A dead battery halfway through a downed limb is the single most frustrating moment in storm cleanup. Battery powered chainsaws have evolved far beyond the underpowered trimmers of a decade ago, but choosing the wrong voltage platform or bar length still leaves you stranded mid-cut. The trade-off between instant-start convenience and sustained cutting torque is the central decision every buyer must make.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I’ve spent several seasons analyzing battery platform ecosystems, brushless motor efficiency curves, and real-world cut counts across dozens of cordless saws to separate the tools that genuinely replace gas from those that barely prune a branch.
This guide evaluates nine contenders side by side, focusing on chain speed, bar geometry, and battery architecture so you can confidently pick the right battery powered chainsaw for your property without wasting money on the wrong voltage tier.
How To Choose The Best Battery Powered Chainsaw
A cordless chainsaw is only as good as its battery platform, bar match, and motor type. Jumping on a cheap 20V saw for heavy felling work will leave you frustrated, while buying a 60V pro rig for light pruning wastes cash. Here is what actually matters.
Voltage Class and Battery Platform
Voltage is the single best predictor of sustained cutting torque. 40V saws handle limbing and medium logs up to 10 inches in diameter. 56V and 60V platforms match 40-45cc gas saws, bucking larger timber without bogging down. The platform also dictates future tool compatibility: if you already own a 40V trimmer or blower, sticking with that voltage lets you share batteries across the lineup.
Bar Length and Chain Pitch
Bar length determines the maximum diameter you can cut in a single pass. A 12-inch bar is ideal for pruning and tight spaces, 14-16 inches suits general property maintenance, and 18 inches handles felling and large storm cleanup. Chain pitch (3/8 inch low-profile versus 3/8 inch full) and gauge affect cut smoothness and kickback resistance. Thinner chains cut faster with less drag but wear faster on dirty wood.
Brushless Motor and Chain Speed
Brushless motors deliver more torque per watt and run cooler, extending battery life by 25-40 percent compared to brushed equivalents. Chain speed, measured in feet per second or meters per second, correlates directly with cut aggressiveness. A saw pushing 20 m/s cuts through softwood faster than one at 14 m/s, but higher speed also drains the battery quicker under load.
Safety Features and Maintenance Convenience
Look for an inertia-activated chain brake that stops the chain in under 0.1 seconds during kickback. Tool-free chain tensioning saves time on the job, and a transparent auto-oiler reservoir lets you monitor bar lubrication at a glance. Low-kickback chains and wrap-around hand guards add a layer of protection for less experienced operators.

In‑Depth Reviews
1. Husqvarna Power Axe 350i
The Husqvarna Power Axe 350i is the most complete battery powered chainsaw kit for a homeowner who tackles serious limbing and occasional felling. Its 40V 7.5Ah battery delivers enough capacity to cut through a 2-foot Douglas fir in under a minute, and the Boost Mode adds 25 percent more torque when you hit a tough knot. The X-Cut chain holds its edge significantly longer than standard Oregon chains, which means fewer sharpening sessions across a season of heavy use.
At 7.72 pounds without the battery, this saw feels balanced in hand and produces almost no vibration compared to a gas equivalent. The tool-free tensioning system is easy to operate, though the tensioning mechanism sits behind the bar nut and can be fiddly to access when the bar is removed for cleaning. The included 1A charger takes six to seven hours for a full top-up, so buying a faster charger is advisable if you plan multi-hour cutting sessions.
Riders coming from gas will appreciate the instant electronic start — no pull cord, no choke, no fuel mix. The chain brake engages reliably, and the rubberized grip stays comfortable even in wet conditions. For light commercial landscapers or serious property owners, this kit eliminates the biggest pain point of cordless saws: running out of power before the task is done.
What works
- Boost Mode delivers genuine torque spike when needed
- X-Cut chain resists dulling on dirty wood
- Very quiet operation with low vibration
What doesn’t
- Included charger is slow at 1A
- Plastic tension mechanism can deform under pinch loads
- Replacement batteries are expensive
2. DEWALT FLEXVOLT 60V 18″ DCCS672X1
The DEWALT DCCS672X1 is a torque monster that claims 26 percent more peak power than a 40.9 cc gas chainsaw, and real-world cutting bears that out. The 18-inch bar handles 20-inch hardwood logs without bogging, and the brushless motor delivers sustained torque that rivals a Stihl MS 250. Auto-oiling keeps the chain lubricated continuously, and the onboard wrench for chain adjustment means you never lose a tool in the grass.
