400Wh/kg High Energy Density UAV Battery for Long-Endurance Applications
400Wh/kg Drone Battery for Long-Endurance UAV Applications
The 400Wh/kg drone battery from Herewin is designed for UAV platforms where energy density, battery weight, and available capacity are critical. Featuring a 12S1P configuration, 43.8V nominal voltage, and 39000mAh capacity, this battery delivers 1708.2Wh of nominal energy in a compact 4.8kg pack. It is suitable for evaluating long-endurance drones, cargo UAVs, agricultural drones, aerial cleaning systems, and industrial robotics.
High Energy Density Battery Technology
With a specified energy density of 400Wh/kg at the cell level (subject to technical confirmation), this battery is developed for applications that require more energy within a limited weight budget. High energy density cell technology helps UAV designers optimize the balance between onboard energy, aircraft weight, and payload capacity.
For professional drone manufacturers, reducing battery mass can create more flexibility in aircraft design. It can help preserve payload allowance, support endurance-oriented configurations, and provide additional options when developing lightweight power systems.
Lightweight 39Ah UAV Battery with 43.8V Output
This 12S 43.8V 39000mAh battery combines a large capacity with a pack weight of approximately 4.8kg. Its nominal energy reaches 1708.2Wh, making it a practical candidate for UAV platforms that require substantial onboard energy without an unnecessarily heavy battery configuration.
The compact dimensions of 132 × 91 × 205mm also provide a reference for aircraft manufacturers evaluating battery compartment layouts, mounting structures, and overall system integration.
Long Endurance Drone Battery for Extended Missions
Long-endurance UAV platforms require careful management of energy capacity and total aircraft weight. A lightweight, high-capacity battery can support aircraft designers in optimizing flight duration while maintaining the required payload and propulsion performance.
This 39Ah battery is suitable for evaluating long-endurance applications such as aerial inspection, transportation, agricultural operations, and other professional UAV missions. Actual flight time depends on aircraft power consumption, payload, propulsion efficiency, operating conditions, and usable battery capacity.
Cargo Drone Battery for Lightweight Transportation Platforms
Cargo drones need to balance battery energy, payload capacity, and flight range. Excessive battery weight can reduce the available payload allowance, while insufficient energy capacity can limit the distance and duration of transportation missions.
The Herewin 12S 39Ah battery offers a lightweight power option for compatible cargo UAV platforms. Its 43.8V voltage configuration and 1708.2Wh nominal energy can be evaluated according to the aircraft’s propulsion system, transportation load, and route requirements.
Agricultural Drone Battery for Professional Field Operations
Agricultural UAVs require reliable power for repeated field missions, including spraying, crop monitoring, and precision agriculture operations. Battery weight, energy capacity, and discharge capability all influence the aircraft’s operating efficiency.
This high energy density agricultural drone battery can be considered for compatible lightweight agricultural platforms where battery mass and available energy are important selection factors. Its 39Ah capacity provides a substantial energy reserve for aircraft designers planning their power systems around a 12S platform.
Cleaning Drone Battery for Aerial Cleaning Systems
Aerial cleaning drones often operate with additional equipment and require sufficient power for extended hovering and controlled flight. Battery selection must account for the aircraft’s total weight, cleaning equipment, propulsion requirements, and operating duration.
With its lightweight 4.8kg pack design and 39Ah capacity, this battery can be evaluated for suitable aerial cleaning platforms. Manufacturers should verify the required operating current, installation dimensions, and electrical compatibility before integration.
High Energy Density Battery for Industrial Robots
Battery weight and energy capacity are also important in mobile robotics, where available installation space and operating time can directly influence system design. Lightweight battery solutions can be valuable for mobile platforms that require extended operating periods without increasing their overall weight.
The 43.8V 39Ah configuration can be evaluated for compatible industrial robots and mobile robotic systems. Applications may include autonomous mobile robots and other equipment designed around a suitable 12S lithium battery platform. Final compatibility depends on voltage requirements, discharge current, battery dimensions, and communication or protection requirements.
8C Discharge Capability and 0.5C Charging
This battery has a rated discharge capability of 8C and supports a maximum charging rate of 0.5C. These specifications provide a starting point for evaluating power requirements and charging arrangements for the target aircraft or robotic platform.
For accurate battery matching, customers should confirm their continuous current, peak current, peak duration, and charging requirements. The specified cycle life is at least 400 cycles. Actual service life depends on operating conditions, charging practices, temperature, and depth of discharge.
