External Batteries & Controls

External batteries and controls give you flexible installation options, extended range, and easy integration across different Halo outboards.

5kW External Battery Pack

The Blade external 5 kW battery pack and Helm Pro controls work together as the core of the Halo power system. The 48 V architecture with 150 A max discharge delivers strong, reliable output, while quick-swap connectors make battery changes fast and effortless. The Helm Pro throttles—available in both wired and wireless versions—offer precise, responsive control and a refined feel. Beautiful tinted tempered-glass displays provide real-time system data in a sleek, durable form. Together, they define Blade’s advanced approach to marine batteries and controls. Competitors rely on outdated propulsion that lags off the line — we don’t. Our Halo Core Technology delivers instant torque, higher sustained efficiency, and relentless acceleration that leaves slow outboards behind.
