Go cordless with BLACK+DECKER 20V MAX POWERCONNECT

Meet the LB2X4020-OPE 4Ah lithium battery, part of BLACK+DECKER's expansive 20V MAX POWERCONNECT ecosystem. This module is designed to work across the range, letting you move from saw to sander, hedge trimmer to leaf blower, with fewer interruptions and more freedom.

Power tool users appreciate the balance of runtime and weight. The 4Ah rating delivers substantial capacity for longer sessions, while compact 1.5Ah and 2Ah options (sold separately) give you lighter choices for quick tasks. The lithium-ion cells maintain steady power so you can focus on the job at hand rather than power levels.

Smart protection is built in. Onboard electronics monitor voltage and temperature to guard against overload and help extend overall life. The durable housing resists impact, so the battery stands up to the bumps and knocks that come with home projects or yard work.
