14S1P 51.1V 39000mAh Semi-Solid UAV Battery | 400Wh/kg

51.1V 39Ah Semi-Solid UAV Battery Overview

51.1V 39Ah Semi-Solid UAV Battery is designed for professional drone platforms that require ultra-high energy density, higher voltage support, and extended flight time in a compact 14S architecture. With a 14S1P configuration, 51.1V nominal voltage, 39000mAh capacity, 8C discharge capability, and 400Wh/kg high energy density, this model is positioned as a high energy density semi-solid UAV battery for logistics drones, inspection UAVs, and lightweight industrial drone platforms. It supports up to 0.5C charging, weighs approximately 5600g, offers a cycle life of no less than 400 cycles, and is suitable for operating temperatures from -20℃ to 60℃.

Built on an NMC-based high energy density platform, this semi-solid UAV battery is engineered to improve the balance between usable reserve, pack weight, and aircraft efficiency. Compared with bulkier conventional lithium battery formats, the 51.1V 39Ah Semi-Solid UAV Battery gives UAV manufacturers and system integrators a more advanced solution for extended mission time and better energy-to-weight performance in endurance-focused drone systems.

Why This 400Wh/kg Semi-Solid UAV Battery Fits Logistics Drone Platforms

For logistics drones and route mission UAVs, the battery must support takeoff, route travel, payload allowance, hover margin, and return reserve without consuming too much of the aircraft weight budget. The 51.1V 39Ah Semi-Solid UAV Battery fits this requirement well because it combines a practical 39Ah reserve with a 14S higher-voltage platform and only about 5600g pack weight. That makes it suitable for route transport UAVs, compact cargo drones, and controlled-payload logistics platforms that need extended flight time and more capable voltage support than lower-series systems.

Suitable for Inspection and Mapping UAV Missions

This battery is also highly relevant for inspection, mapping, and route observation UAV platforms. In these missions, endurance-to-weight ratio often matters more than extreme burst output. A lighter battery with a useful reserve window helps improve sortie duration, route efficiency, and airframe stability. With 400Wh/kg ultra-high energy density, this semi-solid UAV battery is especially suitable for endurance-focused inspection systems and industrial drone projects that need longer usable flight time while keeping aircraft burden under better control.

Lightweight Industrial and Cleaning Drone Applications

The 51.1V 39Ah Semi-Solid UAV Battery can also support lightweight industrial drone platforms and cleaning UAV systems where stable output, practical reserve, and easier integration matter together. Because the product focuses on high energy density and reduced pack weight, it is better suited to endurance-oriented applications than to high-frequency fast-turnaround work cycles. This gives the battery clear positioning for users who care more about mission duration and aircraft efficiency than about aggressive charging speed.

14S High-Voltage Architecture with Advanced Energy Density

One of the strongest product advantages of the 51.1V 39Ah Semi-Solid UAV Battery is that it combines 39Ah usable reserve with 400Wh/kg high energy density in a 14S higher-voltage platform. Compared with lower-voltage battery systems, the 14S structure gives this model a more capable voltage level for professional UAV applications requiring better powertrain matching and more stable route-based operation. This helps the battery stand out in projects that need both lightweight integration and higher-voltage system support.

The operating temperature range of -20℃ to 60℃ improves field adaptability across wider environments, while the cycle life of at least 400 cycles gives the product practical long-term value for commercial UAV projects. This makes the 51.1V 39Ah Semi-Solid UAV Battery attractive for users who need both advanced energy density and dependable production-level performance.

Integration Value and Structural Compatibility

With dimensions of 154(T) × 91(W) × 205(H) mm, the 51.1V 39Ah Semi-Solid UAV Battery offers strong integration value for compact and medium-light UAV airframes. Its semi-solid structure and NMC-based chemistry positioning help improve packaging efficiency and energy density for advanced drone battery design. Connector selection should be evaluated according to aircraft current platform and installation structure. XT90S, AS150U, and QS8 can be considered according to project needs, while the final connector can be customized.
