Power your entire 18V system.

Whether you’re expanding a Festool Basic tool or adding capacity to an existing setup, the Energy Set delivers a complete, ready-to-work power solution. The set includes four TBX 4.0 Ah tabless battery packs and the TCL 6 DUO rapid charger, all neatly organized in a Systainer³—providing ample power for both the shop and the jobsite.

Full power, low weight.

The TBX 4 Compact batteries deliver impressive power in a lightweight, well-balanced design. Advanced tabless cell technology improves energy flow, reduces heat buildup, and enables longer runtimes and faster charging. With the DUO charger, two batteries can be charged simultaneously—keeping tools running with minimal downtime.

Backed by Festool Service.

Like all Festool batteries and chargers, the components in this Energy Set are 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.

More power with less fatigue

The TBX 4 Compact Battery delivers full power in a lightweight, well-balanced design. At just 1.3 lbs (600 g), it reduces user fatigue during extended work while maintaining strong, consistent performance for demanding cordless applications.

Built for system integration

The Systainer³ is designed to integrate seamlessly with Festool storage and vehicle racking systems, allowing batteries and chargers to be transported securely and efficiently from the shop to the jobsite as part of a complete system.

Smart features built in

Bluetooth® connectivity automatically starts a paired Festool CLEANTEC dust extractor when the cordless tool is switched on. When used with the Festool app, users can access detailed battery data such as charge level, temperature, and charge cycles at any time.
