Flymo is popular in the mower industry for creating their lightweight compact mowers, such as the hover mowers and speedi mo mowers, however, one of their most compact battery designs of all time is the cordless battery Flymo Mighti Mo Mower 300. 

This Flymo might mo mower has a cordless design and a 1 x lithium-ion battery which is perfect for a smallish garden or the average backyard of a homeowner. The model is also very highly rated and affordable, not to mention incredibly light in weight. 

So to see if this Flymo might mo cordless battery lawn mower is right for you, we have reviewed the cordless mower in more detail below and listed its pros and cons to help you make an informed decision.

Main Features Of The Flymo Mighti Mo 300 Lawn Mower 

As we touched on above, the Flymo mighti mo cordless battery lawn mower has a very lightweight compact product size and is most suitable for small gardens. 

It is also in a nice price range for most people who are looking for a standard lawnmower, so its features below are worth taking a look at. 


The power of this small cordless Flymo lawnmower comes from one battery type 40V 2Ah Li-Ion battery, this battery on charge takes 120 minutes to reach its full capacity then has a running time of 25 minutes once inside the battery lawnmower.

Its battery charger is also included with the battery pack on the model and it can overall cut a garden up to 250 square meters in size in terms of battery duration.

What We Think

This power system included with the cordless battery lawn mower is great for small gardens and has a fair average capacity and charging time considering its low affordable price. 

We do think however this model would struggle with battery performance if your garden is on an incline, and the battery charge time is a little longer than other similar mowers on the market, so you would have to factor this in before mowing. 


As this Flymo cordless mower is very compact, so is the cutting size. The mower comes with metal blades that have a cutting width of 30cm, making it ideal for small lawns only and it has five different cutting height settings to choose from when choosing the height adjustment of your lawnmower. 

The cutting heights of this cordless mower range from 25-65mm which allows you to use the different adjustable cutting heights to mow your lawn short or long according to preference. 

What We Think

For a small garden, the metal blades that come with this Flymo mower are big enough to get the job done and have great height steps to choose from. The lever for changing the cutting heights is also very simple to function and quick. 

[aawp fields="B01MZ6RNWC" value="thumb" image_size="large" image="3"]

You shouldn't use this mower on medium-large gardens as it will take a lot of time and an additional battery with the mower due to the small blade width and capacity. 


Design-wise, the Flymo might mo 300 model is very light weight, weighing a total of just 9.9kg which makes the mower quick and easy to move around without the user getting fatigued. 

Its design is also ergonomic for better comfort and the light weight combined with its foldable handle makes the mower very easy to store away after use. 

What We Think

Overall, for the money, you get a high-quality compact mower that doesn't take up too much space and is easy to carry and move around, however, the long term durability of the model might be questionable if you use it for heavy-duty work on an uneven lawn.

Extra Features 

As this Flymo cordless model is pretty compact, it cannot support extra features such as mulching or a roller, however, the design does have a 30L grass box included for storing grass clippings which is a nice feature. 

[aawp fields="B01MZ6RNWC" value="thumb" image_size="large" image="4"]

The model additionally has a removable safety key safety feature which is great to prevent accidental start-up of the machine from children. 

What We Think

For this models compact size, it is understandable that it doesn't come with some extra features, it's 30L grass box should be sufficient for a small lawn size however and the safety key is great for peace of mind. If you want a mower that comes with a roller or mulching option, then you would need to spend more on a larger mower.
