Sennheiser BA 20 Li-Ion Battery for AVX Series

The BA 20 is the rechargeable pack built for Sennheiser's AVX on-camera wireless line, a small 0.43 Ah cell that keeps the AVX bodypack and handheld transmitters light on a camera rig. It slots into the EKP-AVX receiver's charging cradle as well as the transmitters themselves.

One pack size covers the whole AVX family, so a shooter can carry spares that work across the AVX-Combo-SET, AVX-835-SET, AVX-ME2-SET, and AVX-MKE2-SET without tracking multiple battery types.
