Technical Specifications of the 51.8V 33600mAh Agriculture Drone Battery Pack

Voltage and Configuration
The 51.8V 33600mAh Agriculture Drone Battery Pack is built with a 14s8p cell configuration, meaning 14 cells are connected in series and 8 in parallel. This arrangement provides a nominal voltage of 51.8V, striking the right balance between high efficiency and reliable power output. The higher nominal voltage reduces current draw, which in turn lowers heat generation and energy loss, making the battery ideal for long-duration agricultural drone missions. With its optimized structure, drones can execute heavy-duty tasks such as spraying, mapping, or seeding with stable power delivery, minimizing the risk of fluctuations that could disrupt performance during critical operations.

Capacity and Runtime
With a capacity of 33,600mAh, this battery pack offers drones the ability to fly for significantly longer durations compared to standard alternatives. For agricultural operators, this means larger sections of farmland can be covered in a single flight, reducing downtime caused by frequent battery swaps. Extended runtime is especially valuable during time-sensitive operations like pesticide spraying, where efficiency and speed directly impact crop health and yield. The high-capacity design also reduces the number of batteries needed to sustain long workdays, ultimately saving costs and streamlining field logistics.

High Discharge Rates
Engineered for demanding payloads, the 51.8V 33600mAh battery supports a continuous discharge current of 300A and a peak discharge current of 370A. These powerful ratings ensure that drones can easily handle heavy agricultural equipment, such as large spraying tanks, seeding modules, and advanced multispectral imaging cameras. The ability to maintain strong discharge rates under load reduces the risk of power drops, allowing drones to maintain consistent thrust and flight stability. This makes the battery a dependable energy source for both standard agricultural drones and high-performance UAVs designed for industrial-scale farming.

Safety Features
Safety and longevity are integral to the design of the 51.8V 33600mAh Agriculture Drone Battery Pack. The pack includes a failsafe trigger at 44.8V, which prevents deep discharge that could permanently damage the cells. The minimum flying voltage of 40.6V ensures that drones land safely before critical power depletion occurs. Additionally, the integrated cell balancing system maintains uniform charge distribution across all cells, reducing the risks of overheating, cell imbalance, or voltage instability. Together, these features not only protect the battery but also extend its usable lifespan, making it a safe and cost-effective investment for long-term agricultural operations.


Performance and Reliability Features

Stable Voltage Output

The 51.8V 33600mAh Agriculture Drone Battery Pack is designed to deliver stable and consistent voltage throughout its entire discharge cycle. Unlike traditional batteries that experience sharp voltage drops under heavy loads, this pack ensures smooth power delivery. This feature is especially valuable for drones performing precision tasks such as spraying pesticides, spreading fertilizer, or conducting multispectral imaging. Consistent voltage output helps maintain flight stability, accurate GPS navigation, and precise spraying patterns, which ultimately improves productivity and reduces resource wastage.

Long Cycle Life

One of the standout characteristics of this agriculture drone battery pack is its extended cycle life. It has been engineered to endure more than 500 charging cycles while retaining up to 80% of its original capacity. This makes it an economical choice for farmers and commercial drone operators who rely on consistent performance over long periods. Fewer replacements mean reduced operational costs, less downtime, and more sustainable farming practices. When compared to Li-Po batteries, which degrade faster and often require early replacement, this Li-ion pack provides long-term reliability and superior return on investment.

High-Quality Connectors

For safe and efficient operation, the battery pack is equipped with Amass AS150U discharge connectors and JST XH charging interfaces. These high-quality connectors play a crucial role in ensuring reliable energy transfer between the battery and the drone’s power system. By minimizing resistance and heat generation, they safeguard the battery against potential damage and enhance overall performance. Additionally, their universal design allows compatibility with a wide range of agricultural drone systems, making installation and maintenance more convenient. The secure connections also reduce the risks of short circuits, overheating, or power interruptions during flight, which is critical when drones are carrying expensive payloads or operating in harsh field environments.


Comparison with Traditional Li-Po Batteries

Energy Density

The 51.8V 33600mAh Agriculture Drone Battery Pack is designed with superior energy density compared to conventional Li-Po batteries. With its higher Wh/kg ratio, it delivers more power without adding unnecessary weight to the drone. This balance between stored energy and overall mass directly translates to longer flight durations, enabling drones to cover larger areas in fewer missions. For agricultural operators, this means more efficient spraying, seeding, or surveying without the frequent need to swap batteries. Higher energy density also improves payload efficiency, allowing drones to carry heavier tanks, sensors, or mapping devices without sacrificing endurance.

Temperature Performance

One of the major limitations of Li-Po batteries is their vulnerability to extreme weather conditions. They often lose efficiency in cold environments and risk overheating in hot climates. The 51.8V 33600mAh Agriculture Drone Battery Pack, built with high-quality Li-ion cells, overcomes these challenges. It performs reliably across a wide operating temperature range of -20°C to +60°C, ensuring stable drone operations year-round. Farmers in cold northern regions or hot tropical zones can depend on this pack to maintain consistent performance, avoiding unexpected downtimes caused by temperature-related power drops. This resilience makes it an all-weather solution for agricultural drone missions.

Safety and Maintenance

Li-Po batteries are known to suffer from issues such as swelling, puffing, or even leaking after repeated charge-discharge cycles. These structural failures not only reduce lifespan but also pose safety risks during flight. In contrast, the 51.8V 33600mAh Agriculture Drone Battery Pack is engineered with robust Li-ion technology that maintains structural integrity over time. It eliminates the common problems of puffing and bulging, reducing downtime and minimizing maintenance requirements. This means fewer replacements, lower costs, and greater confidence in the field. For large-scale farming operations, the reduced need for constant monitoring and frequent servicing translates to significant time and cost savings.


Applications of the 51.8V 33600mAh Agriculture Drone Battery Pack

Agricultural Spraying

One of the most important uses of the 51.8V 33600mAh Agriculture Drone Battery Pack is powering spraying drones that carry pesticides, herbicides, and fertilizers.
