Sennheiser B 30 Battery Sled (AA) for SK D1, SK AVX, and SL Bodypack Transmitters

AA battery sled adapter for using standard batteries in Sennheiser bodypack transmitters

The Sennheiser B 30 is an AA battery sled designed for the SK D1, SK AVX, and SL series bodypack wireless transmitters. This sled allows users to power their bodypack transmitter with standard AA batteries as an alternative to the dedicated Sennheiser rechargeable battery pack, providing a reliable backup power option when rechargeable batteries are depleted, damaged, or unavailable.

The B 30 is the bodypack counterpart to the B 10 handheld battery sled. Having both sleds in a wireless kit ensures that every transmitter in the system can be powered with standard AA cells when needed, making the system resilient against unexpected power situations during live events, productions, and rental deployments.

Is the B 30 the same as the B 10?

No. The B 30 is designed for bodypack transmitters (SK D1, SK AVX, SL bodypack), while the B 10 is for handheld transmitters (SKM D1, SKM AVX, SL handheld). They are not interchangeable.

How long does a single AA battery last in the B 30?

Battery life depends on the cell type and transmitter model. Alkaline AA cells typically provide several hours of operation. Lithium AA cells offer longer life and better performance in cold conditions.
