ITS Expert Says

This is your ticket to the Dewalt FLEXVOLT 56V range of cordless tools.

FLEXVOLT Batteries can be used in both 18V tools and 56V tools. When used in 56V tools the Ah (runtime) is reduced compared to when used with an 18V tool.

Product Description

The FLEXVOLT Dewalt DCB546 54v 6.0Ah Lithium-ion Battery is a true game changer.

The incredible new bit of technology is a huge jump forward for Dewalt and there already impressive range of cordless power tools. FLEXVOLT XR is a new range of cordless tools, batteries and chargers which are based on a 54 volt lithium-ion battery platform. All the tools on the FLEXVOLT platform are going to be top of the range, 54v, cordless and brushless giving you incredible runtimes, unrivaled power and increased capacities across the board.

This battery the FLEXVOLT DCB546 is the same length and width as the 18v Li-ion batteries from the original XR range, with a little extra height to fit in those additional 38 volts of power. Its not only a similar size and weight to the 18v batteries, but its also fully compatible with the entire 18v range! So yes, you can use the FLEXVOLT battery with your normal 18v XR range tools. To achieve this Dewalt have given it a special limiter on it to make sure that when you connect it to an 18v tool, it only transmits 18 volts so you won't damage your tools.

It can also be charged by any 18v XR charger that you may already have! - Charge times TBC!

The DCB546 is a 6.0Ah battery which will give users increased runtime over any of the 18v XR 4.0Ah or 5.0Ah lithium batteries.

Features we love


    XR FLEXVOLT is a range of 54V power tools that offer runtime and performance which has never been seen before - for the first time, professionnal tradesmen can reliably undertake heavy-duty construction applications without the need for mains power.

    This innovation means that you can have 54V power across a whole range of tools without the inconvenience of a cable. DEWALT XR FLEXVOLT is the only battery on the market that can switch from 54V to 18V, making it backward-compatible with your existing XR powertools.

    However you are unable to put an 18V battery on a FLEXVOLT tool as it will not have enough power to run it a FLEXVOLT Tool
