12S1P 43.8V 39000mAh Semi-Solid UAV Battery | 400Wh/kg

43.8V 39Ah Semi-Solid UAV Battery Overview

43.8V 39Ah Semi-Solid UAV Battery is designed for professional drone platforms that require ultra-high energy density, lightweight battery integration, and extended flight time in a 12S LiHV architecture. With a 12S1P configuration, 43.8V 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 cleaning drones, logistics UAV platforms, and lifting-oriented drone applications. It supports up to 0.5C charging, weighs approximately 4800g, 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, the 43.8V 39Ah 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 43.8V 39Ah Semi-Solid UAV Battery offers a more efficient energy-to-weight solution for UAV platforms that prioritize endurance, stable cruising, and lightweight system integration over aggressive heavy-load burst discharge.

Why the 43.8V 39Ah Semi-Solid UAV Battery Fits Cleaning Drone Platforms

For cleaning drone systems, battery weight has a direct effect on hovering efficiency, maneuverability, and practical task continuity. The 43.8V 39Ah Semi-Solid UAV Battery fits this requirement well because it combines a practical 39Ah reserve with only about 4800g pack weight, helping UAV integrators achieve better endurance-to-weight performance in façade cleaning, roof cleaning, and similar route-based cleaning tasks.

The 12S LiHV structure also gives the 43.8V 39Ah Semi-Solid UAV Battery stronger voltage support than lower-voltage packs, making it suitable for professional cleaning drones that need smoother continuous output and higher energy density in a compact battery format.

Suitable for Logistics UAV Platforms Requiring Stable Cruising

The 43.8V 39Ah Semi-Solid UAV Battery is also highly relevant for logistics UAV platforms, especially route-based transport drones that need practical reserve, lower battery burden, and efficient continuous flight. In these missions, battery performance is not only about capacity, but also about how effectively that capacity is packaged into the airframe. With 400Wh/kg high energy density and a 4800g lightweight structure, the 43.8V 39Ah Semi-Solid UAV Battery supports better route efficiency and improved load-to-battery balance in compact logistics applications.

Lifting-Oriented UAV Applications

This battery can also support lifting-oriented UAV platforms where efficient battery weight control is important. Because the 43.8V 39Ah Semi-Solid UAV Battery is based on an 8C low continuous discharge platform, it is more suitable for endurance-focused loaded operation than for extreme instantaneous high-thrust lifting conditions. That makes it a practical option for moderate lifting and payload-carrying missions where stable cruising output and lower battery burden are more important than maximum burst discharge.

400Wh/kg High Energy Density for Lightweight UAV Integration

One of the strongest product advantages of the 43.8V 39Ah Semi-Solid UAV Battery is its 400Wh/kg high energy density. In professional drone systems, energy density directly affects aircraft weight, payload margin, installation flexibility, and real sortie efficiency. A semi-solid battery with 400Wh/kg energy density helps reduce the battery-weight penalty while still maintaining a useful reserve window for real working conditions.

The cycle life of at least 400 cycles gives the 43.8V 39Ah Semi-Solid UAV Battery practical long-term value, while the -20℃ to 60℃ operating range supports broader field deployment across varying environments. This makes it especially suitable for commercial UAV users who need a more advanced endurance-focused battery with production-level practicality.

Charging Logic and Application Positioning

The 43.8V 39Ah Semi-Solid UAV Battery supports only 0.5C charging, which means it is better suited to scheduled charging workflows rather than urgent fast-turnaround operations. This battery should be positioned as a high energy density long-endurance solution for cleaning, logistics, and lifting-oriented UAV platforms, rather than as a fast-charge or burst-heavy battery for extreme high-load applications.

Compact Integration and Matching Recommendations

With dimensions of 132(T) × 91(W) × 205(H) mm, the 43.8V 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.
