I came across what looks to be a new Dewalt 20V Max 5Ah battery with Bluetooth connectivity and Lanyard-Ready tether attachment point.
The battery, model DCB205BTLR, is essentially a standard Dewalt 20V Max 5Ah battery pack that’s built with added features.
Dewalt says that the battery connects to smartphones via their Tool Connect app, for tracking and management purposes, as well as alerts and diagnostics.
The Bluetooth connection is described as forming a secure system, where once a battery is paired to a phone, no other phone in range can pair to it.
The battery also has a Lanyard-Ready tether attachment, which can be used with compatible Dewalt accessories.
Shown above is a Dewalt 20V Max cordless impact driver and battery (non-Bluetooth), both with Lanyard-Ready accessories.
The Bluetooth connectivity and Lanyard-Ready attachment are both specialty features, but essential in certain work environments.
If you don’t need the lanyard or tool tether attachment, a Bluetooth-only version of the 5Ah battery is also available. Acme has the 2-pack for $249.
