Key Features & Advantages
400Wh/kg Ultra-High Energy Density
This ultra-high energy density significantly enhances the battery's ability to store more power in a smaller and lighter package. Compared to conventional lithium-ion batteries, it enables longer runtimes, extended range, or reduced system weight—making it especially advantageous in aerial drones, robotics, and other weight-sensitive or endurance-critical applications.
4.45V High Voltage Per Cell
By increasing the nominal voltage to 4.45V per cell, the battery delivers higher energy output and improved power efficiency compared to conventional 4.2V or 4.35V cells. This enables extended runtimes and supports high-performance applications without increasing battery size or weight.
2C Continuous / 3C Max Continuous / 5C Peak Discharge
Designed for high-load operations, enabling rapid and stable energy output.
400-Cycle Lifespan
Engineered for durability, the battery maintains reliable performance over 400 full charge-discharge cycles under standard usage conditions.
Versatile and Adaptable
With its high energy density, stable discharge, and compact form factor, this battery fits seamlessly into a variety of demanding applications across industries—from aerial drones and ground robots to portable power systems and field equipment.
