Festool HighPower BP 18 Li 4.0 HPC-ASI Li-ion Battery Pack 4Ah 18V (205034)

The compact, powerful all-rounder for maximum power with a lower weight
The Li-HighPower Compact battery pack enables effortless work thanks to weighing under 600 g. It is therefore 20% lighter and 50% more compact than a 5.2 Ah standard battery pack. It saves weight without reducing performance. Because, thanks to the Li-HighPower cell technology, it is powerful enough for any application (for extremely energy-intensive applications or when using AGC 18, HKC 18 or TSC 55 K, we recommend using the Li-HighPower battery pack with 8.0 Ah). Equipped with Bluetooth®, a paired mobile dust extractor starts automatically when the cordless tool is switched on. Additionally, when used in conjunction with the Festool Work app, you can find detailed information about the charge status and operating data, such as the temperature or charge cycles. And, of course, it is fully covered by Festool Service.
