14S 51.1V 39Ah 400Wh/kg High Energy Density Drone Battery

14S 51.1V Drone Battery for High Energy Density Applications

The 14S 51.1V drone battery from Herewin is designed for professional UAV systems requiring high energy density, large capacity, and lightweight construction. Featuring 39Ah capacity and 400Wh/kg cell energy density, this battery combines 1992.9Wh of nominal energy with a pack weight of approximately 5.6kg. It provides a compact power solution for endurance-focused aircraft and industrial equipment.

400Wh/kg High Energy Density Cell Technology

High energy density is one of the key advantages of this battery. With a specified cell energy density of 400Wh/kg, it helps reduce battery weight while maintaining substantial energy capacity. This is particularly valuable for UAV manufacturers working with strict takeoff weight limits, payload requirements, and flight endurance targets.

The 39Ah capacity provides considerable onboard energy in a relatively lightweight battery configuration. For aircraft designers, this creates more flexibility when balancing battery mass, payload capacity, and operating time.

14S 51.1V Drone Battery with 39Ah Capacity

Built in a 14S1P configuration, the battery delivers 51.1V nominal voltage and 39000mAh capacity, equivalent to 1992.9Wh of nominal energy. The 14S 51.1V drone battery is intended for equipment designed around a compatible 14S power system.

Its electrical specifications make it important to evaluate voltage compatibility, current requirements, and the operating limits of connected components before integration. This helps ensure the battery matches the aircraft’s propulsion system and overall power architecture.

Lightweight 5.6kg Battery Pack Design

Weighing approximately 5600g (±100g), this battery offers a balance between energy capacity and pack weight. Its dimensions are 154 × 91 × 205mm, providing a compact form factor for equipment with limited battery installation space.

For weight-sensitive applications, the 14S 51.1V drone battery allows manufacturers to evaluate a large-capacity power solution without overlooking the aircraft’s overall weight budget. Actual flight endurance will depend on propulsion efficiency, payload, power consumption, and operating conditions.

8C Discharge Rate and 0.5C Charging

The battery features an 8C rated discharge specification and a maximum charging rate of 0.5C. These performance ratings provide a reference for evaluating the battery against different UAV power requirements.

For accurate system matching, customers should confirm their continuous discharge current, peak current, and peak duration. Charging equipment must also be compatible with the battery’s specified voltage and charging limits.

≥400 Cycle Life for Professional Applications

With a specified cycle life of at least 400 cycles, this high energy density battery is designed for repeated professional operation. Cycle life is an important consideration for commercial UAV operators and industrial equipment manufacturers evaluating long-term battery usage and replacement costs.

Actual battery life depends on charging practices, discharge depth, operating temperature, and maintenance conditions.

Applications for UAVs and Industrial Equipment

The 14S 51.1V drone battery can be evaluated for long-endurance UAVs, cargo and delivery drones, agricultural drones, and aerial cleaning systems. Its high energy density and lightweight design also make this battery configuration worth evaluating for compatible industrial robots and mobile robotic platforms.

Final compatibility depends on equipment voltage, discharge current, installation dimensions, and operating requirements.
