EVERSE 8 is powered by a custom-designed high-capacity Li-ion battery pack, fully optimised for audio use and providing plentiful power for up to 12 hours of run time. Protection circuitry reduces the risk of your battery discharging to such a low voltage that it can no longer be recharged – for example, after long periods in storage. Tool-free screws make removing the battery pack effortless. Uncompromising sound quality, unplugged.
