A "cordless brush cutter 21V" refers to a battery-powered brush cutter that uses a 21-volt lithium-ion battery system. These tools are increasingly popular for garden and landscaping tasks due to their convenience, lower noise, and reduced emissions compared to gasoline-powered models.
Key Features and Specifications (Typical for 21V Cordless Brush Cutters):
Voltage (21V): This indicates the power of the battery. 21V (often marketed as 20V or 21V Max) is a common voltage for handheld cordless garden tools, offering a good balance of power and battery life for light to medium-duty brush cutting and trimming.
Battery Type: Typically uses Lithium-Ion (Li-ion) batteries. Li-ion batteries offer:
Good power output.
Longer runtimes compared to older battery technologies.
No memory effect (can be charged at any time without damaging the battery).
Relatively fast charging.
Battery Capacity: Measured in Amp-hours (Ah). Common capacities for 21V brush cutters are 2.0Ah, 4.0Ah, or even higher (e.g., 20,000mAh, which equals 20Ah, though actual usable capacity might be lower for compact tools). Higher Ah means longer runtime. Many models come with two batteries for extended use.
