DeWalt DCB549 54v XR Cordless FLEXVOLT Li-ion Battery 15ah
The DeWalt DCB549 54v XR Cordless FLEXVOLT Li-ion Battery 15ah is a convertible power solution designed for demanding construction applications. This innovative battery represents a breakthrough in cordless technology, automatically switching between 18V and 54V depending on the tool it powers.
The FLEXVOLT system provides tradespeople with exceptional versatility across their toolkit. The 15.0Ah capacity delivers extended runtime for heavy-duty construction equipment whilst maintaining full compatibility with the existing range of DeWalt XR 18V products. This eliminates the need for separate battery platforms, streamlining tool management on site.
Ideal for professionals running high-demand power tools such as large angle grinders, circular saws and breakers, this battery significantly outperforms standard 18V XR 4.0Ah or 5.0Ah batteries. The integrated charge indicator allows quick status checks without interrupting workflow, helping contractors maintain productivity throughout the working day.

• World's first convertible 18/54V battery offering unprecedented power levels
• 15.0Ah capacity provides extended runtime for demanding applications
• Full compatibility with existing DeWalt XR 18V product range
• Integrated charge indicator for quick battery status monitoring

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
DeWalt Flexvolt
DeWalt 54v Flexvolt is the new DeWalt dual voltage system. A 54v Tool can only use 54v batteries, however your new DeWalt 54v Flexvolt battery is fully compatible with all DeWalt 18v Li-ion Power Tools as it is capable of stepping into 18v mode for this purpose.
So upgrading to 54v means you can still make use of your 18v power tool range. 54v batteries are currently available in:
6ah (18v mode) / 2ah (54v mode)
9ah (18v mode) / 3ah (54v mode)
12ah (18v mode) / 4ah (54v mode)
The DeWalt Flexvolt system opens the door to types of tool becoming available in cordless that would never have been considered before such as Table Saws.
