18S1P 65.7V 39000mAh Semi-Solid UAV Battery | 400Wh/kg

65.7V 39Ah Semi-Solid UAV Battery Overview

65.7V 39Ah Semi-Solid UAV Battery is designed for professional drone platforms that require ultra-high energy density, higher voltage support, and lighter battery integration in an 18S architecture. With an 18S1P configuration, 65.7V 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 heavy-lift drones, industrial payload UAVs, and logistics platforms. It supports up to 0.5C charging, weighs approximately 7400g, 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 payload efficiency. Compared with bulkier conventional lithium battery formats, the 65.7V 39Ah Semi-Solid UAV Battery gives UAV manufacturers and system integrators a more advanced solution for heavy-duty drone projects that need higher voltage support and lower battery burden at the same time.

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

For heavy-lift drones, battery weight is not only a power issue, but also a payload issue. In loaded takeoff, hovering, lifting, and route-based transport tasks, a lighter high-voltage battery can improve payload margin, flight efficiency, and aircraft balance. The 65.7V 39Ah Semi-Solid UAV Battery fits this requirement well because it combines a practical 39Ah reserve with only about 7400g pack weight and an 18S high-voltage structure. That makes it suitable for heavy-lift UAV platforms that need more efficient battery packaging instead of relying on heavier conventional packs.

Suitable for Industrial Payload and Lifting Missions

This battery is especially suitable for industrial payload UAV projects where the aircraft must carry task equipment, transport materials, or operate under loaded flight conditions. In these missions, stable loaded output matters more than peak burst marketing numbers. The 65.7V 39Ah Semi-Solid UAV Battery supports this application with its 8C discharge capability, 18S voltage platform, and lightweight semi-solid structure, making it a practical option for industrial payload drones and lifting-oriented UAV systems.

Logistics UAV Applications with Better Payload Efficiency

The 65.7V 39Ah Semi-Solid UAV Battery is also highly relevant for logistics and controlled-payload UAV transport platforms. In route transport missions, operators need useful reserve for takeoff, route travel, hover allowance, and return margin without letting battery mass consume too much of the aircraft payload capacity. With 400Wh/kg high energy density, this battery helps improve endurance-to-weight performance for logistics UAVs that need higher voltage architecture and more efficient power integration.

18S High-Voltage Architecture for Heavy-Duty UAV Systems

One of the strongest advantages of the 65.7V 39Ah Semi-Solid UAV Battery is its 18S1P 65.7V architecture. Compared with lower-voltage battery systems, the 18S platform gives this model a more capable voltage level for professional UAV applications that require stronger powertrain matching, more stable loaded operation, and better system efficiency under real mission conditions. This makes the battery especially suitable for heavy-duty drone systems that need more than standard mid-voltage pack performance.

400Wh/kg Energy Density with Production-Level Practicality

The 65.7V 39Ah Semi-Solid UAV Battery combines 39Ah usable reserve with 400Wh/kg high energy density and production-level practicality. In professional UAV platforms, energy density directly affects payload margin, integration flexibility, and real sortie efficiency. A semi-solid battery with 400Wh/kg energy density can help reduce the battery weight penalty in heavy-lift and payload-focused projects while still supporting useful mission reserve.

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 65.7V 39Ah Semi-Solid UAV Battery attractive for users who need advanced energy density, reliable mass-production readiness, and better payload efficiency.

Integration Value and Structural Compatibility

With dimensions of 196(T) × 91(W) × 205(H) mm, the 65.7V 39Ah Semi-Solid UAV Battery offers strong integration value for medium and large 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, QS8, and QS9 can be considered according to project needs, while the final connector can be customized.
