Featuring a 6S1P configuration, 22.8V nominal voltage, 21000mAh capacity, and 25C discharge rate, it delivers a practical combination of power output, fast-charging capability, and repeated-use performance.

With a maximum charging rate of 5C and a rated cycle life of 600 or more cycles, this battery is designed for demanding drone operations where charging turnaround and dependable power delivery matter. Its soft-pack construction, 2620g net weight, and compact dimensions make it an option for compatible drone platforms requiring a 6S power system.

25C High-Rate Discharge for Demanding Drone Operations

The 21Ah 25C Drone Battery is designed for UAV applications requiring higher discharge capability than standard low-rate battery systems. Its 25C discharge rating makes it suitable for evaluating on aircraft with demanding propulsion requirements, subject to the battery’s approved current limits and operating conditions.

For agricultural drones, FPV aircraft, and training platforms, battery selection should consider motor power, propeller configuration, flight weight, peak current demand, and the required flight duration. Matching these factors helps ensure that the battery meets the aircraft’s actual operating requirements.

5C Fast Charging for Reduced Turnaround Time

Frequent flight operations can require multiple battery sets and an efficient charging workflow. The Herewin 21Ah 25C Drone Battery supports a maximum charging rate of 5C, offering a fast-charging option for compatible battery systems.

The permitted charging rate must follow the approved battery specifications and charging procedure. Actual charging time depends on the starting state of charge, charger output, battery temperature, and charging profile.

For agricultural operations and drone training programs, a suitable charging setup can help coordinate battery rotation and reduce unnecessary waiting between flights.

Soft-Pack Design for Agricultural Drones

Agricultural drones are used for crop spraying, field monitoring, and other repetitive aerial tasks. These applications require batteries that match the aircraft’s voltage, discharge requirements, payload, and expected operating duration.

The 21Ah 25C Drone Battery provides a 6S1P, 22.8V power configuration with 21000mAh capacity. Its soft-pack design offers an alternative for compatible agricultural UAV platforms where battery dimensions, weight, and electrical performance are important selection criteria.

Before installation, confirm the battery compartment, connector, operating current, and required flight endurance with the aircraft manufacturer.

FPV Drone Battery for Responsive Power Delivery

FPV drones can require substantial current during acceleration and demanding flight maneuvers. A suitable battery must balance discharge capability, capacity, weight, and compatibility with the propulsion system.

With its 25C discharge rating and 21Ah capacity, this soft-pack battery can be evaluated for compatible FPV platforms designed around its 6S1P, 22.8V configuration. Actual suitability depends on the aircraft design and its continuous and peak current requirements.

Drone Training Battery for Repeated Flight Operations

Drone training programs often involve repeated takeoffs, landings, flight exercises, and practical operation sessions. Battery reliability and an efficient charging workflow are important for organizing these activities.

The Herewin 21Ah 25C Drone Battery has a rated cycle life of at least 600 cycles. Combined with its maximum 5C charging rate, it provides a battery option for compatible training aircraft that require repeated use and suitable charging turnaround.

Actual cycle life depends on charging conditions, depth of discharge, operating temperature, discharge current, and battery maintenance.

Compact 6S1P Battery Specifications

The battery features a nominal voltage of 22.8V, a capacity of 21000mAh, and a calculated nominal energy of 478.8Wh. Its net weight is 2620g (±100g), with dimensions of 73(T) × 109(W) × 189(H) mm.

These specifications allow drone manufacturers and operators to evaluate the battery against available installation space, total aircraft weight, power demand, and target flight duration.
