The most powerful and durable battery pack in the Festool range: Whatever the machine or application – the Li-HighPower battery pack provides maximum power and endurance (with a 60 % longer runtime than a 5.0 Ah standard battery pack), even for heavy-duty applications. Like all Festool battery packs, it is perfectly tailored to the brushless Festool EC-TEC motors, offering an extremely high degree of efficiency and maximum output per battery charge. In addition, the powerhouse performs impressively during the charging procedure: Thanks to AIRSTREAM technology, the battery pack is actively cooled before and during the charging procedure, meaning that it is ready for use again extremely quickly with maximum charging power. When paired with a dust extractor equipped with Bluetooth®, the extractor starts automatically when the cordless tool is switched on.
