Bose S1 Pro+ Accessory Battery Pack

Power-up and play your Bose S1 Pro+ system for up to 11 hours using the rechargeable S1 Pro+ battery pack. This lithium-ion battery installs easily into the dedicated compartment on your S1 Pro+ for secure and reliable use. The Bose Accessory Battery for the S1 Pro+ PA System features lithium-ion battery technology that provides high-energy density and full-output use of your S1 Pro+ system without compromising volume level. You can also permanently install the battery inside the S1 Pro+ system for safe and easy charging.*As with any battery-operated device, battery performance can vary based on a number of different factors. These include the type of content being played, the volume at which it’s played, and the surrounding temperature. The Bose S1 Pro+ wireless PA system was rigorously tested and verified to provide up to 11 hours of battery life while playing music at room temperature from Spotify’s Global Top 50 at a comfortable volume that you can talk over while listening indoors. A singer/songwriter performing indoors for up to 100 people can expect to get 5 hours or more of battery life at performance-volume levels.
