Bluesound Pulse Flex Battery Pack

The Bluesound BP100 Battery Pack is an accessory designed to convert the compatible speaker (such as the Pulse Flex) into a truly portable, cordless audio solution. By mounting onto the back of the speaker and supplying power via eight rechargeable AA cells, it enables listening nearly anywhere—park, patio, or living room—while maintaining integration with the existing audio system.

Power Architecture & Rechargeable Design

Inside the BP100 you’ll find a pack of eight rechargeable NiMH AA batteries that power the speaker when detached from mains. Because it uses a familiar battery format, replacement is straightforward when needed. The BP100 is engineered to seamlessly charge when the speaker is connected to AC power, so you’re ready for portable playback when desired.

Battery Life and Usage Flexibility

On a full charge, the BP100 delivers up to six hours of playback time, though actual runtime will depend on volume levels, signal type (Bluetooth, WiFi, optical), and other usage conditions. Users gain the flexibility of wire-free listening without sacrificing the sound quality of the speaker’s built-in amplification or streaming support.

Integration with Speaker & App-Based Monitoring

The battery pack attaches directly to the compatible speaker’s chassis, matching its color options (typically black or white) to maintain visual continuity. Additionally, charge status is visible within the speaker’s app (e.g., BluOS app), allowing you to monitor remaining runtime from your smartphone—a convenience when transitioning from fixed to portable use.
