Okay, so I’ve been using this SmallRig dummy battery for my Sony A7S III, and holy smokes—it’s a game-changer! No more frantic battery swaps during long shoots. Just plug it in, and boom—continuous power. The 10-foot cable is *chef’s kiss* perfect for my rig.

But here’s the tea: after ~4 hours, it does the whole 'low battery' drama. Unplugging and restarting fixes it (kinda like turning it off and on again). Annoying? Maybe. Dealbreaker? Nah.

Also, ZERO compatibility warnings (unlike some knockoffs). Fits snug as a bug in my FX3 with a cage. Overheat protection? Check. Feels premium? Double-check. SmallRig nailed it—this is the dummy battery Sony should’ve made.

PSA: If yours throws a warning, email support—they’ll hook you up with an updated unit (their customer service slaps).
