Eiki EWBTY1 Rechargeable Battery Pack

The EWBTY1 is the detachable lithium battery pack that powers Eiki's EWDC and EWDD wireless discussion units, a 4900mAh cell rated for 24 hours of continuous use on a 4-hour charge. Its pop-up pin contacts and buckled housing snap into the discussion unit and into the EWCH1 charger the same way, so packs move between a rack of spares and the meeting-room units without a fiddly connector.

Keeping a few spares charged is the practical way to run a wireless conference system through a full day of meetings: swap a depleted pack for a charged one between sessions rather than waiting on a mic to charge.
