How should I store the battery if I won’t be using it for a long time in WINTER?

Before long-term storage, charge the battery to 70% (3 indicator bars) and store it in a cool, dry place (0–35°C / 32–95°F), away from heat and sunlight.

Lithium batteries self-discharge 2–5% monthly—avoid full discharge to prevent permanent damage.

What’s the difference between the S1 2WD and 4WD models?

The S1 2WD is designed for flat to moderate lawns, handling slopes up to 45% (24°).

The S1 4WD is built for steep terrain, handling slopes up to 75% (37°) with standard tires, 85% (40°) with wide tires, and 100% (45°) with deformable tires.

Is there a difference in cutting height between the S1 2WD and 4WD?

Yes.

The S1 4WD offers a cutting height range of 1.5–4.3 inches, and it can handle grass up to 51 inches in height.

The S1 2WD has a cutting height range of 1.8–4.6 inches, and it is suitable for grass up to 28 inches in height.

How long does the battery last, and how much area can the S1 mow?

18Ah battery: ~2h 15min runtime, up to 1.125 acres; charges in ~90 min.

12Ah battery: ~1h 30min runtime, up to 0.75 acres; charges in ~70 min.

Actual runtime depends on blade type, grass height, and terrain.

How safe is the S1 remote lawn mower?

The S1 is designed with safety in mind: it has 4 ultrasonic sensors to avoid collisions, a front bumper for extra protection, and sensors that slow and stop the blades if the mower tilts or flips.
