Festool 578732 18V Energy Set (2x TBX 4.0Ah & TCL 6 Charger)

Get maximum performance without the weight penalty. The Festool 578732 Energy Set is the ultimate starter or expansion pack for your 18V cordless tool lineup. This premium power system features two 4.0 Ah Bluetooth® battery packs that utilise advanced tabless cell technology.

By replacing restrictive terminal tabs inside the battery with a continuous connection, these cells deliver massive, sustained power under heavy loads while generating significantly less heat. Less heat means longer overall battery life and the ability to slide them straight back onto the included TCL 6 Rapid Charger without waiting for a cooling-off phase. Lightweight at just 600 grams per battery, it keeps you working productively and fatigue-free all day long.
