The Festool 18V 2xTBX8/SCA16 Energy Set (578903) delivers high-capacity power and rapid recharge capability for demanding Festool 18V cordless power tools. Supplied with two 8.0 Ah BP 18 TBX 8 ASI tabless battery packs and the high-output SCA 16 Rapid Charger, this starter set supplies the sustained energy required for high-load applications such as cordless track saws, circular saws, and mobile dust extractors.

Engineering around tabless cell technology significantly reduces internal electrical resistance and heat generation within the battery pack. This lower operating temperature allows the battery to deliver consistent, uncompromised power under heavy cutting loads while extending overall service life. When depleted, the SCA 16 Rapid Charger utilizes AIRSTREAM active cooling to actively chill the battery pack before and during the charge cycle, restoring an 8.0 Ah battery to full charge in as little as 25 minutes to minimize jobsite downtime.

Integrated Bluetooth technology in each battery pack enables automatic wireless communication with paired Festool CLEANTEC dust extractors, automatically starting dust extraction when the cordless tool is turned on. Operators can also connect via Bluetooth to the Festool app to monitor real-time battery operational data, including charge percentage, temperature, and cycle metrics.

Features & Benefits

• High-Capacity 8.0 Ah TBX Battery Packs: Two included 18V battery packs supply long runtime and high current output for power-intensive cordless applications.
• Tabless Cell Technology: Reduces internal resistance and heat buildup to maintain steady rotational speed and torque under heavy tool loads.
• SCA 16 Rapid Charger with AIRSTREAM: Actively cools battery cells during charging with a 16 A charging current to complete full recharges in as little as 25 minutes.
• Automated Dust Extraction: Onboard Bluetooth automatically triggers a paired CLEANTEC dust extractor when the connected cordless tool powers on.
• Festool App Integration: Provides real-time visibility into battery charge levels, cell temperature, and usage metrics from a smartphone.
• Soft-Touch Non-Marring Base: Rubberized battery housing protects finished work surfaces from scratches and prevents slipping when placed on sloped materials.
• Integrated LED Charge Indicator: Displays remaining battery capacity at the push of a button directly on the pack.
• Comprehensive Warranty Protection: Both battery packs and the rapid charger are fully covered by Festool's 3-year wear-and-tear warranty.
