SWIT 290Wh Bi-voltage B-mount Battery Pack (BIVO-290)

The BIVO-290 is a 290Wh bi-voltage B-mount battery engineered for high-end cine cameras such as the ARRI ALEXA 35, ALEXA 265, and Blackmagic URSA Cine. Supporting both 14.4V (10.8–16.8V) and 28.8V (21.6–33.6V) outputs, the battery intelligently detects the ID pin resistor of the B-mount plate and automatically switches voltage—ensuring seamless compatibility and eliminating misuse risks.

With a powerful 250W constant load capacity, the BIVO-290 can run an ALEXA 35 for over 3 hours, making it ideal for long-form productions. It features two D-tap outputs: in 14.4V mode, they deliver 11–16.8V; in 28.8V mode, they provide a regulated 16V—perfect for powering monitors, wireless systems, and other accessories. An integrated OLED display shows real-time battery status, including voltage, remaining runtime, power percentage, and warning codes for any detected abnormalities.

The battery supports 100W super-fast charging via the SWIT PC-P461B charger, reaching full charge in approximately 3 hours and 50 minutes for four batteries simultaneously. A built-in LED torch on the rear activates with a double press of the power check button, aiding visibility in dark environments. Designed for durability, the BIVO-290 is drop-proof from 1.2 meters at any angle, making it a rugged and reliable choice for demanding field production.
