Eartec EVADE Headset Lithium Polymer Battery

Every EVADE headset ships with a Lithium Polymer rechargeable battery, and this is that battery sold on its own. Because it is field replaceable rather than sealed in, a crew can swap a flat pack for a charged one at a break instead of taking the headset out of service.

That is what lets an EVADE system run a full event day or a multi-day install. Keep one spare per headset and one charger port per spare, and the system never stops.
