Power & Energy Systems
Mission-grade drone battery for sovereign defence platforms
Energy Systems for Contested Environments
Modern autonomous systems are only as reliable as the energy systems that power them. Sentricon designs and assembles mission-specific power and battery systems in-house to ensure operational continuity, regulatory compliance, and long-term sustainment in contested environments. This capability underpins all Sentricon platforms, including WIDOWSWARM, and reflects a deliberate response to the realities of modern conflict, sanctions risk, and increasingly fragile global supply chains.
Battery System Design
Sentricon engineers design mission-specific battery systems tailored to platform endurance, load profiles, and operational constraints. Power architecture is optimised at the system level to balance energy density, weight, thermal behaviour, and safety margins, ensuring reliable performance across sustained autonomous operations rather than consumer duty cycles.
Manufacturing & Assembly
Battery packs are assembled in-house using Tier-1 lithium-ion cells and controlled production processes. This approach ensures consistent quality, traceability, and durability while avoiding reliance on externally assembled consumer battery packs. Each system is built to support long-term sustainment and predictable performance in demanding operational environments.
Testing, Validation & Compliance
All battery systems undergo structured electrical, thermal, and mechanical validation to confirm performance under representative operating conditions. Testing focuses on reliability, fault tolerance, and predictable failure behaviour, ensuring compatibility with defence and partner-nation safety expectations and real-world deployment requirements.
Advanced Drone Battery Solutions
Praesidium’s drone battery systems are engineered specifically to support the electrical stability and endurance demands of autonomous and remotely piloted aircraft. By designing power architectures around sustained load profiles rather than consumer duty cycles, our systems reduce voltage sag and transient brownouts that commonly disrupt avionics, sensors, and communications during high-demand flight phases. The result is improved flight reliability, consistent sensor performance, and greater mission availability across extended ISR operations, degraded weather conditions, and high-power manoeuvres. This approach ensures drones remain predictable, controllable, and operationally effective when power stability matters most.
Why In-House Power Systems Matter
While commercial battery packs are widely available at low cost, reliance on externally assembled energy systems introduces unacceptable risk for mission-critical applications. Praesidium’s approach prioritises supply-chain resilience, predictable and repeatable performance, sovereign control of critical components, and long-term platform supportability. This is not a cost-driven decision; it is an operational risk decision.
Tier-One Cells, Controlled Assembly
Praesidium power systems are built using Tier-1 lithium-ion cells sourced from globally recognised manufacturers supplying the automotive and aerospace sectors. By assembling battery packs in-house, we retain direct control over cell chemistry and lot traceability, electrical configuration and load profiles, thermal behaviour and degradation characteristics, as well as battery management and protection architecture. This approach avoids common issues found in consumer and third-party battery packs, including mixed cell lots, unknown ageing history, and reliance on consumer-grade firmware, ensuring predictable performance and long-term reliability in mission-critical applications.
Mission-Driven Battery System Design
Operational platforms place different demands on power systems depending on endurance requirements, payload loads, environmental conditions, and duty cycles. Praesidium designs and assembles battery systems at the platform level to meet these mission-specific requirements, balancing energy density, power stability, thermal behaviour, and lifecycle considerations.
This capability allows energy systems to be tailored where necessary to support unique operational constraints, integration requirements, or regulatory environments, while maintaining consistent quality, traceability, and long-term supportability across Sentricon platforms.
Engage With Us on Mission-Specific Power Requirements
Designed for Contested Environments
Praesidium power systems are designed to support long-duration ISR and autonomous missions, operate reliably in cold-weather and degraded conditions, deliver sustained discharge profiles rather than short consumer duty cycles, and exhibit predictable, non-catastrophic failure modes appropriate for mission-critical environments.
Supply-Chain Resilience
Praesidium strengthens supply-chain resilience by reducing exposure to embargoes and export restrictions, avoiding dependence on any single foreign assembler, and enabling rapid substitution of suppliers if disruption occurs. This approach ensures continued system availability and sustainment even under conditions of geopolitical uncertainty.
Platform-Level Capability
As a platform-level capability, Praesidium’s Power & Energy Systems enable endurance and reliability across all Praesidium systems, support long-term sustainment and lifecycle management, and ensure deploy ability across allied nations operating under differing regulatory and compliance regimes.
Summary
Praesidium’s Power & Energy Systems capability ensures that our platforms remain deployable under wartime conditions, supportable across long operational lifecycles, and resilient to sanctions, embargoes, and supply-chain disruption. By retaining control of energy architecture and assembly, Praesidium ensures alignment with NATO and partner-nation expectations while preserving operational freedom in contested environments. Sovereign systems require sovereign control of energy.
