The Sennheiser BA60 is a rechargeable battery pack designed specifically to power Sennheiser wireless bodypack transmitters, such as those in the Evolution Wireless G3 and G4 series (SK models). This accessory replaces disposable AA batteries, providing a reliable, eco-friendly, and cost-effective power solution for professional users in touring, broadcast, and installed sound. The battery pack is engineered to match the form factor and voltage requirements of the transmitter, ensuring a secure fit and optimal performance. It utilizes lithium-ion technology, which offers a high energy density, resulting in a long operational time—often comparable to or exceeding that of high-quality alkaline batteries—on a single charge, making it suitable for full-day events or lengthy performances.

The BA60 battery pack is part of a larger Sennheiser charging ecosystem. It is designed to be charged in dedicated multi-bay charging stations, such as the Sennheiser L series chargers, which can simultaneously charge multiple packs. These intelligent chargers monitor each battery individually, delivering the correct charge current and automatically switching to a maintenance mode when full, which helps to maximize the overall lifespan of the battery. The pack typically features clear status indicators or communicates its charge level to the transmitter, which can then display the remaining battery life on its own screen or LED indicators.

By adopting the BA60 rechargeable system, audio professionals eliminate the waste and recurring cost of disposable batteries while gaining the logistical advantage of a centralized power management system. This ensures that all transmitters are always ready with fresh, reliable power, reducing downtime and enhancing the overall reliability of the wireless setup. The Sennheiser BA60 Battery Pack is an essential accessory for any serious user of Sennheiser wireless systems who values operational efficiency, sustainability, and consistent performance.
