Ayaa UAV Power

AYAA TECH develops smart battery management systems for professional UAVs, from inspection and agricultural drones to heavy-lift aircraft. Drawing on battery and BMS experience dating back to 2006, the company supplies standard boards and develops custom solutions for UAV manufacturers and battery-pack integrators. Its engineering support covers battery configuration, protection logic, thermal management and communication with flight-control systems.

As a leading supplier of intelligent battery management systems, Ayaa has established a dedicated R&D center for drone BMS, specializing in providing reliable, customized battery management system (BMS) solutions for drone battery engineers, drone manufacturers, and battery pack integrators. Its products are designed to enhance battery safety, real-time monitoring, communication integration, and power reliability to meet the demanding requirements of drone applications.

Key Features of Dedicated Drone BMS

High-Inrush Battery Connection
Built-in active pre-charge limits inrush current during high-voltage connection, reducing connector arcing and protecting avionics from voltage spikes. Applicable Models: EF-001, EF-002, EF-003, EF-006, EF-011, EF-012

Critical In-Flight Anomalies
Detects over-temperature, over-current, and low-voltage events in flight, sending critical alerts without cutting propulsion power.

Autopilot Telemetry & Integration
Native CAN support for DroneCAN (Cyphal), PX4, and commercial autopilots, streaming cell voltage, current, temperature, and battery health data.

High-Dynamic Range Estimation
Coulomb counting with temperature and impedance compensation maintains SOC estimation error at ≤5%, reducing false drops during high-load voltage sag.

Sub-Zero Cold Weather Operations
Below 0°C, the BMS drives external heating elements to warm cells before takeoff and restore high-rate discharge performance. Applicable Models: EF-003, EF-007, EF-008

Field Diagnostics & Wireless Inspection
BLE connectivity lets ground crews view cell data, adjust protection settings, and run diagnostics from a mobile app without cables. Applicable Models: EF-001, EF-002, EF-003, EF-006, EF-007, EF-012

Post-Flight Event Traceability
Non-volatile memory records cycle data, current spikes, thermal events, and fault codes for post-flight analysis and root-cause tracing.

Prolonged Storage & Inactive Periods
After extended idle periods, the BMS automatically discharges the pack toward ~3.85V/cell to reduce swelling and storage degradation. Applicable Models: EF-001, EF-002, EF-003, EF-004, EF-007, EF-008

Custom Drone BMS Support

Ayaa also provides OEM/ODM Drone BMS development services for UAV projects with special electrical, mechanical, or communication requirements. The company can support customers from technical requirement analysis to BMS design, sample testing, production, and delivery.

Customization can include:

• Voltage range
• Current rating
• Battery series count
• Board size
• Connector layout
• Communication protocol
• Firmware logic
• Protection thresholds
• System integration requirements

This makes Ayaa a suitable partner for UAV battery engineers developing new drone battery platforms, as well as procurement teams looking for a BMS supplier that can support project-specific technical and production requirements.
