Tired of pulling a starter cord at 7 a.m. while the neighbors are still sleeping? I get it. Battery mowers have grown up fast, and the right pick can handle a typical suburban lot on a single charge, fold flat for storage, and start with the push of a button. Whether you’re trading a gas mower that’s been complaining for years or buying your first mower for a townhouse patch of grass, the six models below cover everything from tiny courtyards to quarter-acre lots with attitude.
A Side-By-Side Look
Greenworks 80V 21in Push Lawn Mower
Casince 17in Cordless Walk Behind Mower
EGO POWER+ LM2135SP Self-Propelled Mower
Honda HRX-BE 21in Battery Mower (HRX217YXBEXA6)
Honda HRX-BV 21in Battery Mower (HRX217YXBVKA4)
Litheli 40V 16in Cordless Brushless Mower
Taking A Closer Look At The Options
The Greenworks 80V feels like the gas mower alternative people keep asking me about. Its 21-inch steel deck is the same width you’d find on a basic self-propelled gas unit, so you cover wide swaths without doubling back.
A brushless motor (the kind that uses electronic magnets instead of carbon brushes) keeps it quieter and helps the internals last longer with little routine maintenance. You get an 80V 4.0Ah battery and a rapid charger that tops off in around 60 minutes, with a stated runtime close to an hour under light conditions.
Real Benefits
- Wide 21-inch steel deck finishes typical suburban lots quickly
- Brushless motor runs quieter and tends to outlast brushed designs
- Single-lever height adjustment makes setting changes fast
- 60-minute rapid charger means short turnaround between sessions
- Stated runtime near one hour covers most half-acre lawns
Things To Consider
- Push-only design, so steep hills will wear you out faster than the self-propelled EGO later in this list
- Steel deck adds weight compared to plastic-deck rivals, which may bother some users
- Performance in thick, wet grass can dip as the battery drains
Quick Facts
Best Suited To
Homeowners with flat, medium to large lawns who want gas-like cutting width without the noise or maintenance.
Consider Something Else When
Anyone managing sloped terrain should look at the EGO POWER+ LM2135SP, since its self-propelled drive handles hills with far less effort.
Casince’s 17-inch walk-behind sits in that sweet spot between toy and tool. The narrower deck helps you slip between garden beds and tight side yards where a 21-inch unit would scalp your petunias.
It runs on two 20V 4.0Ah batteries working together, and six height settings from roughly 1 to 3 inches give you flexibility for everything from sparse summer lawns to thick spring growth.
Everyday Advantages
- 17-inch deck navigates narrow side yards and gated areas
- Dual 20V batteries extend runtime up to around 40 minutes
- Six height settings suit different grass types and seasons
Room For Improvement
- Narrower deck means more passes on larger lawns, which can wear you out
- Battery runtime is shorter than the Greenworks and Honda options
- Build quality leans toward lightweight, so owners commonly report careful handling around rough terrain
Right Fit For
First-time mower owners with small to mid-size yards under about 5,000 square feet who want a simple, low-cost entry into cordless mowing.
Look Elsewhere When
Anyone with a half-acre lot will prefer the Greenworks 80V, whose wider deck and longer runtime finish the job in fewer passes.
This is the one I point people toward when they say “I want a real mower, just quieter.” The EGO POWER+ LM2135SP is self-propelled, meaning the rear wheels drive themselves, so you guide rather than push. That alone changes how mowing feels on anything but flat ground.
The 56V 7.5Ah battery pairs with a Select Cut multi-blade system offering three interchangeable lower blades for mulching, bagging, or extended runtime. You also get a bonus 5.0Ah battery (ships separately), which keeps a spare charged and ready.
A Strong Showing
- Self-propelled drive cuts fatigue on slopes and larger lawns
- Three-blade Select Cut system adapts to mulching, bagging, or runtime needs
- Two batteries in the bundle extend working sessions significantly
- Torque output reportedly rivals small gas engines
Points To Keep In Mind
- Premium positioning pushes it past the Greenworks on price
- Bundle ships in multiple packages, so the extra battery may arrive separately
- Heavier than push-only models, though the self-propelled drive offsets that

Made For
Homeowners with sloped or uneven lawns who want the closest battery-powered experience to a premium gas mower.
Swap It Out When
If you mow a tiny, flat patch and don’t need self-propelled drive, the Litheli 40V is a lighter, simpler alternative.
Honda’s HRX-BE brings the brand’s reputation for engines into the battery world with its 4-in-1 Versamow system. That setup uses a Clip Director knob to switch between mulching, bagging, discharging, and leaf shredding without swapping attachments.
Power comes from a Honda-built motor designed to match the torque of the GCV gas series, so the cutting feel should feel familiar to anyone moving away from gas. The 21-inch deck handles the same lawn sizes as the Greenworks.
The Helpful Details
- Versamow system with Clip Director eliminates attachment swaps
- Leaf shredding mode handles fall cleanup without a separate tool
- Honda motor targets gas-equivalent torque for tough grass
Trade Offs
- Push-only drive means you’ll work harder on hills than with the EGO
- Heavier overall build may complicate storage in tight sheds
Quick Technical Notes
Perfect Match For
Year-round lawn caretakers who mow in spring, bag in summer, and shred leaves in fall without juggling extra accessories.