Weighing 18.75 pounds with battery, this is a heavier unit, but the weight distribution is excellent and the wraparound handle gives solid control during angled cuts. The FLEXVOLT battery automatically switches from 60V in the saw to 20V when placed in a standard DEWALT charger, making it compatible with the entire DEWALT 20V ecosystem. Chain tension tends to loosen after extended cutting, and some users report the chain derailing if not checked frequently.
Cutting through 15 trees in one six-hour session without overheating is rare for a cordless saw, yet this DEWALT manages it with a single 3Ah battery lasting 1.5 to 2 hours under moderate load. It is quieter than any gas saw by a wide margin, and the lack of idling means you only drain battery when actually cutting. For homeowners already invested in the DEWALT platform, this saw is a no-brainer upgrade.
What works
- Torque output exceeds most 40cc gas saws
- FLEXVOLT battery works across DEWALT 20V/60V tools
- Onboard chain wrench is a practical touch
What doesn’t
- Heavy at almost 19 pounds
- Chain loosens and derails frequently
- Battery drains fast under constant heavy load
3. EGO POWER+ 18″ CS1800
The EGO CS1800 is the gas equivalent of a 45cc chainsaw, producing up to 11,000 RPM at the chain. It delivers up to 300 cuts on a 4×4 with a recommended 5.0Ah battery, which is more than double what most 40V saws claim. The 18-inch bar and 3/8-inch pitch chain with 0.050-inch gauge make it suitable for felling trees up to 16 inches in diameter without struggling.
This saw is sold as a tool-only unit, which keeps the upfront cost lower for users who already own EGO 56V batteries from other equipment. The brushless motor is paired with an LED work light for dusk operations, and the IPX4 weather-resistant construction means you can keep working in light rain. The auto-tensioning knob is well-designed and holds tension better than many competitors, though the chain can still derail if not properly seated after a tension adjustment.
The biggest trade-off is weight: at 9.7 pounds without battery, and with a 5.0Ah battery adding another 2-3 pounds, the total weight exceeds 12 pounds. This is manageable for short sessions but fatiguing for all-day limbing. The automatic oiler works consistently and the spill-free reservoir is a nice touch. For dedicated EGO platform users, this saw justifies itself purely on cut count and gas-like power.
What works
- 300 cuts per charge with 5.0Ah battery
- LED light helps in low visibility conditions
- IPX4 weather resistance for wet cutting
What doesn’t
- Battery and charger not included
- Heavy once paired with large battery
- Chain can derail if not tensioned correctly
4. Caterpillar DG631 60V 18″
The Caterpillar DG631 stands out with a chain speed of 78.7 feet per second, which is faster than most 18-inch battery saws and allows for exceptionally smooth cuts through green and dry wood alike. The Brushless Motor 2.0 claims 40 percent more power and 10 percent longer runtime than standard brushless designs, and the 60V 5Ah battery provides enough stamina for demanding tree care tasks like felling and bucking.
Weighing 13.1 pounds with the battery, the DG631 is lighter than the DEWALT FLEXVOLT and feels more maneuverable overhead. The tool-free chain tensioning system uses a dial that holds adjustment well during sustained cutting. However, some users report that the supplied bar and chain use softer metal that wears quickly, and the chain can develop burrs that increase kickback risk. Replacing the bar and chain with an Oregon aftermarket set resolves this issue and significantly improves cut quality.
The battery and charger are both included, which is rare at this voltage tier, and the batteries are compatible with the entire CAT 60V outdoor power equipment lineup. The inertia chain brake and reduced-kickback bar nose add confidence for less experienced operators. Battery life after repeated charge cycles has been inconsistent in some units, so check the warranty terms carefully before purchasing.
