Product Highlights

Reliable runtime for 18V tools.
Charge two batteries at once for less downtime.
Fully backed by Festool Service.
More runtime and fewer interruptions where it counts. Designed for expanding Festool Basic tools or adding capacity for demanding shop and jobsite work, this Energy Set delivers dependable, high-output power throughout the workday. Four 5.0 Ah Li-HighPower battery packs are neatly stored in a Systainer³, providing the runtime professionals rely on to keep tools moving.
5.0 Ah Li-HighPower batteries are powerful all-around performers designed for a wide range of applications. Paired with the TCL 6 DUO rapid charger, two batteries can be charged simultaneously—keeping tools running longer and reducing downtime between tasks.
Like all Festool batteries and chargers, every component in this Energy Set is fully covered by Festool Service. That means dependable support, long-term reliability, and peace of mind—so you can stay focused on the work, not the power supply.

Features and Benefits

Versatile, high-output power. The 5.0 Ah Li-HighPower battery packs are true all-around performers, delivering strong, sustained output across a wide range of applications. Advanced Li-HighPower cell technology provides up to 50% more power with Festool’s latest generation of saws and the HLC 82 cordless planer compared to a standard 5.0 Ah battery.
Built for long service life. High-current-resistant cells are engineered to withstand demanding, everyday use—helping extend battery lifespan and maintain reliable performance over time.
Charge two batteries at once. The TCL 6 DUO rapid charger charges two battery packs simultaneously, keeping tools running with minimal downtime. Compatible with most Festool lithium-ion batteries from 10.8 V to 18 V (except BP-XS for CXS/TXS and MXC chargers).
Automatic dust extraction start. Bluetooth®-enabled battery packs automatically start a paired Festool CLEANTEC dust extractor when the cordless tool is switched on—streamlining workflow and improving jobsite cleanliness.
Smart battery insights. When used with the Festool app, Bluetooth® connectivity provides access to detailed operating data such as charge level, temperature, and charge cycles—helping you monitor performance and plan work more efficiently.
