60V vs 80V Chainsaw: Which Fits Your Woodpile? (2026)

Side by side

Ranges are typical of the listings reviewed; example figures are manufacturer rated, collected 20 October 2026.

60v vs 80v chainsaw: voltage and bar length

The 60V side: the Sihuird states a 60V 16-inch bar with 2x 60V 4.0Ah batteries and a brushless motor, and the SENIX states a 60V 16-inch Oregon bar with a 4.0Ah battery. The 80V side: the Greenworks states an 80V 18-inch bar with a 4.0Ah battery, brushless, with a stated 50CC gas equivalent. Bar length favors the 80V pick at 18 inches; the 60V pair sit at 16 inches.

Chain speed

The Sihuird states 42.58 ft/s chain speed with three levels of power regulation. The SENIX states 85 ft/s chain speed, the fastest stated here, with an ECO mode for energy efficiency. The Greenworks states no chain speed figure, so the listings give no basis for comparing chain speed across voltages.

Batteries and runtime

The Sihuird includes two 60V 4.0Ah batteries with a stated 400 cuts on 4×4 lumber on a single charge. The SENIX includes one 60V 4.0Ah battery with a charge indicator, and states the brushless motor extends runtime 30 percent versus conventional tools. The Greenworks includes a 4.0Ah battery and charger with no runtime figure stated. The Sihuird is the only one of the three that states two batteries in the box.

Safety features

The Sihuird states an instantaneous stop chain brake for added safety. The Greenworks states a mechanical chain brake for added safety and reduced risk of injury. The SENIX states no brake figure. All three state automatic oiling: the Sihuird with a transparent oil window, the SENIX with a larger oil capacity, and the Greenworks with an automatic oiler.

Warranty

The Sihuird states a 3-year tool warranty with a 2-year battery warranty. The SENIX states a 5-year tool warranty with a 3-year limited warranty for battery and charger, the longest stated here. The Greenworks states no warranty term. For warranty length, the SENIX is the stated leader.

The saws

How we scored them

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Chain speed: 42.58 versus 85 ft/s

The two 60V saws state very different chain speeds, and the 80V states none. The SENIX lists 85 ft/s ultra-high chain speed, which it calls the fastest in its class. The Sihuird lists 42.58 ft/s, which it also calls the fastest in its class. Both claims cannot hold at once: read each as the maker’s own statement, and the stated figures as the comparison. The Greenworks lists no chain speed figure, only the 80V platform and brushless motor with 2 times more torque and power equivalent to a 50CC gas engine.

The Sihuird adds three levels of power regulation to its speed figure, which the listing positions for professional arborists, loggers and experienced DIY users. The SENIX adds an ECO mode for energy efficiency on delicate pruning tasks. For firewood cutting, the stated speeds are the comparison; for pruning, the SENIX’s ECO mode is the stated efficiency feature.

Runtime and battery claims

Battery configurations differ. The Sihuird includes 2 60V 4.0Ah batteries with a charger and states up to 400 cuts on 4×4 lumber on a single charge. The SENIX includes one intelligent 60V 4.0Ah battery with a charge indicator and a charger, and states its brushless motor extends runtime 30 percent over conventional tools. The Greenworks includes one 4.0Ah battery and a charger with no stated cut count.

Two batteries against one is the practical difference: the Sihuird’s second pack keeps the saw running while the first charges. The SENIX’s charge indicator is the stated convenience the others do not name. Warranty terms on the power side: the Sihuird states a 3-year tool warranty with a 2-year battery warranty, and the SENIX states a 5-year tool warranty with a 3-year limited warranty for battery and charger. The Greenworks states no warranty term.

Bar length and stated uses

The 60V pair are 16-inch saws and the 80V is 18 inches. The SENIX states a 16-inch Oregon bar for tree pruning and branch trimming. The Sihuird states its 16-inch saw for tree and wood cutting. The Greenworks states its 18-inch saw for tree felling, firewood cutting, storm cleanup, limbing and pruning. For firewood specifically, the Greenworks names firewood cutting in its stated uses; the Sihuird names wood cutting and the SENIX names trees, limbs and firewood in its item type name.

Weight is stated on two: the SENIX at 14 pounds and the Greenworks at 4.3 kilograms, with the Sihuird stating 20 by 10 by 10 inches but no weight. The Greenworks at 35.43 by 8.58 by 9.09 inches is the longest stated body, which fits the 18-inch bar.

Tensioning and oiling

All three state automatic oiling and easy tensioning. The Sihuird states tool-free chain tensioning with an automatic oiler and a transparent oil window. The SENIX states tool-free tensioning with automatic oiling and a larger oil capacity for continuous cutting. The Greenworks states side-access tensioning with an automatic oiler. The oil window on the Sihuird is the only stated level check; the SENIX’s larger oil capacity is the only stated capacity claim.
