Improved Flash Performance. The Sony FA-EBA1 External Battery Pack is compatible with the Sony HVL-F60RM2, HVL-F60RM, and HVL-F60M flashes. With eight AA batteries installed, it reduces recycle times to a mere 0.6 second and increases the number of flashes to approximately 600 per session. If you power it with four AA batteries, it’ll act as the flash’s priority power source to reserve the batteries in the flash itself.

High-Quality Build. The dust- and moisture-resistant build lets you work in less-than-optimal conditions, and it boasts reinforced cable-connection points.
