The most powerful and durable battery pack in the Festool range: No matter what machine or application – the Li-HighPower battery pack delivers maximum power and endurance with a 60% longer runtime than a 5.0 Ah Li-HighPower battery pack, even for heavy-duty tasks. Like all Festool battery packs, it's perfectly tuned to the brushless Festool EC-TEC motors – this results in an impressive efficiency rate and top output per battery charge. Plus, it's pretty impressive when it comes to charging: thanks to AIRSTREAM technology, the battery pack gets actively cooled with the AIRSTREAM Rapid charger SCA 16 before and during charging, so it’s back up and running in no time. With Bluetooth®, it automatically starts a paired mobile dust extractor as soon as you switch on the cordless tool. And when used with the Festool app, it gives you detailed info on charge status and operating data like temperature and charging cycles. And, of course, it’s totally covered by Festool Service.
