Product Overview

Manufacturer: Festool

  • The Festool 577105 Energy Set offers additional battery packs for the workshop and construction site. For all applications and 18 volt devices – when the focus is on compact design and ease.


    The perfect addition: Thanks to the Li-HighPower cell technology, the Li-HighPower battery packs are powerful enough for any application and compatible with all Festool cordless products.

    For machines with extremely long-lasting power needs, such as the AGC 18-125 cordless angle grinder and the DSC-AGC 18 cordless freehand cutting system, we recommend the energy sets with BP 18 battery packs with 5.0 Ah or 8.0 Ah.

    Convenient: Weighing less than 600 grams, the included Li-HighPower Compact battery packs are both 20% lighter and 50% more compact than a 5.0 Ah standard battery pack.

    Dust extraction starts automatically: The Bluetooth® battery packs automatically start the connected mobile dust extractor when the tool is switched on.

    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.

    Charges two at the same time: The DUO rapid charger charges two battery packs at exactly the same time. This makes it suitable for all battery packs from the 10.8 V, 14.4 V and 18 V classes, with the exception of BP-XS for CXS/TXS 10.8 V. The separate LED display at both charging slots shows the current charge status of each battery pack at any time.

    Safely stored: Stowed in Systainer³ products with sufficient space for a total of four battery packs and the DUO rapid charger.

    Mobile: Packed in a Systainer³, the Energy-Systainer can be integrated perfectly into the bott vehicle fixture for easy transport from the body shop to the building site.

    Better with a system: The Systainer³ is compatible with and can be attached to all previous Systainer generations, mobile dust extractors and many more system accessories.
