Description

The Festool SYS 18V TBX Cordless Kit provides four 4.0Ah tabless battery packs and a TCL 6 DUO rapid charger, all housed in a Systainer³ for organised site storage. Designed as an ideal complement to Festool Basic variants, this energy set ensures you always have power available whether you're on a construction site, in a bodyshop, or working on vehicles. The TCL 6 DUO rapid charger simultaneously charges two battery packs at once — meaning a single 240V socket is all you need, saving time and eliminating the hassle of trailing leads or sourcing additional sockets. The BP 18 TBX 4 C-ASI battery packs use tabless cell technology, which reduces heat generation to extend battery service life while delivering consistent, full power output. Bluetooth® connectivity adds a layer of smart functionality, automatically starting a paired Festool vacuum cleaner when a tool is switched on, and enabling detailed charge status monitoring through the Festool app — including temperature readings and charge cycle data. Features and Benefits: • Tabless cell technology delivers full power with low weight for fatigue-free working • Low heat generation extends battery service life • TCL 6 DUO rapid charger charges two packs simultaneously from a single socket • Compatible with all Festool battery packs from 10.8V to 18V voltage classes • Bluetooth® connectivity auto-starts a paired vacuum cleaner when the tool is switched on • Festool app enables monitoring of charge status, temperature, and charge cycles • All components fully covered by Festool Service • Stored and transported in a Systainer³ M 187 for clean, secure organisation Specifications: Capacity: 4.0Ah Voltage (rated voltage): 18V Charging current: 2 x 6.0A Input voltage: 220–240V Product weight without accessories: 5.40kg Contents: 4 x tabless battery pack BP 18 TBX 4 C-ASI TCL 6 DUO rapid charger Systainer SYS3 M 187
