The Canon BP-A30N Battery Pack is a standard-capacity power option for select Canon cameras. This updated "N" series pack features additional power output that will enable select features of newer Canon cinema cameras, such as the Multi-Accessory Shoe of the EOS C400. The battery incorporates a small push button that activates the remaining power indicators on the battery, allowing you to quickly determine its approximate power level without having to attach it to a camera. It also comes with a contact cover to keep it protected when not in use.
