Developed specifically for the battery sanders ETSC, DTSC, RTSC: The lightweight, handy Ergo battery provides full freedom of movement and comfortable sanding. It can work as long as with a cord because the battery and EC-TEC motor collaborate perfectly, resulting in a runtime longer than the charging time. Since it is equipped with Bluetooth®, it automatically starts a connected vacuum cleaner simultaneously with the tool – and in combination with the Festool Work app, it delivers detailed information about charging status and operating data, such as temperature or charging cycles. And of course, it is also fully secured with Festool Service.
