Festool 18V 3.1Ah ERGO Bluetooth Batteries and Line adapter for Cordless Sanders

Festool Ergo batteries provide 18V of power to Festool cordless sanders - the ETSC125, DTSC and RTSC.

The batteries feature AirStream technology (the AS in the battery's name), which directs cool air through targeted air ducts in the battery so the battery does not overheat. You can charge the batteries in any Festool charger other than the MXS.

If you have a cordless sander, you will also be interested in the Mains Adapter, which physically resembles the Ergo battery, and consists of a cable that can plug into the wall or dust extractors as a power source. It provides uninterrupted power from AC power sources (110V AC) using a Plug-It cable. This gives a power source alternative for continuous sanding performance when you don’t want to use battery power.
