The Canon BP-A30N Battery Pack is a rechargeable lithium-ion battery compatible with Canon's Intelligent Battery system and the EOS C400 cinema camera. The battery features a removable contact cover that can help keep the contacts clean and helps prevent short-circuit discharges when the battery is not mounted on the camera.

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.
