Ryobi 36V Brushless 35cm Chainsaw 4Ah Kit RCS36X4
Exact-kit product image.
The RCS36X4 packages the RCS36B1 brushless saw with a 4Ah battery and 1.7A charger. Its 35cm-class bar and 21m/s chain speed give it more cutting headroom than the 18V pick. It remains a homeowner saw that needs sharpening, chain oil and careful maintenance, rather than a substitute for professional tree work.

Extended product analysis
Cutting performance
Choose this kit when garden work regularly goes beyond small branches. Its faster chain and longer bar make it the more useful of these two for preparing manageable firewood and clearing fallen limbs at ground level. Chain speed alone does not measure cutting force or guarantee a clean cut in dense hardwood. Let a sharp chain work at its own pace; sustained large-log processing is a poor match for a single-battery domestic kit.
Battery and charging
It uses RYOBI’s 36V garden platform, not 18V ONE+ batteries. Ryobi claims up to 40 cuts through 100mm branches with the supplied 4Ah pack, but this is a demonstration under stated conditions, not a promised afternoon of cutting. Timber hardness, log diameter, chain condition and temperature change the result. The 1.7A charger is better suited to jobs with breaks than rapid back-to-back battery changes; an extra compatible pack adds to the ownership cost.
Handling and upkeep
At 4.2kg before fitting the battery, it asks more of your arms than the smaller 18V saw. Consider how that weight will feel while repositioning between cuts, not just when lifting it from the shed. Tool-free tensioning makes routine adjustments convenient, while adjustable automatic oiling helps maintain lubrication. Neither removes the need to check tension and oil, sharpen the chain and clear debris. Remove the battery before maintenance and follow the supplied manual’s brake checks.
Who it suits
The $549 kit is easiest to justify for regular domestic cutting or a household already committed to the 36V platform. Allow for bar oil, protective equipment and eventual chain replacement. Oil management and cleaning matter in storage as well as during use; convenient electric starting does not make the saw maintenance-free. Choose the lighter value pick for occasional pruning. For large, leaning or storm-damaged trees, use a qualified arborist rather than treating the longer bar as permission to attempt the job.
Pros
- 21m/s manufacturer-rated chain speed
- Versatile 35cm-class bar
- 4Ah battery and charger included
- Tool-free tensioning; adjustable oiling
- Eligible Australian exact-kit rating pool
Cons
- 4.2kg before adding the battery
- Slow 1.7A supplied charger
- 36V packs do not fit 18V ONE+ tools
- One 4Ah pack limits continuous work
- Bar oil, sharpening and cleaning still required

Ryobi 18V ONE+ HP Brushless 30cm Chainsaw 4Ah Kit RCS1830BLX4
Exact-kit product image.
The RCS1830BLX4 includes the OCS1830BL saw, a 4Ah ONE+ battery and 1.5A charger. Its 304mm bar, brushless motor, automatic oiling and tool-free tensioning cover useful domestic jobs for less money than the 36V kit. The compromise is slower cutting and less headroom when timber becomes thicker or harder.
Specifications
| Power platform | 18V RYOBI ONE+ HP; brushless motor |
|---|---|
| Guide bar | 12-inch / 304mm nominal (30cm class) |
| Chain speed | 10m/s, manufacturer specification |
| Included battery / charger | One 18V 4Ah battery; 1.5A charger |
| Tool-only weight | 3.2kg, excluding battery |
| Chain dimensions | 3/8-inch pitch; 0.043-inch gauge; 45 drive links |
| Chain tensioning | Tool-free, side-mounted adjustment |
| Lubrication | Automatic chain oiling; bar oil sold separately |

Extended product analysis
Cutting performance
This is the more sensible starting point for occasional pruning, garden maintenance and preparing a small amount of firewood. The 304mm bar is useful without making the saw unnecessarily bulky, but its 10m/s chain speed means patience matters in hard timber. Bunnings describes logs up to 200mm, whereas Ryobi quotes a 250mm capacity. Those different claims should encourage conservative job selection, not an assumption that every log near the limit is appropriate.
Battery and charging
The included 4Ah battery works within the 18V ONE+ platform, which improves value if you already own compatible tools. Ryobi’s claim of up to 35 cuts through 100mm timber is not continuous runtime. Larger cuts, a dull chain and demanding timber reduce what one charge can accomplish. The 1.5A charger is modest; plan pauses rather than expecting fast turnaround. Keep battery-temperature limits in mind and stop to investigate if the saw repeatedly shuts down instead of forcing the cut.
Handling and upkeep
At 3.2kg without its battery, it is one kilogram lighter than the 36V saw before packs are fitted. That is a practical advantage when moving around a garden, although it still needs two hands, stable footing and appropriate protective equipment. The side-mounted tool-free tensioner simplifies checks, and the automatic oiler supplies lubricant during cutting. You must still add the correct bar oil, keep the chain sharp and clean out accumulated debris with the battery removed.
Who it suits
At $339 for the complete kit, it suits an occasional user who would otherwise pay separately for a battery and charger. Existing ONE+ owners also gain another compatible pack. Oil leakage in storage and heat under sustained load are reasons to follow the manual’s storage and duty guidance, not grounds to promise fault-free ownership. Choose the 36V kit for more frequent firewood work; skip both if you need all-day large-log output or professional felling capability.
Pros
- Lower-priced complete 4Ah kit
- 3.2kg tool-only weight
- Shares the 18V ONE+ platform
- Brushless motor; tool-free tensioning
- Eligible Australian exact-kit rating pool
Cons
- Slower 10m/s chain speed
- Not suited to repeated heavy firewood work
- Slow 1.5A supplied charger
- One battery; demanding cuts shorten runtime
- Bar oil and chain maintenance still required

