The SWIT PB-H290S Intelligent Bi-voltage V-Lock Battery Pack is the perfect solution for powering high-voltage cameras like the ARRI Alexa LF/65. It offers both 11-16.8V normal voltage and 22-33.6V high voltage output with automatic recognition and switching. Compatible with Alexa LF/65 and other cameras, which eliminates the risk of incorrect usage.

14.4V/28.8V Auto-Switching

The PB-H290S Bi-voltage battery has a default voltage range of 11-16.8V, making it compatible with standard V-mount cameras and chargers. By using the dedicated V-mount plate KA-A20S from ARRI, the battery can automatically switch to a higher voltage range of 22-33.6V, providing power for Alexa LF/65/SXT/AMIRA cameras.
