Ditching Gas Without Sacrificing Cutting Power
Battery technology has evolved rapidly over the past few years. High-voltage cordless chainsaws operating between 36V and 80V now deliver torque comparable to 40cc-50cc gas-powered saws. For landowners, homeowners with wood stoves, and storm cleanup response, battery power offers immediate starting, zero engine maintenance, low noise, and zero direct emissions.
To tackle heavy yard work—such as felling mature trees, bucking logs over 12 inches in diameter, or clearing dense hardwood debris—you need more than a light trimming saw. You need high chain speed, sufficient bar length, and an efficient brushless motor. Below is an evaluation of five top high-voltage cordless chainsaws capable of handling demanding wood-cutting tasks.
What to Look For in Heavy-Duty Battery Chainsaws
- Voltage and Power Platform: Higher voltage (36V to 80V) allows the saw to pull heavy amp loads without overheating the motor, maintaining continuous cutting speed under heavy resistance.
- Bar Length: An 16-inch to 18-inch guide bar is ideal for heavy yard work, accommodating logs up to 28–32 inches using double-pass cuts.
- Chain Speed & Pitch: Look for chain speeds above 15 m/s (meters per second) paired with a standard 3/8-inch Low-Profile or .325-inch pitch chain for efficient wood removal.
- Battery Capacity (Amp-Hours): Heavy cutting drains power quickly. Look for 4.0Ah to 6.0Ah batteries to ensure reasonable runtimes while bucking large logs.
Top 5 High-Voltage Battery Chainsaws Reviewed
1. EGO Power+ CS1800 (56-Volt)
The EGO Power+ CS1800 sets a benchmark for cordless performance with its 18-inch bar and high-efficiency brushless motor, delivering power equivalent to a 42cc gas engine. Operating at 20 m/s chain speed, it cuts through dense hardwoods like oak and maple with minimal drag. Key features include an auto-tensioning system and built-in LED headlights for low-light storm cleanup.
Best for: Homeowners needing an all-around heavy-duty saw with standard 18-inch capacity.
2. Stihl MSA 220 C-B (36-Volt AP System)
Stihl’s 36V commercial-grade AP system powers the MSA 220 C-B. Equipped with a 16-inch Light 04 bar and a full-fledged 3/8" PS3 full-chisel saw chain, this saw delivers exceptional cut quality and rapid wood chip clearance. While its nominal voltage rating (36V) appears lower than others, its commercial-grade current output puts its cutting performance on par with 45cc professional gas saws.
Best for: Demanding landowners and woodcutters seeking commercial-grade durability.
3. DeWalt 60V MAX FLEXVOLT (DCCS670)
Built on DeWalt's 60V MAX system, the DCCS670 delivers immense peak torque. It features a 16-inch bar (upgradable to 18 inches) and tool-free chain tensioning. Its brushless motor handles heavy load pressure without stalling, making it popular for cutting heavy firewood rounds and fallen structural limbs.
Best for: Users already on the DeWalt 20V/60V FlexVolt battery ecosystem.
4. Greenworks Pro 80V 18-Inch (GCS80420)
Operating on high 80-volt architecture, the Greenworks Pro provides rapid acceleration and high chain speed (24 m/s max). Its high voltage allows it to cut smoothly through thick logs without bogging down, offering up to 150 cuts on 4x4 timber with a standard 2.0Ah battery (upgradable to 4.0Ah for heavy bucking).
Best for: Maximum voltage output and fast cutting speed at a competitive price.
5. Milwaukee M18 FUEL 16-Inch (2727-20)
The M18 FUEL chainsaw leverages Milwaukee’s REDLINK PLUS intelligence and High Output batteries to generate torque comparable to 40cc gas saws. It reaches full throttle in under one second and holds speed under heavy loads, making it extremely reliable for limb clearing and log bucking.
Best for: Tradespeople and landowners invested in the Milwaukee M18 battery system.

Frequently Asked Questions
Can a battery chainsaw cut large firewood logs continuously?
Yes. High-voltage models (56V to 80V) equipped with 4.0Ah to 6.0Ah batteries can efficiently buck logs 12 to 16 inches in diameter. For continuous, multi-hour cutting, keeping a second charged battery on standby is recommended.
Do battery chainsaws require bar and chain oil?
Yes. Battery chainsaws use the same guide bars and chains as gas models and require continuous lubrication from standard bar and chain oil to prevent friction heat and premature chain stretching.
