400Wh/kg Semi-Solid UAV Battery is a high-energy-density battery developed for professional heavy-lift drones, cargo delivery UAVs, and industrial drone platforms. Featuring advanced semi-solid battery technology, an 18S1P configuration, 65.7V nominal voltage, and 39000mAh capacity, this model combines high cell-level energy density with a lightweight battery pack design for demanding UAV power applications.

400Wh/kg Semi-Solid UAV Battery Overview

The Herewin T1087187E is an 18S1P semi-solid battery designed for professional UAV platforms that require substantial energy capacity while maintaining careful control over battery weight. It delivers 65.7V nominal voltage and 39000mAh capacity, providing a high-capacity power solution for compatible industrial drone systems.

With a net weight of approximately 7400g and dimensions of 196 × 91 × 205mm, this battery is designed for UAV integration where battery mass, available installation space, and energy requirements are important engineering considerations.

Its specified cell-level energy density of 400Wh/kg is a key technology advantage. Combined with semi-solid battery technology and an 8C discharge rating, the T1087187E provides a battery option for UAV manufacturers developing lightweight, high-capacity power systems.

400Wh/kg High Energy Density Semi-Solid Technology

The 400Wh/kg Semi-Solid UAV Battery is designed around high-specific-energy cell technology. High energy density is particularly important for professional drones because battery weight directly affects aircraft takeoff weight, available payload, and overall mission planning.

For heavy-lift and cargo UAV manufacturers, improving battery energy density can help increase the amount of energy available within a given battery mass. This provides greater flexibility when balancing battery capacity, aircraft structure, payload requirements, and flight performance.

The semi-solid battery platform combines high-energy cell technology with a practical battery pack structure. It offers an additional power solution for UAV manufacturers seeking to optimize energy storage and battery integration in next-generation industrial drones.

The specified 400Wh/kg figure refers to cell-level energy density rather than the complete battery pack. Actual pack-level energy density also depends on the structural housing, electrical connections, protection components, and other pack materials.

Lightweight 39Ah Battery Design for Heavy-Lift UAVs

Battery weight is a major consideration in heavy-lift drone development. A heavier battery reduces the remaining weight allowance available for cargo, onboard equipment, and other aircraft components.

The Herewin T1087187E provides 39000mAh capacity with a net weight of 7400g (±100g). Its high-energy-density cell technology supports battery weight optimization for compatible UAV platforms.

For cargo drones and aerial lifting systems, this 39Ah battery configuration provides an energy storage option for aircraft manufacturers evaluating the relationship between battery mass, payload capacity, and required flight duration.

The compact dimensions of 196(T) × 91(W) × 205(H)mm also provide a defined installation envelope for battery compartment and aircraft structural design.

18S1P 65.7V High-Voltage UAV Battery Platform

The 400Wh/kg Semi-Solid UAV Battery uses an 18S1P configuration with a nominal voltage of 65.7V. Its high-voltage architecture is designed for compatible industrial UAV power systems.

Compared with lower-voltage battery configurations delivering equivalent electrical power, a higher nominal voltage can reduce the current required by the power system. This can help UAV engineers evaluate cable sizing, electrical losses, and power distribution requirements.

The 18S1P configuration also provides a substantial 39Ah capacity within a single-parallel-string battery architecture.

Before integration, manufacturers should verify battery voltage compatibility with motors, electronic speed controllers, power distribution components, and other onboard electrical systems.

8C Discharge Capability for Professional Drone Applications

The T1087187E features an 8C discharge rating, providing a defined discharge-performance specification for compatible professional UAV platforms.

For heavy-lift drones, the propulsion system must deliver sufficient power during takeoff, climbing, hovering, and payload transportation. Battery selection should therefore consider both energy capacity and the actual current requirements of the aircraft.

The 8C discharge rating provides a basis for evaluating this battery against the operating requirements of industrial UAV power systems. Continuous and peak current requirements should be checked against the approved battery discharge specifications before final selection.

400Wh/kg Semi-Solid UAV Battery for Heavy-Lift and Cargo Drones

Heavy-lift drones and cargo UAVs require careful coordination between battery weight, propulsion power, structural design, and payload capacity. The T1087187E offers a high-energy-density battery option for aircraft manufacturers developing aerial cargo transportation and lifting platforms.

Its 65.7V nominal voltage, 39Ah capacity, and 8C discharge rating make it suitable for evaluation in compatible heavy-lift and cargo drone systems.

For logistics applications, the battery can also be considered for delivery UAVs where energy capacity and aircraft weight influence route planning and operational efficiency.

Actual lifting capacity, flight endurance, and delivery range depend on the aircraft propulsion system, payload, aerodynamic efficiency, and mission conditions.

Battery Charging Performance and Cycle Life

The Herewin T1087187E supports a maximum charging rate of 0.5C and has a specified cycle life of at least 400 cycles.

The charging specification provides a reference for designing battery charging arrangements and fleet battery rotation schedules. For professional UAV operators, charging time, battery availability, and daily mission frequency should be considered together when planning battery deployment.

Charging equipment must be compatible with the 18S battery voltage profile and the manufacturer’s specified charging limits. Appropriate charging protection and operating procedures should be followed.

Compact Battery Structure and Custom UAV Integration

With dimensions of 196(T) × 91(W) × 205(H)mm and a net weight of 7400g (±100g), this battery provides a defined form factor for compatible industrial UAV installations.

Battery integration should consider mounting space, structural support, vibration resistance, cable routing, connector specifications, and aircraft center of gravity.

For customized UAV projects, battery configuration and electrical integration should be evaluated according to the aircraft’s voltage platform, discharge requirements, charging system, and installation conditions.
