Sennheiser BA 10 Rechargeable Battery Pack for D1, AVX, and SL Handheld Transmitters

Dedicated rechargeable lithium battery pack for Sennheiser handheld wireless transmitters

The Sennheiser BA 10 is a dedicated rechargeable battery pack designed for Sennheiser D1, AVX, and SL series handheld wireless transmitters. This lithium battery pack provides reliable, consistent power output with accurate battery level monitoring on the transmitter display, and it recharges in the L 60 or compatible charger without removing the battery from the transmitter housing.

Rechargeable battery packs are the preferred power source for professional wireless deployments because they deliver predictable runtime, accurate remaining-capacity readouts, and lower per-use cost compared to disposable batteries. For touring, rental, and high-frequency-use installations, the BA 10 eliminates the ongoing expense and waste of single-use AA cells while providing the convenience of drop-in charging between events.
