Sennheiser BA 2015 NiMH Rechargeable Battery Pack for SK G3/G4 and 2000 Series Bodypacks

NiMH rechargeable battery pack for Evolution Wireless G3, G4, and 2000 Series bodypack transmitters

The Sennheiser BA 2015 is a NiMH rechargeable battery pack designed for bodypack transmitters and components in the Sennheiser SK G3/G4 (Evolution Wireless third and fourth generation) and 2000 Series wireless systems. This battery pack replaces standard AA cells with a dedicated rechargeable unit that provides accurate battery level monitoring, predictable runtime, and the ability to recharge in Sennheiser L 2015 and compatible chargers.

For operations running multiple bodypack transmitters across touring, worship, theater, and broadcast environments, the BA 2015 significantly reduces the ongoing cost of disposable batteries while providing more reliable power level reporting than standard AA cells.
