The Festool Energy Set SYS 18V 4xTBX8/2xSCA16 (578947) provides a complete high-capacity power solution for demanding 18V cordless tools on the jobsite and in the workshop. Supplied with four 8.0 Ah BP 18 TBX 8 ASI tabless battery packs, two high-output SCA 16 Rapid Chargers, and a Systainer SYS3 M 187 storage case, this set delivers maximum runtime, rapid turnover, and organized mobility for heavy-duty cordless operations such as continuous track saw cutting, timber framing, and portable dust extraction.

The tabless cell architecture in the BP 18 TBX 8 ASI batteries lowers internal electrical resistance and minimizes heat buildup under continuous tool loads. This reduced thermal stress allows tools to maintain steady torque and output during demanding cuts while prolonging battery pack service life. During charging, the SCA 16 Rapid Charger uses AIRSTREAM active cooling to actively draw air through the battery pack before and throughout the charge cycle, restoring an 8.0 Ah pack to ready status in as little as 25 minutes and enabling rapid rotation between four batteries and two charging bays.

Integrated Bluetooth technology in each battery pack enables wireless integration across the Festool system. When paired with a CLEANTEC dust extractor, powering on a cordless tool automatically triggers the extractor to maintain dust-free working conditions without manual switches. Operators can also connect the batteries to the Festool app to monitor charge levels, internal temperature, and usage statistics directly from a mobile device. The entire set stores neatly in the included Systainer³ case, latching seamlessly into Festool Systainer stacks and mobile workstations for streamlined transport.

This SYS 18V 4xTBX8/2xSCA16 Energy Set (578947) is compatible with Festool 18V cordless tools requiring maximum power and extended endurance. Note: It is not compatible with Festool ETSC 125, RTSC 400, or DTSC 400 compact sanders, or the CTC SYS cordless dust extractor.
