This 21V 6000mAh lithium-ion replacement battery pack is engineered for Dayi power tools and compatible cordless equipment, delivering reliable performance for professional and industrial applications. The pack features 15 battery cells arranged in a configuration that provides consistent voltage output across the discharge cycle. Two discharge variants are available: a 5C rated version delivering 600W power output, and a 10C rated version capable of up to 1200W for high-demand applications. The physical dimensions measure 125mm x 75mm x 79mm, making it a direct drop-in replacement for Dayi-branded battery packs.
The battery pack utilizes Lithium-Ion (Li-ion) cell chemistry, which provides excellent energy density and minimal memory effect compared to older battery technologies. USPECIAL is the brand identifier for these replacement packs, with model numbers D216005 (5C variant) and D216010 (10C variant). The 21V nominal voltage aligns with standard 18V-20V cordless tool platforms, providing sufficient headroom for demanding operations. Li-ion cells offer a typical cycle life of 500-1000 charge-discharge cycles when properly maintained, and the chemistry performs well across temperature ranges commonly encountered in workshop environments.
This product targets wholesalers, tool distributors, and OEMs seeking replacement battery inventory for the aftermarket. The 21V platform serves a large installed base of cordless power tools, making these replacement packs a high-rotation item in the trade. Typical buyers include tool repair shops, hardware distributors, and e-commerce sellers specializing in power tool accessories. The packs are shipped in standard packaging suitable for bulk ordering, and sourcing terms typically involve minimum order quantities aligned with wholesale trade practices.

Before placing an order for this battery pack, verify the exact compatibility with your target Dayi tool models by requesting dimensional drawings and connector specifications. Confirm whether you need the 5C or 10C variant based on your tools' power consumption. Request the specific cell brand and date codes to assess cell quality and freshness, as older cells may have reduced cycle life. Verify the supplier's export documentation capabilities and whether they can provide test reports for the protection circuit functionality.
Logistics considerations include confirming the lead time for production, which typically ranges 2-4 weeks for battery pack orders depending on component availability. Request the packaging dimensions and weight for accurate freight calculation. Discuss Incoterms (typically FOB Shenzhen or EXW) and payment terms, as battery products often require advance payment or letters of credit due to higher value and shipping restrictions on lithium-ion goods. Ensure the supplier provides proper UN38.3 documentation for air or sea freight.
Quality verification should include requesting sample units for testing before bulk ordering. Arrange for third-party inspection if ordering significant quantities, checking cell capacity matching, protection circuit function, and physical dimensions. Ensure documentation includes material safety data sheets (MSDS) for shipping purposes and a quality guarantee or warranty terms. Confirm the supplier can provide traceability documentation linking each pack to its cell batch for quality assurance purposes.
