Westcott Lithium Polymer FJ80 II Battery for Fj80 II Speedlights

I finally don't have to swap batteries mid-shoot—this thing powers through 500+ flashes easily, which is a game-changer for event work. The compact size also leaves more room in my bag for other gear.

Battery swaps used to be the bane of my shoots, but this one’s so light I hardly notice it in the bag—and it’s still got an 11.1V punch. The 500+ flash estimate held up for me over a long portrait session, so I’m grabbing a spare before the next wedding.

Shot over 400 full-power pops at an outdoor portrait session and the battery indicator still showed two bars left. The compact size makes it easy to swap in my bag without adding bulk.
