UAV & UNMANNED SYSTEMS BATTERIES
Custom UAV and Unmanned Systems Battery Solutions
As a custom drone battery manufacturer, Stellova develops battery systems around aircraft voltage, flight-load profile, peak propulsion demand, payload, mission duration, connector requirements and charging workflow.
UAV MISSION REQUIREMENTS
Flight Time and Peak Power Must Be Evaluated Together
Takeoff, climb, hover, cruise, payload operation and landing impose different current demand. Battery selection must balance usable energy, voltage sag, weight, thermal behavior and reserve for a safe landing.
BATTERY DEFINITION INPUTS
Define the Aircraft, Propulsion and Mission Profile
Representative propulsion data and a mission profile are sufficient for the first engineering review.
Mission profile
Define takeoff, climb, hover, cruise, payload operation, landing and required reserve.
Current and thermal limits
State continuous and peak current with duration, repetition, connector and acceptable temperature.
Mechanical and interface
Confirm dimensions, weight target, mounting, cable exit, connector, balancing and telemetry requirements.
HIGH-RATE UAV ENGINEERING
Energy, Discharge Rate and Thermal Limits Are Interdependent
Cell selection, conductor sizing, connectors, pack structure, thermal limits and protection must match the stated current duration and operating environment.
Voltage sag
Evaluate loaded voltage across takeoff and peak events rather than relying only on nominal capacity.
Discharge-rate conditions
State current, duration, repetition, cooling, conductor and connector limits whenever a C-rate is used.
Weight and structure
Balance energy with enclosure, compression, vibration resistance, wiring and installation constraints.
Mission safety
Define reserve energy, low-voltage behavior, temperature limits, fault monitoring and safe-landing strategy.

UAV BATTERY FAQ
Questions to Resolve Before Prototype Release
The final answers depend on aircraft mass, propulsion, payload, mission, environment and required safety reserve.
Are these customer cases?
No. ST-01 through ST-06 and the additional series are product specifications, not claims of completed customer projects.
Why are some current fields “/”?
A reliable value requires current duration, repetition, connector, conductor and thermal test conditions; unsupported figures are not published.
How is flight time estimated?
Use a representative mission profile and loaded power data, then include reserve for landing and battery aging.
Can connectors and voltage be customized?
Yes. The electrical interface, wiring, connector, dimensions and protection are defined for the target aircraft.
