This video is an excellent example of just what an informative, no-nonsense presentation looks like. All of the information a person would want to know on the subject without anything else getting in the way of its efficiency. Outstanding work, my friend.

This was one of the better reviews i have seen. I do appreciate how you showed the temperature of the batteries as they charge. Thank you for this video!

Great video. I've had the 40v 19 inch mower, string trimmer, hedge trimmer, and blower/vacuum, for the past 4 years. I have nothing but good things to say about it. I will admit that the 80v is tempting. The tools appear to be a sturdier quality and build.

I like your reviews. Thank you. I just ordered from Amazon an 18 inch 80 volt saw. I have a plug in electric saw and I really like how I can relax and think about my next cut in a quiet non hurried environment.

Good video but it doesn't really address any performance advantages/disadvantages of 80v over 40v, if there are? In the spreadsheet it looks like the 2ah/80 is comparable to the 4ah/40, at approx 145 watt hours, with the 80v being heavier and more expensive. Also cells get smaller as voltage goes up. So what's the advantage of higher voltage? What are you getting? With power tools it always seems like the 12 to 18v jump is better.

Great comparison, answered questions l hadn't thought about.
Loved the whiteboard in the background too 😊

Great review - Thanks ! Have you ever compared the 80V GW to the 60V GW ?

Good review. I don't know much about electrical, but my primary question is whether the 80V mower with the 4AH battery will "power through" my tall thick grass any better than the 40V mower with the 4AH battery. I'm in the market to buy a new cordless battery-powered mower and this is really my biggest need. Thanks!

Excellent review! Thanks for putting the thought and effort into this. The extra detail you added from your personal use was truly helpful, as was the cooling mechanisms.

Great review and video! Thank you for taking the time to make this video 👍🙏♥️

Actually the measured max voltage (at least for the Greeenworks 4AH "PRO") is 82vdc. I believe the Commercial GreenWorks 82V batteries are actually exactly the same.

In mid 2023, Greenworks introduced a 40-volt rapid charger that charges at 5 amps. They probably did that to conveniently charge their 8-amp-hour 40V battery, which they introduced at the same time.

Love the Videos you did on the 80V. You give alot off info that the MFG doesn't. Also, I believe the high amp 80V it taller. I put on some 60V videos and the 60V and 80V are amazingly similar. I'd love to see how quick you can get through a 15in pine with the 80V, I got through in 33sec with a standard chain. It would be a much better estimate of power between the 2 saws.

Nice to run into this review. I would like to know more on your experience whacking weeds with 40v and 80v trimmers. In replying to J. Wagoner you said "power and efficiency". Efficiency, certainly. I well understand the efficiency of higher voltage (less heat, smaller wires). But in actual use can you further characterize the difference in whacking thick weeds using a 40v vs an 80v trimmer.

Let me add that I just decided to buy a cordless trimmer, but wanted to see if the battery units were "ready for prime time" compared to gas powered units. I went out and bought 5 different brand/models of cordless trimmers to compare. I found that for the weeds I need to trim (coastal scrub in California, which are a bit on the gnarly side) the 40V Greenworks unit a bought did a great job, and the 80V Kobalt unit I bought also did a great job. But in using the two for 10-15 minutes I didn't notice that the 80v unit was all that much more powerful. In other words, I didn't run into any weeds that the 40V could not whack that the 80v could. That's why I'd like to hear your thoughts. :>

I have the Kobalt system, batteries are the same as Greenworks with a slight form factor but you could make it interchangeable. Kobalt 40V and 80V garden tools are made by Greenworks based in Canada. It's not just about the batteries, 40V tools are toys where 80V are commercial duty. Difference like day and night. 40V maybe OK if your demand is not heavy.

[GeoMacropulos]

I bought the Greenworks 80v snowblower in the hope that I could expand to other devices with 80v batteries. However, I don't see any other devices that use 80v batts from Greenworks.

The quality between 40V and 80V Greenworks tools is like night and day and has nothing to do with the batteries. 80V tools is more toward commercial duty whereas 40V more occasional homeowner duty. That is just Greenworks, there could engineered the other way around. Just look at the Milwaukee 10" miter saw, crazy power on an 18V battery.

4:40 This is so much more useful than amp hours, but manufacturers insist on advertising the latter only, which is actually a big disadvantage for higher voltage systems.

[ajgreen]

The 40 volt batteries being a slide system will be more future proof though, cause you can leave room for bigger batteries in the tool itself. The 80 volt batteries would have to get taller for higher capacity batteries. Which doesn’t leave much room

Very Good and Detailed Comparison and Review!! I'm gonna be putting the 40v battery to the test this Winter 🥶 since I just bought the Green works 40v Cordless Snowblower lol
