Festool 578745 Tabless Battery Pack BP 18 TBX 4 C-ASI introduces Festool’s latest tabless cell technology, delivering higher power output, cooler operation, and longer service life without added weight. By eliminating traditional cell tabs, energy flows more efficiently through the battery, reducing heat buildup while improving power delivery, runtime, and charging speed. This results in stronger, more consistent performance for demanding applications, with less stress on the battery over time. Paired with Festool’s AIRSTREAM charging system, the TBX 4 battery is actively cooled before and during charging when used with the AIRSTREAM SCA 16 quick charger. This active cooling allows the battery to recharge faster and return to work sooner, making it ideal for professionals who rely on continuous productivity. The optimized energy flow of tabless technology not only boosts tool performance but also helps extend overall battery lifespan. Integrated Bluetooth® connectivity adds smart functionality, automatically starting a paired Festool dust extractor when the cordless tool is switched on. When used with the Festool app, users can access detailed battery data including charge level, temperature, and charge cycles. Compact, powerful, and intelligent, the TBX 4 battery delivers advanced performance in a familiar form factor and is fully backed by Festool’s 3-year warranty for complete peace of mind.
