Its specified 400Wh/kg cell-level energy density is one of its main technological advantages. Combined with an 8C discharge rating and semi-solid battery technology, the T1290190EF provides an energy storage solution for professional UAV applications where battery energy and pack integration are important design considerations.

400Wh/kg High Energy Density Semi-Solid Battery Technology

The 43.8V 41Ah 400Wh/kg Semi-Solid UAV Battery features high-specific-energy cell technology with a specified energy density of 400Wh/kg. Energy density is an important factor in professional UAV development because battery mass directly affects aircraft takeoff weight, payload allowance, and flight endurance.

By using high-energy-density semi-solid cells, UAV manufacturers can evaluate more flexible battery configurations when balancing onboard energy, battery mass, and aircraft structure.

The semi-solid battery platform combines advanced cell technology with a practical battery pack structure, providing an energy storage option for manufacturers developing next-generation industrial drones.

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

41Ah High-Capacity Battery for Professional UAV Platforms

Battery capacity is an important consideration in professional UAV design. A high-capacity battery provides substantial stored energy for aircraft propulsion and onboard electrical systems.

The Herewin T1290190EF provides 41000mAh capacity with a net weight of 5050g (±100g). Its 12S1P configuration offers a high-capacity power option for compatible industrial UAV platforms.

With dimensions of 151(T) × 94(W) × 216(H)mm, this model provides a defined installation envelope for aircraft battery compartments and mounting structures.

For UAV manufacturers, selecting the appropriate battery structure is important when evaluating available installation space, mounting arrangements, cable routing, and aircraft center of gravity.

12S1P 43.8V UAV Battery Configuration

The T1290190EF uses a 12S1P configuration with a nominal voltage of 43.8V. This battery architecture is designed for compatible UAV propulsion and power distribution systems.

A suitable voltage platform is essential when matching batteries with motors, electronic speed controllers, and onboard electrical components. The 12S1P configuration provides a defined electrical specification for UAV manufacturers developing compatible power systems.

With 41Ah capacity, this battery provides substantial energy storage within a single-parallel-string configuration.

Before integration, manufacturers should verify compatibility with the aircraft’s motor system, ESC voltage limits, power distribution components, and charging equipment.

8C Discharge Performance for Professional UAV Systems

The Herewin 43.8V 41Ah 400Wh/kg Semi-Solid UAV Battery features an 8C discharge rating, providing a defined discharge specification for compatible professional drone platforms.

For industrial UAVs, battery selection should consider both stored energy and the actual current requirements of the propulsion system. Takeoff, climbing, hovering, and payload operations can create different power demands throughout a flight mission.

The 8C discharge rating provides a reference for evaluating this battery against professional UAV power requirements. Actual continuous and peak current limits should be verified against the approved battery discharge specifications.

Battery Dimensions and UAV Installation Flexibility

Battery dimensions and structural design are important factors in UAV integration. Different aircraft platforms may require different battery compartment sizes, mounting positions, and weight distributions, even when their electrical requirements are similar.

The T1290190EF features dimensions of 151(T) × 94(W) × 216(H)mm and a net weight of 5050g (±100g). This configuration provides an alternative installation size within the Herewin 41Ah semi-solid battery series.

Before selecting a battery, UAV manufacturers should evaluate available installation space, mounting points, vibration resistance, cable routing, and aircraft center of gravity.

Long-Endurance and Industrial UAV Battery Applications

Professional UAV platforms require careful optimization of battery capacity, aircraft weight, propulsion efficiency, and mission requirements.

The T1290190EF combines 41Ah capacity with 400Wh/kg cell-level energy density, providing an energy storage option for compatible industrial and long-endurance UAV systems.

Its 43.8V voltage platform and 8C discharge rating can be evaluated for professional multi-rotor drones and other industrial UAV configurations designed around a compatible 12S battery system.

Actual flight endurance and payload capacity depend on aircraft configuration, aerodynamic efficiency, propulsion performance, payload weight, and operating conditions.

Battery Charging Performance and Cycle Life

The Herewin T1290190EF supports a maximum charging rate of 0.5C and has a specified cycle life of at least 300 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.

Charging equipment must support the correct 12S battery voltage profile and the manufacturer’s specified charging limits. Appropriate charging protection and operating procedures should always be followed.

Custom Semi-Solid UAV Battery Integration

For customized UAV projects, battery selection involves more than voltage and capacity. Pack dimensions, weight, discharge requirements, connector specifications, mounting arrangements, and charging compatibility must all be considered.

Herewin provides UAV battery solutions for professional drone manufacturers requiring different voltage platforms, capacities, and battery pack structures.
