Direct replacement for Fiio E18

This Cameron & Co battery fits the Fiio E18 portable USB DAC amplifier. It matches the original PL805053 1S1P part and uses a lithium-polymer cell rated at 3.7 volts and 3000 milliampere-hours. The pack is supplied new in black.

Sustained capacity for long listening

The 11.10 watt-hour rating supports extended playback sessions without a sudden voltage drop. Lithium-polymer chemistry maintains a stable output as the charge declines, so the amplifier keeps its headroom during continuous use rather than fading after a short burst.

3000 mAh capacity decides fit

At 3000 mAh the cell stores enough energy for multi-hour portable use while staying within the 53.85 by 50.00 by 11.12 millimetre footprint the E18 chassis allows. Buyers who need more storage than 3000 mAh cannot use this pack.
