Audio-Technica LI-320 Lithium-Ion Battery

The LI-320 is the rechargeable lithium-ion battery for Audio-Technica's ATW-DT3202 handheld transmitter in the D50 digital wireless system. A spare pack lets a house band or presenter change mics between sets without pulling a transmitter off stage to sit on a charger mid-show.

It charges in the handheld itself or in an ATW-CHG6/ATW-CHG7 charging station, and remaining capacity is reported through the transmitter and D50 management software so a tech can plan a swap before a battery actually runs out.