What works
- Very fast chain speed for clean cuts
- Battery and charger included
- Lightweight for an 18-inch saw
What doesn’t
- Stock bar and chain are below average quality
- Battery longevity inconsistent across units
- Oil cap threads prone to stripping
5. EGO POWER+ 16″ CS1611
The EGO CS1611 bridges the gap between budget 40V saws and premium 60V models by offering a 56V platform with a 2.5Ah battery at a mid-range price. The 20 m/s chain speed makes it competitive with 40cc gas equivalents, and the 16-inch bar is long enough for most property maintenance tasks while remaining nimble enough for limbing. It delivers up to 130 cuts on a 4×4 with the included battery, which is adequate for a full weekend of cleanup.
The tool-free chain tensioning system is simple and effective, and the IPX4 weather-resistant construction means it can handle damp conditions without issue. At 9 pounds, it is noticeably lighter than the 18-inch models, making it a better choice for users who need to carry the saw up a ladder or through dense brush. The auto-oiler works well, but the oil reservoir is on the smaller side and needs refilling more frequently during heavy cutting.
Some users report that the chain derails easily if debris gets caught between the bar and chain, which can be frustrating mid-cut. The included 2.5Ah battery is the smallest in the EGO lineup, so upgrading to a 5.0Ah or 7.5Ah battery is recommended if you plan to tackle larger projects. For occasional use around a standard suburban lot, this saw delivers excellent value without the sticker shock of the 18-inch sibling.
What works
- Excellent chain speed for its size
- Lightweight and well-balanced
- IPX4 weather resistance
What doesn’t
- Small oil reservoir needs frequent refills
- Chain derails if debris gets caught
- Battery is undersized for extended work
6. SKIL PWR CORE 40 14″ CS4555-10
The SKIL PWR CORE 40 CS4555-10 solves the runtime anxiety problem with its Auto PWR JUMP charger, which brings the 2.5Ah battery from zero to 30 percent in just 15 minutes. The 14-inch bar is a sweet spot for general yard work, and the digital brushless motor provides 3.5 horsepower equivalent, which is strong for its size. The PWR CORE 40 battery technology wraps each cell with cooling material, extending overall battery life by 2X compared to standard lithium packs.
Tool-free chain tensioning is handled by a convenient side dial, and the auto-lubrication system keeps friction low. The saw includes an anti-kickback brake that cuts power instantly, and the weather-resistant construction adds durability for outdoor storage. At 11.53 pounds, it is heavier than the Greenworks 12-inch but still manageable for most users. The plastic components on the tensioning mechanism feel less robust than metal alternatives, though they have held up well in testing.
Real-world runtime is around one hour of intermittent cutting, which is sufficient for limbing trees after a storm but not for all-day felling. The charger speed means you can work in cycles: cut for an hour, charge for 15 minutes to get back to 30 percent, and repeat. The SKIL 40V platform includes a pole saw that shares the same battery, making this a smart entry point if you plan to expand your cordless tool collection.
What works
- Very fast jump charging from dead
- Cooling tech extends battery lifespan
- Good power-to-weight ratio for 14-inch bar
What doesn’t
- Battery runtime limited to ~1 hour
- Plastic tensioning parts feel flimsy
- Lacks felling marks on the housing
7. Dong Cheng 40V 16″ Brushless
The Dong Cheng 40V 16-inch chainsaw is a heavy-duty performer that delivers gas-like power without the gas price tag. It comes with two 4.0Ah batteries and a charger, giving you a total of 8.0Ah of runtime right out of the box. The brushless motor and dual 20V batteries (series-wired to produce 40V) provide up to 120 cuts on a 4×4, which is impressive for the price tier.
The tool-free chain tensioning knob is externally mounted and allows quick adjustments, while the inertia-activated chain brake stops the chain in under 0.1 seconds. The 16-inch bar is well-suited for felling medium trees and bucking logs up to 14 inches in diameter. The chain speed is rated at 14 m/s, which is slower than premium competitors but still adequate for most homeowner tasks. Some units have shipped with a faulty auto-oiler, so inspect the oil flow before extended use.
The included batteries charge fully in under 20 minutes, which minimizes downtime significantly. The saw is well-balanced and feels lighter than its size suggests, though long-term durability remains unproven with some users reporting issues after a season of heavy use. For budget-conscious buyers who need 16-inch cutting capacity and two batteries, this saw offers tremendous value.
