Corded Power – Cordless Freedom – Dewalt FLEXVOLT

The folks at Dewalt have outdone themselves again, introducing an entirely new line of cordless batteries – coined the FLEXVOLT System. The first of their kind, these Dewalt batteries feature an intelligent design, capable of changing voltage when you change tools. The FLEXVOLT system is compatible with 20V MAX, 60V MAX and 120V MAX tools.

The Dewalt DCB606 20V/60V MAX FLEXVOLT 6.0 Ah battery pack is designed with fifteen 4V MAX cells. Designed to run in either parallel or series mode, this battery is currently the most versatile in its class. In parallel mode, three sets of five cells connect in a parallel circuit. Each set provides 2 Ah (Amp Hour). Keep in mind, Ah is the amount of energy charge in a battery. This mode gives you a total of 20V MAX and 6 Ah for an increased run time.


The FLEXVOLT battery is engineered to run four times longer than a compact 20V MAX battery. To see a quick video demonstration of FLEXVOLT, click here.

The series mode works a bit different. All 15 cells connect in a series to provide power for 60V MAX tools. The DCB606 automatically switches to this mode when you slide it into Dewalt’s 60V MAX brushless tools.


The DCB606 battery pack can power all Dewalt 20V MAX cordless tools, including the DCN693B cordless metal connector nailer (DCN693M1 model if purchased with 20V battery), DCN692B cordless framing nailer (DCN692M1 model if purchased with 20V battery), DCN660B cordless finish nailer (DCN660D1 if purchased with 20V battery), as well as 60V and 120V MAX cordless tools. Additional features on this FLEXVOLT battery include an LED display that shows you the state of charge, single piece cell holder, and durable construction.


For a quick, 60-minute charge of the FLEXVOLT battery, we recommend the Dewalt DCB118 fan-cooled fast charger. This battery charger is compatible with all 20V MAX batteries.


Dewalt has combined the power of corded with the freedom of cordless. Not just convenient, longer run time and more power translates to increased productivity and revenue. The FLEXVOLT system eliminates the constant hassle of charging and recharging your batteries, reducing downtime significantly. The Dewalt DCB606 is now available for pre-order only, with an anticipated release toward the end of August 2016.

      Darren, Dewalt looks to be introducing the FLEXVOLT system across the board, but in small spurts. They have not officially announced any FLEXVOLT specific nailers or staplers yet, but I would think they will come in the future. In the meantime, the 20V cordless system can be used with FLEXVOLT batteries.
