Festool SYS 18V 2x4,0/TCL 6 DUO Charger and Batteries 2x4Ah 18V (577109)

Well stowed away and charged in a flash: Two 4.0 Ah Li-HighPower Compact battery packs. One DUO rapid charger. In the Systainer.
The Festool Energy set is the ideal addition to the Festool Basic variants and also offers additional battery packs for the workshop and construction site. Available with different equipment according to the individual main applications and energy requirements. Always with sufficient space for a total of four battery packs – of which two can be charged at the same time using the TCL 6 DUO rapid charger. Particularly practical: You no longer need to look for another socket for a second charger – making work easy and saving time on construction sites, in bodyshops and in vehicles. Of course everything cleanly packaged in the Systainer and fully covered by Festool Service.

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 cordless angle grinder and the DSC-AGC 18 FH 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 voltage classes 10.8 V to 18 V (with the exception of: BP-XS for CXS/TXS and MXC charger). The separate LED display at both charging slots shows the current charge status of each battery pack at any time
Safely stored: Stowed in Systainer products with sufficient space for a total of four battery packs and the DUO rapid charger
Mobile: Packed in a Systainer, the Energy-Systainer can be integrated perfectly into the bott vehicle fixture for easy transport from the body shop to the building site
Systems get it done: The Systainer is compatible with and can be attached to all previous Systainer generations, mobile dust extractors and many more system accessories