Reach For A Different Pick When
Anyone dealing with steep slopes will appreciate the self-propelled drive on the EGO POWER+ LM2135SP more than this push-only Honda.
The HRX-BV is the BV variant of Honda’s HRX line, which adds variable speed control to the Versamow system. Instead of one walking pace, you can dial the speed to match your stride and the grass conditions, which sounds small until you’ve pushed a mower through thick St. Augustine at the wrong speed.
Like the BE version, it uses a Honda-built motor tuned to mirror the torque curve of the GCV gas engines, paired with the same 4-in-1 Clip Director for mulching, bagging, discharging, and leaf shredding.
Strong Points
- Variable speed matches pace to grass thickness and personal stride
- Same Versamow versatility as the BE model for year-round use
- Honda motor targets gas-comparable performance
Honest Caveats
- Sits at the higher end of the lineup in terms of cost
- Still a push design, so very steep terrain remains a workout

Whose Shelf It Belongs On
Mowers who want fine control over pace and prefer premium Honda engineering for mixed seasonal lawn work.
Where A Sibling Pick Shines
If you don’t care about variable speed and want a simpler, lower-priced Honda option, the HRX-BE delivers the same Versamow system without the extra dial.
Litheli’s 16-inch mower is the smallest in this lineup, and it shows in the best ways. The compact deck slides into narrow side yards and stores vertically in sheds where a 21-inch unit would dominate the floor.
It uses two 5.0Ah batteries together to maintain 40V output during the cut, and six height settings between 25 and 75mm handle most lawn preferences. A 50L collection bag keeps clippings contained for tidy disposal.
Everyday Wins
- 16-inch deck fits tight spaces and stores compactly
- Dual 5.0Ah batteries keep voltage steady under load
- Brushless motor requires minimal routine upkeep
- 50L bag reduces how often you stop to empty
Small Caveats
- Smaller deck means more passes on larger yards, so size up for big lots
- Plastic construction feels lighter, though the brushless motor helps with longevity
Who Should Grab It
Townhouse or apartment-adjacent lawn owners with under 2,000 square feet and limited shed space.
Not Your Match When
Anyone managing a quarter-acre lot will save time with the wider Greenworks 80V instead.
What Matters Most Before Choosing Cordless Electric Lawn Mowers
Yard Size and Deck Width Deck width drives how many trips you make across the grass. A 16-17 inch deck handles tight lots under roughly 2,000 square feet, while 21-inch decks feel more efficient past the 5,000-square-foot mark. Match the deck to your lot, not the other way around.
Battery Runtime and Voltage Voltage matters for cutting power (especially in thick grass), while amp-hour (Ah) ratings indicate how long the mower runs. Higher voltage handles dense growth with less bogging, and dual-battery setups let you swap packs for longer sessions.
Push vs. Self-Propelled Self-propelled mowers drive the rear wheels for you, which matters on any slope you wouldn’t walk up easily. Flat lawns under a quarter acre rarely need that help, but hilly yards transform the experience.
Cutting Modes and Maintenance Look at how the mower handles clippings: bag, mulch, side discharge, or leaf shred. Brushless motors (electronic, no carbon brushes) skip the brush replacements brushed motors need, which is one less chore on the calendar.
Smart Considerations Across These Picks
Pitfalls Shoppers Hit
The most common mistake I see is matching a tiny deck to a large lawn, leading to endless passes and drained batteries before the job is done. Another trap is ignoring deck material, where steel stands up to dings but adds weight, and plastic stays light but can crack against hidden rocks.
What The Higher Tier Buys
Premium models like the EGO POWER+ and Honda HRX-BV add self-propelled drive, variable speed, and multi-mode cutting systems that handle seasonal changes without extra accessories. You pay for less fatigue and more flexibility, which matters most on larger, more varied lawns.
Frequently Asked Questions
How long do cordless electric lawn mower batteries last per charge? Most batteries in this category run between 30 and 60 minutes per charge under typical conditions. Runtime drops noticeably in thick or wet grass, so plan for shorter sessions during heavy growth periods.
Can cordless electric lawn mowers handle thick or wet grass? Higher-voltage models like the Greenworks 80V and EGO POWER+ 56V systems handle thick grass much better than lower-voltage options. Wet grass still challenges any mower and is best left for drier days.
Are cordless electric lawn mowers powerful enough for large lawns? A 56V or 80V mower with a 21-inch deck can handle half-acre lawns, especially with a spare battery on hand. Smaller 16-17 inch decks work better for compact lots.
How long do the batteries themselves last before replacement? Lithium-ion mower batteries typically last 3-5 years depending on storage conditions and charge habits. Keeping them in a garage rather than a hot shed extends their life noticeably.
Do cordless electric lawn mowers need much maintenance? Brushless motors eliminate brush replacements, and there are no oil changes or spark plugs to worry about. Blade sharpening once or twice per season and keeping the deck clean are usually enough.
Final Verdict
A cordless electric lawn mower is one of the easiest upgrades a homeowner can make. The Greenworks 80V covers most needs with confidence, the EGO POWER+ LM2135SP handles slopes without complaint, and the Litheli fits where storage is tight. Match the deck and battery to your lot, pick the features you’ll actually use, and the rest takes care of itself.
