The Festool Energy Set provides a convenient way to expand a Festool cordless system or equip Festool Basic tools with batteries and charging capability. Built around Festool’s TBX tabless battery technology, the set combines increased power output, rapid charging and integrated Bluetooth functionality for demanding shop and job-site use.

The set includes four BP 18 TBX 4.0 Ah tabless batteries, providing ample run time to keep multiple tools working throughout the day. The TCL 6 DUO rapid charger charges two batteries simultaneously, reducing downtime and eliminating the need for multiple chargers or additional outlets. Everything is neatly organized and protected in a SYS3 M 187 Systainer case, making the set easy to transport, store and integrate into the Festool Systainer system.

Fully backed by Festool Service.
