Festool energy-kit SYS 18V 4xTBX 4/TCL 6 DUO

Your 18 V cordless tool power supply.
The Energy-Systainer is the ideal addition to your Festool cordless tools, providing you with the necessary power.

Tabless battery TBX 4: compact: powerful, but light. With tabless cell technology.
The powerful tabless technology battery TBX 4 is your ideal partner for heavy work - lightweight and easy to handle.
Thanks to tabless battery cells: less heating, longer operating time and shorter charging time.
With AIRSTREAM technology, the AIRSTREAM quick charger SCA 16 actively cools the battery pack both before and during charging, making it ready for use again very quickly.
The optimized energy flow of tabless batteries adds performance and extends the battery pack
life.
The Bluetooth® battery pack automatically starts the connected vacuum cleaner when the cordless tool is switched on, and the Festool app provides detailed
information on the charge level, temperature and charging cycles. Of course, it is fully covered by the Festool Service 3-year warranty.

Practical: The LED indicator shows the current battery charge level at any time
For trouble-free work: it goes without saying that the batteries are also fully protected by Festool Service services
Convenient: Bluetooth® enables automatic activation of the CLEANTEC vacuum cleaner when the cordless tool is switched on (the vacuum cleaner must be equipped with Bluetooth® for this)
Safe: surrounding frame made of soft softgrip material to provide protection and stable support for the device on sloping surfaces
Smart extension: The Festool app allows you to use smart additional functions with a Bluetooth®-enabled battery pack, such as viewing the charge level and other work data (e.g. temperature, charging cycles)
Non-tiring work: 4.0 Ah full power at only 600 g weight
Full power: tabless cell technology ensures maximum power even during heavy work
Shorter charging cycles: batteries can be charged immediately after use because they heat up little
Long life: less heating of tabless battery cells extends the life of the batteries
Be it hot or cold: tabless batteries are reliably ready for use even at extreme temperatures
Quickly charged: thanks to the AIRSTREAM quick charger SCA 16, the device is ready for use again in 25 minutes. This is made possible by active cooling during charging
