## 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.
