Our Pulse Battery is a popular and simple design that incorporates our temperature control algorithm designed to prevent overheating and burning of sensitive oils by sending intermittent pulses of power to the heating coil rather than a direct pulse that creates an uneven vaping experience. Compatibility – The Pulse Battery BY AVEO® Power Supply uses a “510” connection (screw-on connection with M7 thread.) The Pulse Battery is compatible with most cartridges designed for use with breath actuated power supplies. For best results, pair with AVEO® hardware. For use with other hardware, compatibility may vary. The electrical contacts, airflow, and other features may vary from manufacturer to manufacturer. Caution: Fast charger output voltage higher than 5V may damage the battery.
