Sennheiser BA 20 Rechargeable Battery Pack for AVX EKP Compact Receiver

Dedicated rechargeable battery for the Sennheiser AVX EKP plug-on wireless receiver

The Sennheiser BA 20 is a dedicated rechargeable battery pack designed for the Sennheiser AVX EKP compact plug-on wireless receiver. The EKP receiver plugs directly into an XLR input on a camera, mixer, or portable recorder, and the BA 20 provides the internal power to operate the receiver independently of the host device's phantom power, ensuring reliable operation across different equipment types and configurations.

As a spare or replacement battery, the BA 20 ensures uninterrupted operation during long shooting days, multi-event schedules, and rental deployments where the receiver is in continuous use. Having a charged spare BA 20 on hand means the receiver can be powered up again in seconds with a fresh battery swap rather than waiting for a recharge cycle.