What works
- Includes two 4.0Ah batteries
- Batteries recharge in under 20 minutes
- Powerful enough for felling and bucking
What doesn’t
- Auto-oiler can be faulty out of box
- Long-term durability is uncertain
- Chain speed is lower than competitors
8. Greenworks 40V 12″ CS40B210
The Greenworks 40V 12-inch compact chainsaw is the most portable option in this lineup, weighing just 6 pounds with the battery. It is designed specifically for light-duty tasks like pruning, storm cleanup, and camping use, and the 12-inch low-recoil chain handles branches up to 10 inches in diameter. The 2.0Ah battery delivers up to 50 cuts on a 4×4, which is enough for a weekend of limbing without needing a spare battery.
The dual safety start system (lock button plus trigger) prevents accidental startups, and the tool-free auto-tensioning system adjusts the chain without needing a wrench. The auto-oiler keeps the chain lubricated, and the battery doubles as a USB power bank for charging phones or iPads. The 40V platform is compatible with Greenworks 40V string trimmers, blowers, and hedge trimmers, making it a good starting point for building a cordless tool ecosystem.
The chain tend to loosen during use more frequently than larger saws, requiring periodic retensioning to prevent derailment. It is not designed for felling trees or bucking large logs, and attempting to do so will strain the motor and drain the battery rapidly. For its intended use — light pruning and emergency cleanup — this saw is an excellent lightweight companion that stores easily in a trunk or shed.
What works
- Extremely lightweight at 6 lbs
- Battery functions as USB power bank
- Low-recoil chain for safe pruning
What doesn’t
- Chain loosens frequently during use
- Not suitable for felling or heavy bucking
- Limited to branches under 10 inches
9. DEWALT 20V 8″ DCCS623B
The DEWALT DCCS623B is a one-handed pruning saw with an 8-inch bar that fits in a backpack or tool belt. It is designed for quick limb trimming, clearing saplings, and cutting branches up to 7 inches thick. Running on the DEWALT 20V battery platform, it shares power with the most widely used cordless tool ecosystem in North America. The brushless motor provides surprising torque for its size, and the chain speed is adequate for clean cuts through green wood.
This saw is tool-only, meaning you need an existing DEWALT 20V battery to use it. The 2.8 horsepower rating is misleading for the size, but in practice it cuts through branches up to 7 inches without jamming, as long as the chain is sharp. The small bar makes it ideal for ladder work and tight spaces where a full-size saw cannot fit. The auto-oiler works well, and the chain tensioning is straightforward, though the small chain size means it needs sharpening more frequently than larger chains.
The main limitation is the low RPM and chain speed, which causes the saw to vibrate and jam on branches under 1 inch thick. It also has a tendency to feel underpowered when cutting dense hardwood. For a homeowner who already owns DEWALT 20V batteries and needs a compact saw for minor trimming, this is a convenient addition. For anyone needing a primary cutting tool, the 8-inch bar is too short for most real work.
What works
- Ultra-compact for backpack carry and ladder use
- Shares the ubiquitous DEWALT 20V battery platform
- Surprisingly good torque for an 8-inch saw
What doesn’t
- Slow RPM causes vibration on small branches
- Only useful for pruning, not real cutting
- Battery not included
Hardware & Specs Guide
Voltage and Motor Architecture
Higher voltage directly translates to higher sustained torque and faster chain speed. 40V saws are fine for limbing and storm cleanup but bog down on logs over 12 inches. 56V and 60V saws deliver torque comparable to 40-45cc gas engines, making them suitable for felling and bucking. Brushless motors are mandatory in this category — they run cooler, last longer, and extract 25-40 percent more runtime per charge than brushed alternatives. The controller board in a brushless motor also allows features like Boost Mode or variable speed trigger.
Chain Pitch, Gauge, and Bar Length
Chain pitch (the distance between drive links) affects cut aggressiveness and kickback. Most battery saws use 3/8-inch low-profile pitch, which balances speed and safety. Gauge (the thickness of the drive links) typically ranges from 0.043-inch to 0.050-inch — thinner gauges cut faster but are more prone to derailing. Bar length should match your typical cutting diameter: add 2-3 inches of bar beyond your log diameter to allow the nose to clear. Using a bar that is too short forces you to cut from both sides, doubling the effort.
