CKD component supply
Technical training & staffing support
Production guidance & optimization
After-sales and lifecycle service
Even clients with zero experience can successfully build and operate a lithium battery factory.
