Lithium-Ion Battery Solutions for Drones and Robotics
Commercial-grade batteries with integrated Battery Management System (BMS)
Vanguard’s lithium-ion battery solutions are designed for a broad spectrum of commercial and military UAV, UGV, USV, and UUV applications, providing a flexible and efficient power source tailored to your specific needs.
The advanced fully integrated systems come equipped with an internal Battery Management System (BMS) that operates in harmony with a CANbus-controlled charger and dialog network. The modular design of the battery packs allows for easy configuration to meet various capacity and voltage requirements, with the option to stack multiple batteries for enhanced power output.
Vanguard offers both fixed battery packs, ranging from 1.5kWh to 10kWh, and interchangeable batteries that are compatible across multiple applications for effortless swapping.
Robust Durability & Rigorous Testing
Vanguard batteries are encased in a sturdy, pressure washer-rated housing and metal roll-cage, ensuring maximum protection in extreme conditions. Each unit undergoes extensive testing to endure shock, vibration, extreme temperatures, dust, and water immersion.
Prolonged Operational lifespan
Our batteries are designed for up to 2000 cycles at full power, maintaining 80% capacity even after extensive use. The maintenance-free units are fully serviceable, and due to their modular design, individual components can be replaced rather than the entire battery.
Assured Safety & Efficiency
Each unit features our proprietary Battery Management System, which continuously monitors voltage and temperature across the entire pack, ensuring safe and efficient operation at all times.
Simplified Integration & diagnostics
the adaptable battery units are equipped with two CANbus networks (including one SAE J1939 standard and one flexible) for straightforward integration with existing OEM systems, and troubleshooting can be conducted using standard CANbus diagnostic protocols.
A prequalified plug-and-play charging system can be installed either on- or off-board.

V-Twin EFI Engines for Drones & UAVs
Horizontal shaft electronic fuel injection petrol engines
Vanguard’s V-Twin horizontal shaft petrol engines offer outputs ranging from 17.2 to 29.9 gross kW (23 to 40 gross HP), making them suitable for various UAV and drone applications.
Our advanced electronic fuel injection (EFI) technology fine-tunes the engine’s performance by continuously monitoring various onboard sensors, making real-time adjustments to fuel and spark delivery. This results in improved starting capabilities across all temperatures, smooth operation at any altitude, rapid response to load changes, and significantly enhanced fuel efficiency.
Our latest 29.9 gross kW (40.0 gross HP) engine incorporates cutting-edge electronic throttle control (ETC) technology, enabling the engine to swiftly detect RPM changes and respond instantly to environmental load variations.
By maintaining consistent power output, the engine ensures stable speed, leading to enhanced efficiency.
Key features of Vanguard’s four-stroke EFI engines for UAVs and drones include:
V-Twin OHV Design
Our durable OHV (overhead valve) engine design enhances balance and power output, optimizing performance for longevity and superior fuel efficiency.
Closed-loop EFI System
V-Twin engines utilize an automotive-grade, closed-loop EFI system that can improve fuel economy by up to 25% compared to traditional carburetor engines. The battery-powered ignition with variable timing ensures smoother starts and extends starter life.
High-Efficiency Balanced Architecture
The engine’s dynamically balanced crankshaft, lightweight piston, and ring assembly reduce noise and vibration, while enhancing durability at high temperatures. Angled ports optimize airflow and mixture preparation, resulting in improved efficiency, smoother idling, reduced emissions, and increased power.
Extended Engine Longevity
The design maximizes lubrication and protects critical components. A spin-on oil filter and a cyclonic air cleaner provide advanced protection against airborne contaminants, contributing to a longer engine lifespan.
