Versatile use: The 5.0 Ah battery packs are powerful all-rounders for all applications. Thanks to the Li-HighPower cell technology, they deliver up to 50% more power with our latest generation of saws and the HLC 82 battery planer compared to a standard 5.0 Ah battery pack. Extremely durable: This is ensured by the high-current cells. Charge two at the same time: The DUO fast charger charges two battery packs simultaneously. It is suitable for all battery packs in the voltage classes of 10.8 V to 18 V (exception: BP-XS for CXS/TXS and charger MXC). Automatic vacuum activation: The Bluetooth battery packs automatically start a paired vacuum cleaner when the tool is turned on. Smart enhancements: The Festool app, in combination with the Bluetooth function of the battery pack, offers clever additional features, such as detailed display of charge status and other operating data like temperature or charge cycles. Fully secured: Of course, the DUO fast charger and all battery packs are fully covered by the Festool service. The Festool energy set is the ideal complement to the Festool Basic variants or provides additional battery packs for the workshop and job site.
