Dedicated to the Sony HVL-F60RM and HVL-F60M flashes, the FA-EBA1 External Battery Pack helps to reduce flash recycle times as well as provide more flashes per session. Using a battery magazine system, up to eight AA alkaline or NiMH batteries can be used to offer up to approximately 660 flashes per set of batteries, along with fast recycle times of 0.6 seconds. This magazine can also be used with just four AA batteries in place, and when in use, this pack will be used as the priority power source in order to alleviate power drain on the batteries in the flash.

The battery pack is dust- and moisture-resistant for use in inclement conditions and the cable connection points have been reinforced for improved reliability. Additionally, the included protective pouch can be used to mount the battery pack to a tripod leg or other stand for hands-free use.
