Specially developed for the ETSC, DTSC and RTSC cordless sanders: The light, handy Ergo battery pack ensures complete mobility and maximum comfort when sanding. The perfect combination of battery pack and EC-TEC motor ensures endurance similar to that of a mains-powered tool, consequently achieving longer running times as charging times. Equipped with Bluetooth®, a paired mobile dust extractor starts automatically when the cordless tool is switched on. Additionally, when used in conjunction with the Festool Work app, you can find detailed information about the charge status and operating data, such as the temperature or charge cycles. And, of course, it is fully covered by Festool Service.

Specially for cordless sanders: The Ergo battery pack is developed for the ETSC 125, RTSC 400, DTSC 400 cordless sanders
Work without interruptions: Thanks to the battery packs with a capacity of 3.1 Ah which run for longer than their charge time
Unique – with battery or cable: For all applications which require an even longer operating performance, the 18 V battery pack can be replaced with the plug it-mains adapter (included in the set and available as an accessory). This creates a mains-powered machine with an unlimited running time in combination with the plug it-cable – ideal in conjunction with a Festool mobile dust extractor
Practical: LED display quickly shows the remaining battery capacity
Convenient: Bluetooth® enables the CLEANTEC mobile dust extractor to be started automatically when the cordless tool is switched on (use of a Bluetooth®-compatible mobile dust extractor is required)
With smart extensions: The Festool WorkApp enables clever additional functions in combination with the Bluetooth® function of the battery pack, such as the detailed display of the charging status and further operating data such as temperature or charging cycles. To quickly and easily identify the battery with the lowest charge status, you can flash the LED indicator directly on the battery pack. Software updates are also possible: Install the newest version to work with the latest tool functions at all times
