Sourcing
Industrial Batteries & Energy Storage Systems Sourcing
Send a private RFQ for BESS, lithium and lead-acid batteries. Specify chemistry, capacity, voltage, cycle life, BMS and the transport documents (e.g. UN 38.3) you need.
Energy Storage & Batteries sourcing guide
B2B Sourcing Guide: Energy Storage Systems & Industrial Batteries
Energy storage buyers range from solar EPC contractors and telecom operators to forklift fleet owners, UPS integrators and distributors. Each needs a different chemistry, capacity and level of documentation. On BIGEXPORT you describe your requirement once in a private Request for Quotation (RFQ); your request is not published in a public list, and it is shared only with suppliers matched to the category and specification.
Main battery types
- Lithium iron phosphate (LiFePO4 / LFP): long cycle life and good thermal stability; widely used in stationary storage, solar and telecom backup.
- Lithium NMC / NCA: higher energy density; typical for mobility and compact systems.
- Lead-acid (AGM, gel, flooded, OPzS/OPzV): lower upfront cost; common in UPS, telecom and traction applications.
- Other technologies: nickel-based cells, sodium-ion and flow batteries for specific projects.
Energy storage systems
Beyond individual cells and modules, buyers source complete systems: residential storage units, commercial and industrial (C&I) cabinets, containerised battery energy storage systems (BESS), rack batteries for data centres and UPS, and portable power stations. Clarify whether you need cells only, battery packs with BMS, or a turnkey system with inverter/PCS, EMS and fire protection.
Typical applications
- Solar and hybrid systems, peak shaving and grid support
- Telecom base stations and data-centre backup
- Material handling, golf carts and light electric vehicles
- Marine, RV and off-grid installations
Technical purchasing criteria
- Chemistry, nominal voltage and usable capacity (kWh / Ah)
- Cycle life at a stated depth of discharge and temperature
- Charge/discharge rate (C-rate) and round-trip efficiency
- BMS functions, communication protocols (CAN, RS485, Modbus) and inverter compatibility
- Operating temperature range, IP rating and cooling method
- Warranty terms, capacity retention and after-sales support
Certifications and safety documents
Requirements depend on the destination market, application and transport mode, so confirm them with your local authority or advisor. Documents buyers frequently request include UN 38.3 test reports and safety data sheets for shipping lithium batteries, IEC 62619 or IEC 62133 for cell and battery safety, UL 1973 / UL 9540 for certain stationary systems, and CE or other regional conformity marks. Ask suppliers for valid test reports from recognised laboratories rather than relying on claims alone.
International sourcing process
Lithium batteries are generally treated as dangerous goods in transport. Agree on Incoterms, packaging class, state of charge for shipment, HS code, lead time and inspection before shipment. For larger projects, consider a sample or pilot order and a third-party factory audit.
How to prepare an effective RFQ
- Application and installation site
- Chemistry, voltage, capacity and quantity
- Required documents and target market
- Delivery country, Incoterms and target timeline
A clear RFQ helps BIGEXPORT match your request with suitable suppliers. Quotes and response times depend on supplier availability; there is no guarantee of a specific number of offers.
