B-Mount Li-Ion High Load Battery

The Bebob B290CINE is a professional high-load B-Mount lithium-ion battery engineered for demanding cinema production environments. Featuring dual-voltage output support for both 14.4V and 28.8V systems, the battery automatically delivers the correct operating voltage based on the connected B-Mount device or plate configuration.

Designed for compatibility with both 12V and 24V cameras, lighting systems, and production accessories, the B290CINE provides safe and stable power distribution without the risk of over voltage or under powering connected equipment.

Dual-Voltage High Load Performance

The battery supports dual-voltage operation with 14.4V/4s and 28.8V/8s output configurations. Its intelligent B-Mount interface automatically regulates voltage delivery according to the device requirements, ensuring reliable operation across professional cinema workflows.

Equipped with high-quality lithium-ion trimix cells, the B290CINE delivers a maximum continuous discharge current of 20A and supports up to 450W continuous power draw for high-performance production equipment.

Durable Modular Construction

Bebob engineered the B290CINE with a robust modular housing capable of withstanding falls from heights up to 4.9 feet. The modular construction simplifies maintenance by allowing individual mechanical components to be replaced when damaged instead of replacing the complete battery unit.

This repair-friendly design enhances long-term usability while reducing downtime during professional production use.

Flexible Power Connectivity

The integrated Twist D-Tap connector provides flexible cable routing by allowing D-Tap accessories to connect from either side without reversing output polarity. Its rainproof socket design improves cable management for camera rigs and on-location production setups.

A built-in 5V USB output additionally supports charging mobile devices and production accessories directly from the battery during field operation.

Battery Monitoring and Charging

The B290CINE includes a 5-step LED status indicator for monitoring remaining battery capacity during operation. This visual power display allows operators to track battery levels efficiently and plan recharging intervals during extended shoots.

When paired with Bebob BS2 or BS4 chargers, the battery reaches a full charge in approximately six hours, supporting reliable production turnaround schedules.
