DeWalt FLEXVOLT Battery Compatibility
DeWalt FLEXVOLT batteries are dual-voltage: DeWalt says they operate as 18V batteries in 18V (20V MAX) products and as 54V batteries in 54V (60V MAX) products, and that XR FLEXVOLT batteries are backwards compatible with the 18V XR range.
TL;DR
- FLEXVOLT batteries switch voltage with the tool: 18V (20V MAX) in 18V products and 54V (60V MAX) in 54V products (DeWalt).
- DeWalt UK says XR FLEXVOLT batteries are backwards compatible with the entire XR 18V range; its DCB549 page says almost all 18V XR tools and chargers.
- DeWalt’s DCS578/DCS579 54V saw manual lists only FLEXVOLT packs (DCB546, DCB547, DCB548, DCB549); we found no DeWalt statement covering every 54V tool.
- Two FLEXVOLT batteries used in compatible tools deliver 120V operation.
- Compatibility confirmed by the official DeWalt FLEXVOLT system page.
Compatibility Rules
DeWalt says XR FLEXVOLT batteries are backwards compatible with the entire XR 18V range, so any 18V XR tool or charger can be powered by them (its DCB549 page says almost all). In an 18V product the battery operates at 18V; in a 54V product, or a 108V product using two batteries, it operates at 54V.

Charger Notes
DeWalt’s US list names the same 14 chargers for 20V MAX and 60V MAX packs (including the DCB112, DCB115, DCB118 and the four-port DCB104), and DeWalt UK says any XR 18V charger you have can be used. Use a DeWalt charger listed for your pack.

Frequently Asked Questions
Do I need FLEXVOLT batteries for FLEXVOLT tools?
DeWalt’s DCS578/DCS579 54V saw manual lists only FLEXVOLT packs, and FLEXVOLT batteries also work in 18V XR / 20V MAX tools at the lower voltage. We found no DeWalt statement covering every 54V/60V MAX tool.
How does FLEXVOLT switching work?
DeWalt says FLEXVOLT batteries are designed to automatically switch voltages when you change your tool; for example the DCB606 is rated 6.0Ah at 20V MAX and 2.0Ah at 60V MAX. The pages we checked do not describe the internal wiring.
Which FLEXVOLT battery is the best value?
The DCB606 (6.0Ah at 20V MAX / 2.0Ah at 60V MAX) is a common starting point. Larger packs include the DCB609 (9Ah), DCB612 (12Ah) and DCB615 (15Ah), rated at 20V MAX on DeWalt’s US pages.

What is DeWalt FLEXVOLT?
FLEXVOLT is DeWalt’s dual-voltage battery system. DeWalt says the battery operates as an 18V battery in 18V (20V MAX) products and as a 54V battery in 54V (60V MAX) products, and is designed to automatically switch voltages when you change your tool.
How many FLEXVOLT tools does DeWalt make?
We have no verified count of FLEXVOLT tools; check DeWalt’s current FLEXVOLT range. The DCS578 and DCS579 54V saws are examples, and their manual lists only FLEXVOLT packs.
Do FLEXVOLT batteries last long?
We have no DeWalt cycle-life figure. DeWalt rates the DCB606 at 6.0Ah at 20V MAX and 2.0Ah at 60V MAX (the UK DCB546 is 6.0Ah at 18V and 2.0Ah at 54V).
