Westcott 鋰離子聚合物電池，適用於 FJ400 AC/DC 閃光燈

Getting a full 480 pops per charge means I can shoot an entire session without swapping batteries, which is exactly what I needed. The pack slides into the strobe securely and feels solidly built.

The 2.5-hour recharge time is a lifesaver between sessions, and getting nearly 500 full-power pops out of one charge means I’m not scrambling for an outlet mid-shoot. It’s compact enough to slip into my bag without adding much weight, which makes location work way easier.

Finally got the pack for my strobe and it's honestly a relief to have this kind of battery life—480 full-power flashes means I can shoot a whole session without stopping. The 2.5-hour charge time is pretty reasonable for that output, too.
