MASON POWER 650Wh/kg 3.85V 30000mAh Anode-Free Battery Cell – 115.5Wh for Long-Endurance UAVs

650Wh/kg Ultra-High Energy Density: Industry-leading gravimetric density enables extended flight times and significant system weight reduction.

115.5Wh Usable Energy in 189g: 36% more capacity than the 22Ah version at the same energy density – ideal for larger, longer-endurance platforms.

Wide 2.5 – 4.5V Operating Range: Maximum system design flexibility; broad voltage window ensures usable energy across diverse operating conditions.

1C Continuous / 3C Burst Discharge: Optimized for long-endurance missions where energy capacity is prioritized over peak power.

Manufacturing Excellence: Backed by Dongguan Maosheng New Energy's fully automated, ISO-certified production infrastructure with 100% traceability.

Key Features

  • Ultra-Precision Electrode Assembly: Sub-millimeter alignment accuracy in our automated stacking and winding lines ensures flawless electrode spacing – critical for anode-free designs where uniformity directly impacts cycle stability and safety.
  • 100% Formation & Grading: Every cell undergoes comprehensive formation cycling and precision grading for capacity, ACIR, and self-discharge rate – with sorting tolerances that guarantee consistent performance across every production batch.
  • Proven Quality Systems: Our manufacturing facilities maintain ISO 9001, UL, and UN38.3 certifications, ensuring that every anode-free cell meets the strictest international safety and reliability standards for global shipment.