What matters when buying a cordless chainsaw
Buying advice
Bar length and workload
Match the bar to timber you can handle safely, rather than buying the longest available. Bar length is not a safe maximum log diameter; a larger saw adds weight and kickback exposure.
Comparing performance claims
Chain speed alone does not establish cutting performance. Compare cut-count claims only when timber species, diameter, battery, chain condition and test method match. Dense Australian hardwood can place much greater load on a saw than softwood.
Battery-system costs
Compare the complete system price, including compatible batteries, charger and replacement parts. A tool-only offer is useful value only if you already own suitable packs. Voltage is not a safety rating: every full-size chainsaw can cause severe injury.
Chain brake
An inertia/manual chain brake is an important full-size-saw feature. A front hand guard should not be assumed to provide a confirmed inertia brake unless the exact model specifies it.
Chain tension
Check tension before use, after initial running and as the chain warms or stretches. A chain that is too loose or too tight is unsafe. Follow the exact manual and remove the battery before adjustment.
Ongoing upkeep
Cordless eliminates fuel mixing, not maintenance. Budget for appropriate bar oil, replacement chains and sharpening, and check local parts support before choosing a platform.
Chainsaw safety boundary
Use eye and hearing protection, appropriate gloves, long trousers, sturdy footwear and chainsaw chaps where appropriate. Keep both hands on a rear-handle saw and maintain a clear work zone. New users undertaking substantial work should seek formal instruction.
Large, leaning or storm-damaged trees, work near buildings or powerlines, major dead limbs and any job requiring climbing belong with a qualified arborist. This guide does not provide advanced felling, notch, back-cut or climbing instruction.
Which one should you buy?
Choose the Ryobi RCS36X4 for the best domestic balance: its 35cm bar, 21m/s speed, complete 4Ah kit and mature evidence suit regular pruning, medium logs and firewood.
Choose the Ryobi RCS1830BLX4 when price, lower weight and ONE+ compatibility matter most, and your jobs stay in the pruning-to-modest-firewood range.
How we chose
Detailed methodology
We assessed current Australian exact models from Ryobi, Stihl, Husqvarna, Makita, DeWalt, AEG and credible lower-cost alternatives. We compared availability, kit-versus-tool-only pricing, bar length, chain speed, manufacturer cut capacity, battery size, chain brake, oiling, tensioning, ergonomics, owner evidence, warranty, parts and platform support, Australian hardwood suitability and value. Worth Buying Australia did not physically cut or laboratory-test timber with these saws.
Frequently asked questions
Is a cordless chainsaw powerful enough for firewood?
Yes, for many domestic workloads. The 35cm-class Best Overall pick is the stronger of these two for regular domestic firewood. Sustained large-log or professional forestry work remains a different workload, especially in dense Australian hardwood.
Is an 18V or 36V chainsaw better?
Choose by workload rather than voltage alone. The 18V model is lighter and cheaper for pruning and modest logs. A 36V platform offers more headroom for regular firewood, storm cleanup and larger timber, but costs and weighs more.
What chainsaw bar length do I need?
Around 30cm suits pruning and small-to-medium logs. A 35cm bar is an excellent domestic all-round size. A 45cm bar is for buyers who regularly need larger capacity and can manage the extra size, weight and kickback exposure.
How long does a cordless chainsaw battery last?
There is no universal runtime. Battery capacity, timber, diameter, chain sharpness, lubrication and temperature all matter. Manufacturer cut-count claims are controlled demonstrations, not guaranteed field performance.
Do cordless chainsaws still need chain oil?
Yes. Both recommendations need bar and chain oil. They also require chain sharpening, tension checks, cleaning and bar maintenance even though there is no petrol to mix.
