A New Breakthrough in Drone Batteries: Extended Endurance with the 46-Series Large Cylindrical Battery

1. Ultra-High Energy Density & Lightweight Design

The 46-series offers energy densities ranging from 335 Wh/kg to 380 Wh/kg, with a maximum capacity of up to 84,000 mAh. Compared to traditional battery solutions, it provides higher energy capacity at lower weight and smaller volume, optimizing drone performance.

2. Low Internal Resistance, High Discharge Efficiency

With an internal resistance (IR) below 1.5 mΩ, the battery generates minimal heat during high-current discharge and maintains excellent performance across different load resistances (RL). This not only improves discharge efficiency but also enhances the battery’s durability and safety.

3.2C–4C Continuous (8C Peak) Discharge

Thanks to the battery, drones can achieve faster climbs, higher-speed flight, and better resistance to strong winds, while performing more agile maneuvers during missions. Even for heavy-lift drones during rapid ascent or high-speed flight, the battery can continuously deliver stable energy output, meeting high-power load demands with greater safety margin.

Although originally developed for KEEL series drones, this battery’s exceptional performance also makes it suitable for other high-end applications:

UAVs: VTOL fixed-wing drones, large hexacopters, quadcopter agricultural drones, logistics drones, mapping drones, etc. Robotics: High-performance warehouse robots, security patrol robots, special-purpose industrial robots. Aerial Work Platforms: Personal flying devices such as powered paragliders and jetpacks High-End Power Tools: Equipment requiring long-duration, high-power output Energy Storage Systems: Outdoor portable power stations, residential energy storage, and similar applications
