The Festool 578946 SYS 18V 4xTBX4/TCL6 DUO Energy Set is a complete cordless power solution designed to expand your Festool 18V system and keep your tools running with minimal downtime. Featuring four advanced BP 18 TBX 4.0 Ah tabless batteries, a TCL 6 DUO rapid charger, and a protective SYS3 M 187 Systainer, this set is ideal for professionals who need dependable power for busy jobsites, mobile setups, and workshop applications.
Built with Festool’s latest tabless battery technology, the TBX 4.0 Ah batteries deliver strong, consistent output in a compact and lightweight design. Improved energy flow and reduced internal resistance help provide maximum power under load while reducing heat buildup, supporting longer battery service life and sustained performance over time.
The included TCL 6 DUO rapid charger charges two battery packs simultaneously, helping reduce downtime and eliminate the need for multiple chargers or outlets. This makes the Energy Set especially useful for crews running several cordless tools throughout the day.
Bluetooth® battery functionality adds smart system integration, allowing compatible batteries to automatically start a paired Festool CLEANTEC dust extractor when the cordless tool is switched on. When used with the Festool app, users can also access detailed battery information such as charge level, temperature, and charge cycle data.
Everything is neatly stored and protected in the included SYS3 M 187 Systainer, making transport, organization, and integration with the Festool Systainer system simple. Fully backed by Festool Service, this Energy Set delivers efficient power management, faster workflows, and long-term cordless confidence.
