The DJI Agras T100 represents a major leap in agricultural drone technology, combining immense power, precision, and adaptability for large-scale crop management. From its 100-liter liquid tank to advanced LiDAR-based terrain following, the T100 is designed for professional farmers and agronomists seeking efficiency and reliability in aerial spraying.
This in-depth analysis brings together real field tests from Brazil, the U.S., and China, uncovering what the Agras T100 can truly deliver — and whether it’s worth the upgrade from the T70 or T60X.
What Is the DJI Agras T100?
The Agras T100 is DJI’s latest flagship agricultural spraying drone, succeeding the T70 and T60 series. It is built to handle high-volume spraying, seeding, and fertilization tasks for crops such as rice, soybeans, citrus, and wheat.
Key Highlights
The payload capacity of up to 100 L for liquid or 150 L for solid material immediately places this platform in the top tier of agricultural or industrial spraying drones. In real-world operations, that kind of capacity dramatically reduces refill cycles, which is often more important than raw flight time. However, with a maximum takeoff weight of 149 kg, this is clearly a machine that demands strict safety protocols, trained operators, and compliant airspace management.
The 41,000 mAh battery, rated for roughly 1,500 charge cycles, suggests long-term operational planning rather than casual use. Even though the flight time under full load is only around 6–8 minutes, that’s actually expected for a drone carrying this much mass. What matters more is efficiency during those minutes, and the spray width of up to 11 meters shows that the system is optimized to work fast and wide.
With a top speed of 72 km/h, the drone can reposition quickly between plots, but in practice, most spraying would happen at lower, more controlled speeds to maintain accuracy. The real performance highlight is the coverage rate of roughly 5–6 hectares per flight, which is impressive given the short airtime. This indicates a design philosophy focused on high-impact, short-duration missions rather than long loiter times.
This drone is built for professional-scale operations—large farms, plantations, or industrial applications—where speed, payload, and coverage efficiency matter far more than flight duration. It’s not about staying in the air longer; it’s about getting as much work done as possible in every single flight.

Design and Build Quality
The Agras T100 looks and feels like a flying helicopter — robust, powerful, and built for demanding agricultural conditions.
- Structure: Four arms, eight coaxial motors, and carbon fiber
- Modular Tank System: Users can quickly swap between liquid and granular tanks via a 4-latch system.
- Enhanced Cooling System: Battery sits at the front, using airflow during flight to reduce heat.
- Foldable Frame: Locking mechanisms ensure tight arm joints even after 20,000+ acres of use.
Its build quality is pure DJI — rugged yet intuitive, minimizing assembly and maintenance time in the field.
Based on typical agricultural drone benchmarks:
– Coverage: ~10–15 hectares per hour (depending on terrain)
– Battery cycle: ~10–15 minutes per flight
– Operational efficiency: significantly higher than manual sprayingThese numbers can vary depending on crop type and conditions.
A Typical Use Case Scenario: In a real-world workflow, a farming team might use multiple battery cycles throughout the day to cover large fields. The drone operator focuses on route planning and monitoring, while automation handles the spraying process. This significantly reduces manual labor while maintaining consistency.
Intelligent Sensing and Flight Precision
The Agras T100 integrates LiDAR, radar, and vision sensors for full 360° environmental awareness.
- LiDAR Sensor: Emits 30,000 pulses/second for centimeter-level terrain mapping.
- FPV Camera: Fixed wide-angle fisheye for real-time monitoring.
- Obstacle Avoidance: Multi-sensor fusion ensures safety around trees, slopes, and uneven terrain.
- Terrain Following: Exceptional hill and slope tracking performance, maintaining constant spray height even at max speed.
Field tests in hilly terrain confirmed that the terrain-following system works flawlessly — climbing, descending, and adjusting spray patterns dynamically.
Real-World Performance Test
During multiple test flights in Brazil’s rice fields:
- Load: 82 liters of liquid pesticide
- Flight Duration: 6 minutes 19 seconds
- Area Covered: 5.72 hectares
- Remaining Battery: 14%
- Spray Height: 5 meters above crop canopy
At 72 km/h, the drone maintained stable flight and spray uniformity.
However, with a full 100L tank, flight endurance decreases — suggesting an optimal payload of 65–70L for best battery efficiency.
Compared with other spraying methods:
| Method | Speed | Coverage per Hour |
|---|---|---|
| Self-propelled sprayer | 15 km/h | ~40 ha/h |
| Agricultural aircraft (Embraer 202) | 180 km/h | ~80 ha/h |
| DJI Agras T100 | 72 km/h | ~55–60 ha/h (average) |
While not replacing aircrafts in raw capacity, the T100 offers unmatched precision, flexibility, and automation — ideal for medium to large farms.
In practical use, agricultural drones like the Agras T100 can:
- Cover large areas significantly faster than manual spraying
- Reduce labor costs
- Improve consistency in pesticide application
However, efficiency depends heavily on operator skill, terrain, and weather conditions.
Battery and Power Efficiency
Each Agras T100 battery weighs 14.7 kg and provides around 6–8 minutes of heavy-load flight.
- Recharge cycle: ~15–18 minutes using the DJI charging dock.
- Expected lifespan: 1,200–1,500 cycles.
The energy-to-weight ratio is optimized to balance endurance and payload, allowing continuous operation when using multiple batteries in rotation.
Agras T70 vs. T100: What’s the Difference?
| Feature | DJI Agras T70 | DJI Agras T100 |
|---|---|---|
| Tank Capacity | 70L | 100L (liquid) / 150L (solid) |
| Max Speed | 60 km/h | 72 km/h |
| Battery | 41,000 mAh | 41,000 mAh (same type) |
| Coverage per Flight | 4–5 ha | 5–6 ha |
| Weight (Takeoff) | 110 kg | 149 kg |
| Terrain Mode | Improved | Advanced LiDAR 3D Terrain Follow |
| Use Case | Mid-size farms | Large-scale operations, citrus, rice |
Verdict: The T70 is lighter and ideal for mixed farms, while the T100 dominates in large-scale spraying with higher payload capacity and stronger propulsion.
