When you're on a roll while photographing, it's extremely frustrating to be held back by a lack of battery power or having to swap out batteries. The high-performance Li-Ion battery has been specifically designed for the A1X and lasts up to four times longer than cumbersome AA batteries without any drop in performance. It can be mounted on the A1X in seconds and removed just as quickly. Another advantage is the fast charging. This ensures you are covered even during longer shoots. Our Li-Ion batteries are UN-certified, allowing them to be taken on airplanes. All necessary documents can be found in the download section.
