11.1V 12000 mAh Lithium Batteries 21700-3S3P

When raw, sustained power is just as critical as massive capacity, the Hanery 21700-3S3P-12000 is the ultimate high-voltage core. Utilizing nine high-discharge 4000mAh cells in a 3S3P configuration, this pack delivers an incredible 12,000mAh (133.2Wh) at 11.1V. By distributing the electrical load across three parallel strings, this pack boasts ultra-low internal resistance, minimizing voltage sag and heat generation even when driving the most powerful motors. It is the definitive energy source for large-scale robotics, heavy-duty AGVs, and high-wattage industrial equipment requiring massive, sustained energy delivery.

  • Extreme 12,000mAh Reserve: The definitive high-endurance solution for demanding 11.1V industrial applications.

  • High-Drain Optimized (3S3P): Designed specifically to handle massive continuous discharge currents safely and efficiently.

  • Superior Load Sharing: Distributing the current across 3 parallel strings drastically reduces stress and heat on individual cells, maximizing lifespan.

  • Ultra-Low Internal Resistance: Ensures maximum power is delivered to your device’s motors or electronics, not wasted as heat within the pack.

  • Advanced Fleet-Grade BMS: Integrates a sophisticated management system for precise 3-node balancing, deep thermal monitoring, and comprehensive high-current protection.

  • Ruggedized Construction: Built with heavy-gauge pure nickel busbars and robust structural supports to withstand the physical demands of heavy industrial use.
