The DeWalt DCB547-XJ XR FlexVolt Battery (18V / 54V 9.0Ah Li-Ion) is a high-capacity power source designed to deliver maximum runtime and professional-grade performance across the DeWalt cordless tool range. Featuring FlexVolt technology, this innovative battery automatically switches between 18V and 54V, allowing it to power both DeWalt XR and XR FlexVolt tools with ease.

Convertible Dual-Voltage Technology

The FlexVolt battery system intelligently adapts to the tool being used. When connected to 54V FlexVolt tools, it provides the high power required for heavy-duty cutting, drilling, and grinding. When used with 18V XR tools, it automatically switches to 18V to deliver extended runtime and compatibility with existing tools.

High-Capacity 9.0Ah Performance

With a 9.0Ah capacity, the DCB547 offers longer working time between charges compared to standard batteries. This makes it ideal for demanding applications where extended runtime is essential.

Backwards Compatible with XR Tools

The battery is fully compatible with the entire DeWalt 18V XR tool range, allowing professionals to upgrade their power source without replacing existing tools or chargers.

Designed for High-Power Applications

The 54V FlexVolt platform delivers significantly higher power for larger cordless tools such as circular saws, grinders, and outdoor power equipment. In some systems, two FlexVolt batteries can be used together to create even higher power output for demanding tasks.

Compact and Practical Design

Despite its increased capacity, the battery maintains similar width and length to standard 18V XR batteries, with only a slight increase in height, ensuring compatibility with most tool designs.
