Kobalt 48V Max Self-Propelled Mower Extended Runtime Kit

Built for consistent performance and longer run times, the Kobalt 48V Max Self-Propelled Mower Extended Runtime Kit gives you the power to finish your lawn without interruptions. The 48V 21-inch self-propelled mower delivers up to 60 minutes of runtime, making it ideal for properties up to 1/2 acre. Its brushless motor provides strong, gas-free cutting performance, while rear-wheel drive makes it easier to navigate slopes and uneven terrain. The 8-position height adjustment and durable steel-reinforced deck give you control over your cut, while features like push-button start, LED headlights, and vertical storage add everyday convenience. What sets this kit apart is the upgraded battery capacity. In addition to the included mower batteries, you get two 24V 6.0Ah lithium-ion batteries—providing extended runtime and more consistent power across your mower and other tools. Lightweight construction, quick-release design, and built-in diagnostic indicators make them easy to use, while USB-C bi-directional charging adds flexibility for powering devices on the go. Running on Kobalt’s dual 24V system delivering 48V output, this kit is compatible with 100+ Kobalt tools, making it easy to expand your setup. Backed by Kobalt’s 5-year tool and 3-year battery warranties, this kit is built for those who want smoother operation, longer runtime, and the confidence to get the job done in one go.
