This 21V 4000mAh 18650 lithium battery pack is a high-discharge power solution engineered as a direct replacement for Worx cordless power tools. The pack operates at 21V DC nominal voltage and delivers 420W continuous power with a 5C discharge rate in the standard model MY-214005W, while the high-output variant MY-214010W produces 840W at 10C discharge rate. The battery module incorporates 10 premium 18650 lithium-ion cells arranged in a configuration providing substantial capacity for extended tool operation, housed in a compact 115mm × 74mm × 64mm form factor.
The battery pack utilizes 18650 format cells, which are cylindrical lithium-ion cells measuring 18mm diameter and 65mm length, widely used in professional power tool applications. The 10-cell arrangement provides a nominal energy capacity of approximately 84Wh, representing the highest capacity option in this product line and enabling significantly longer runtime between charges compared to lower capacity alternatives. The pack features a composite housing incorporating both lithium-ion cells and nickel-metal hydride structural elements.
This product targets B2B buyers sourcing replacement batteries for the professional tool resale and after-market sectors. The Worx-compatible design ensures broad applicability across the Worx 21V cordless tool range, offering end users a cost-competitive alternative to branded original equipment batteries. The supplier indicates OEM branding options are available for qualified buyers, supporting private-label distribution strategies for distributors and importers serving hardware, construction supply, and industrial tool markets.

Buyers should conduct thorough supplier verification before placing orders, including confirmation of business registration and harbor trust tier status. Request detailed specifications for the 18650 cells including manufacturer brand, cell model, and certification status. Since this is a trading company, obtain documentation identifying the actual manufacturing facility. Request sample units for capacity verification and mechanical fit testing with target tools before committing to bulk orders.
Confirm logistics and commercial terms explicitly before order placement. Lead times for high-capacity battery packs typically range from 25-40 days depending on order volume and production scheduling. Request comprehensive quotes covering product price, packaging, labeling, freight costs, and applicable incoterms (FOB, CIF, or DDP). Negotiate payment terms appropriate for your relationship history with the supplier, typically involving advance payment or letter of credit for new accounts.
Quality assurance for high-capacity lithium-ion battery packs requires rigorous pre-shipment inspection by qualified third-party inspectors. Key verification points include actual capacity testing under load (not just nominal ratings), voltage accuracy across the discharge curve, protection circuit function testing, and visual inspection for housing defects and cell alignment. Request UN38.3 test reports for transportation compliance and IEC 62133 safety documentation. Establish detailed quality specifications in the purchase agreement with clear acceptance criteria and procedures for handling non-conforming units.
