Sound Devices XL-B14500 Lithium-Ion Rechargeable Battery

Rechargeable Li Ion Battery Solution for Astral TX Transmitters

The Sound Devices XL-B14500 is a rechargeable 3.7V lithium-ion battery designed to power Astral TX transmitters with extended runtime and reliable performance. Sold as a set of two, these batteries provide a dependable power solution for professional audio workflows, helping users maintain continuous operation during long production days without frequent battery changes.

Extended Runtime for Demanding Production Environments

Battery life is critical in film, broadcast, and live audio applications. These batteries are optimized to deliver over 10 hours of runtime when used with lavalier microphone inputs, allowing users to complete extended recording sessions without interruption. This makes them a practical choice for professionals working in fast-paced and time-sensitive environments.

Flexible Power Configuration for Different Workflows

The XL-B14500 batteries can be used individually or in combination, allowing the transmitter to operate with one, two, or three batteries depending on power requirements. This flexibility gives users control over weight, runtime, and redundancy based on the needs of each production setup.

Rechargeable Convenience with Multiple Charging Options

These lithium-ion batteries can be recharged directly within the Astral TX transmitter or using any compatible 3.7V Li-ion battery charger. This dual charging capability provides convenience and ensures batteries are ready for use whether in the studio or on location.

Hot Swappable Design for Continuous Operation

Designed for uninterrupted workflows, the batteries support hot swapping, allowing users to replace individual cells without powering down the transmitter. This feature is especially valuable in live production and broadcast environments where maintaining continuous signal transmission is essential.

Built In Safety Protection for Reliable Use

Each battery includes integrated protection circuitry to guard against excessive current draw and ensure safe operation. This added layer of protection helps extend battery life and provides confidence when using the batteries in professional audio equipment.
