DeWalt XR FLEXVOLT 9.0Ah/3.0Ah 18V/54V Li-ion battery with automatic voltage switching and LED Fuel Gauge

Automatic voltage switching for two tool platforms:

The DCB547 is a single battery that operates at 18V in your existing DeWalt XR power tools and steps up automatically to 54V when inserted into XR FLEXVOLT tools. No manual adjustment is required — the battery detects the tool and switches accordingly. This means one battery pack can cover your full range of DeWalt cordless tools without swapping between different battery systems.

162 Wh capacity with LED Fuel Gauge:

At 18V/9.0Ah or 54V/3.0Ah, the DCB547 delivers 162 Wh of stored energy, giving extended runtime on demanding applications. The built-in LED Fuel Gauge shows remaining charge at a glance so you can plan work around recharging. The battery is compatible with all existing 18V XR chargers — no new charger is needed to use the FLEXVOLT platform.

108V tool power with dual-battery FLEXVOLT tools:

Certain DeWalt XR FLEXVOLT tools accept two DCB547 batteries simultaneously, effectively delivering 108V-equivalent performance for the most demanding site applications. The battery's footprint is the same width and length as a standard 18V XR pack, with only a modest increase in height, so it remains ergonomic in tools that accept it. The included transport cap brings the battery into standard freight and air transport compliance by splitting the 162 Wh rating into three 54 Wh sections.
