18.5V 24000 mAh Lithium Batteries 18650-5S4P

18.5V 24000 mAh Lithium Batteries 18650-5S4P
  • 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.
