USB-C Rechargeable NP-F550 Battery

The SmallRig 4331 is a replacement power cell for Sony NP-F550 devices such as cameras, LED video lights, monitors and sliders. It stores 3500 mAh at a nominal 7.27 V and can deliver up to 10 A of continuous current. The pack weighs 4.69 oz and uses a fire-resistant ABS and PC shell with a frosted finish.

USB-C Input at 5 V 2.3 A

Charging is handled through a built-in USB-C port that accepts a maximum of 5 V at 2.3 A from power banks, wall adapters or car chargers. A full charge takes roughly three hours, so the battery can be topped up between takes without a dedicated cradle. The connector replaces the proprietary contacts found on older NP-F packs.

Sustained 10 A Output for Continuous Loads

Under steady draw the cell maintains its rated 7.27 V while supplying up to 10 A, keeping lights and monitors stable during long recordings. The higher capacity extends run time compared with standard NP-F550 units. Note that the larger physical envelope prevents direct insertion into the BMPCC 6K Pro battery door.

Questions about this item

How long will the 3500mAh capacity actually run my camera or light on set?

The 3500mAh rating means the battery stores enough energy for longer shoots compared with standard NP-F550 cells, though exact runtime depends on the power draw of your specific camera, LED light, monitor or slider.

What does the USB-C 5V 2.3A input mean for recharge time between takes?

The USB-C port accepts up to 5V at 2.3A, so you can fully recharge the battery in about three hours from a power bank, wall adapter or car charger.

Will the larger NP-F550 USB-C body fit inside my BMPCC 6K Pro battery door?

No — this model is physically larger than a standard NP-F550 and cannot be inserted directly into the BMPCC 6K Pro battery compartment.
