Purpose-Built Power for Sigma BF Cameras

The Sigma BP-81 is a dedicated lithium-ion battery pack engineered exclusively for Sigma BF camera bodies. It supplies the electrical energy required to operate the camera during stills capture and video recording. This accessory is aimed at photographers and videographers who need a reliable replacement or spare cell for their Sigma BF system.

3300 mAh Capacity Determines Runtime

The single specification that governs whether this pack meets a shooter's needs is its 3300 mAh rating at 3.6 V. This capacity dictates how many frames or minutes of footage can be recorded before a recharge is required. Users with lighter workloads may find a single pack sufficient, while those covering long events or travelling without mains access will likely need multiple units.

Stable Output with No Active Cooling

The cell delivers a steady 3.6 V nominal voltage through solid-state chemistry, so it generates no audible noise and requires no fan or heatsink. In normal shooting conditions the pack warms only slightly, and its internal management circuitry regulates current draw to protect both the battery and the camera. There are no moving parts to wear out or produce vibration.
