Model: Hanery 18650-5S4P-24000
Representing the absolute pinnacle of capacity in our 18.5V lineup, the Hanery 18650-5S4P-24000 is a true industrial-grade power station component. This massive 20-cell configuration (using ultra-high capacity 6000mAh equivalents per string) delivers an incredible 24,000mAh (444Wh). It is the definitive energy source for demanding applications like Automated Guided Vehicles (AGVs), large-scale portable lighting towers, mid-size off-grid solar generators, and heavy-duty electric mobility solutions requiring massive, sustained energy reserves.
Ultimate 24,000mAh Endurance (444Wh): The highest capacity 18.5V pack, designed for multi-day or continuous heavy-duty industrial operation.
Robust 20-Cell (5S4P) Design: Distributes extreme power loads highly efficiently across four parallel strings, maximizing the overall lifespan and safety of the battery pack.
Enterprise-Level BMS Integration: Features a highly sophisticated, high-amperage management system for precise balancing, deep thermal monitoring, and comprehensive protection against extreme fault conditions.
Superior Load Handling: The 4P parallel structure allows for significant sustained current draw with minimal voltage sag, perfect for heavy motor starting.
Industrial-Strength Construction: Built with heavy-duty enclosure materials, robust nickel busbars, and secure internal structural supports for harsh environments.
Tailored Engineering Solutions: Fully customizable dimensions, heavy-gauge wiring harnesses, and specialized high-current connectors (e.g., Anderson, XT90) for seamless integration into your large-scale equipment.
Please note that we have a MOQ for our battery. For batteries in stock, the MOQ is 10,000 pcs. For customized batteries, the MOQ is 50,000 pcs.
