Bluesound BP100 Battery Pack

The BP100 easily attaches to the back of your Pulse Flex 2i speaker (available separately). With the BP100 battery pack, your Bluesound Pulse Flex 2i becomes a truly portable high-performance speaker. It easily mounts on the back of the speaker, freeing it from its AC power cable. Take your music out on the porch, or even out to the park. (Just remember, the Flex 2i isn't waterproof.) Stream your music via high-resolution Bluetooth® aptX® anywhere, or via Wi-Fi within range of your home network. You can even make a wired connection through the speaker's combination mini-optical/stereo minijack audio input.
