As someone who shoots weddings with my Sony a7 IV, running out of battery mid-ceremony is my nightmare. These BM Premium batteries have been lifesavers—literally. They slot right into my camera without any annoying 'non-OEM' warnings (unlike some knockoffs), and the dual charger means I always have a fresh one ready during reception downtime.

The 2280mAh capacity isn't quite Sony-original level, but here's the real talk: pairing two of these gets me through a full 10-hour day. I keep one in my gimbal setup and another as backup—no more frantic battery swaps during first dances. The charger's LED indicators are stupidly simple (green = good), and it fits in my pelican case's mesh pocket.

Traveling to destination weddings? This kit shines. The charger handles anything from sketchy Airbnb outlets to rental car adapters without fuss. Pro tip: The batteries do take about 20% longer to charge than OEM, but I just pop them in overnight. For the price of one Sony battery, you get two plus this versatile charger—that's math even us creatives can appreciate.
