Festool Energy Set 578947 – 18V 8.0Ah Tabless Battery & Charger Kit

The Festool Energy Set 578947 provides a complete high-capacity power solution for demanding jobsites and workshops. The set combines four 18V BP 18 TBX 8.0Ah tabless batteries, two SCA 16 rapid chargers and a Systainer³ SYS3 M 187 for convenient storage and transport.

Designed for high-demand cordless tools such as saws and dust extractors, the BP 18 TBX 8 batteries feature tabless cell technology to reduce internal resistance and heat buildup while delivering consistent power and extended runtime.

The included SCA 16 rapid chargers use AIRSTREAM active cooling technology to help cool batteries before and during charging, allowing batteries to be recharged and returned to work quickly — in as little as 25 minutes.

High-Capacity Power for Demanding Applications

Each BP 18 TBX battery provides 8.0Ah of capacity, giving you extended runtime for power-hungry applications. Tabless cell technology helps reduce electrical resistance and heat generation, supporting consistent performance when the tool is working under heavy load.

Fast Charging with AIRSTREAM Technology

The two included SCA 16 rapid chargers feature AIRSTREAM active cooling, which helps manage battery temperature during charging. With the appropriate setup, compatible batteries can be ready for use again in as little as 25 minutes, helping minimize downtime.

Bluetooth® Connectivity

The Festool battery system also provides convenient Bluetooth® connectivity. When paired with a compatible CLEANTEC Dust Extractor, the dust extractor can automatically start when the connected tool is switched on.

Battery information such as charge level, temperature and usage data can also be monitored through the Festool app.

Organized Storage & Transport

The included Systainer³ SYS3 M 187 provides a practical solution for keeping the batteries and chargers organized and protected. Its portable design makes it easy to transport your complete energy system between the workshop and jobsite.
