Swit PB-H290S 290Wh 28V/14V Smart Battery, V-Mount

Professional Bi-Voltage Power for Cinema Rigs

The Swit PB-H290S is a high-performance 290Wh V-mount battery designed specifically for high-voltage cinema cameras like the ARRI ALEXA LF and ALEXA 65. Featuring intelligent bi-voltage technology, it automatically switches between 14.4V and 28.8V output to match your equipment's requirements, ensuring seamless compatibility across your entire kit.

High Capacity and 250W Constant Load

Built with 24 high-class 18650 battery cells, the PB-H290S delivers a massive 290Wh capacity. It supports a constant power output of 250W, making it capable of driving power-hungry setups including the ALEXA LF (160W) alongside multiple on-camera monitors and wireless transmitters simultaneously. This high-load capability ensures a longer overall lifespan compared to standard batteries when used under heavy stress.

Rapid 6A Charging and D-Tap Connectivity

Minimize downtime with 6A super fast charging support. When used with the SWIT S-3812S or PC-P460S chargers, the PB-H290S reaches 80% charge in approximately 2.5 hours and a full charge in under 4 hours. The integrated D-tap socket provides versatile accessory power: 11-16.8V (120W/10A) in normal mode, or a constant 16V (50W/3A) when in 28.8V mode.

Advanced Monitoring and Rugged Durability

The innovative 8-LED digital indicator provides real-time feedback. During discharge, the LEDs display remaining working hours and minutes based on current power consumption. For field reliability, the battery features a dual-housing structure with an inner cell cage and outer anti-shock housing with rubber covers. It is tested to survive drops from 1.5 meters at any angle and carries an IP54 rating for water and dust resistance.
