## Description

Keep your Festool cordless tools powered and ready with the Festool 18V SYS Energy Set, an essential addition to Festool Basic variants or as an extra power source for the workshop and job site. Designed to meet individual energy needs, this set includes two 4.0Ah Li-HighPower battery packs—lightweight yet powerful, making them ideal for a wide range of Festool tools. The TCL 6 DUO rapid charger allows simultaneous charging of two batteries, eliminating the need for multiple power sockets and reducing downtime. With room for up to four batteries in the durable Systainer³ case, this kit ensures organized storage and easy transport. Fully backed by Festool Service, it’s a smart, efficient energy solution for professionals. Features and Benefits • The perfect addition: Thanks to the Li-HighPower cell technology, the Li-HighPower battery packs are powerful enough for any application and compatible with all Festool cordless products. (For machines with extremely long-lasting power needs, such as the AGC 18 cordless angle grinder and the DSC-AGC 18 FH cordless freehand cutting system, we recommend the energy sets with BP 18 battery packs with 5.0 Ah or 8.0 Ah.) • Convenient: Weighing less than 600 grams, the included Li-HighPower Compact battery packs are both 20% lighter and 50% more compact than a 5.0 Ah standard battery pack • Dust extraction starts automatically: The Bluetooth® battery packs automatically start the connected mobile dust extractor when the tool is switched on • With smart extensions: The Festool WorkApp enables clever additional functions in combination with the Bluetooth® function of the battery pack, such as the detailed display of the charging status and further operating data such as temperature or charging cycles. To quickly and easily identify the battery with the lowest charge status, you can flash the LED indicator directly on the battery pack. Software updates are also possible: Install the newest version to work with the latest tool functions at all times
