The Sound Devices XL-B18650 is a proprietary lithium-ion battery designed specifically for the A20-HH handheld microphone/transmitter. Featuring a 4000mAh capacity, it delivers over 10 hours of runtime, with the transmitter set to 10mW, ensuring your microphone stays powered through extended performances and recording sessions.
For added convenience, the XL-B18650 can be charged directly within the A20-HH via its USB-C connection or removed for external charging using compatible third-party chargers. This flexibility makes it easy to keep your microphone powered and ready, whether on stage or in the studio.
