    the 40v 2AH battery and 80v 2AH battery both take an hour to charge.. those charge faster than the 40v 4AH battery because they are only half the capacity.. nothing to do with volts

        Nice technical video, well explained. As I cannot get information anywhere else I thought I would ask, is there a torque difference in mowers when you use a 80v vs the 40V, Which one has the more power to tough it through thick grass, and also chop up leaves, vacuum leaves?

        • createthiscom

          @Kue Man oh that sounds good. yeah, the original twin force greenworks 40v was pretty bad. it wasn't even brushless. maybe they perfected it.

            @createthis I have the newest 40V Kobalt mower (manual push) and it has one blade. Been impressed so far. I think it is relabeled by Greenworks for Kobalt. Super solid deck, wheels, etc. Not so plastic like the Ryobi or earlier versions of the 40V Kobalts.

              My 40v mower uses two small blades. My 80v mower uses one large blade. So yeah, there’s obviously a torque differences in the motors, but they’ve designed the lower torque system to do roughly the same work. The 80v is always going to be stronger though. For me it’s more about runtime and cut quality. The 80v mower with the 4ah battery goes a lot longer between battery swaps. And the 40v mower tended to leave a run of uncut grass between the two blades so you had to go over everything twice. I strongly recommend the 80v mower.

                I just got a GreenWorks self-propel mower I think 21in I have 1 40volt gmax 4amp lithium ion batter I’m only getting 30mins roughly of mowing time my yard is lot bigger and need 1.25 more charges to finish would it be worth getting the 5amp for my secondary battery so I can get done hopefully all at once or is it not run much longer then the 4amp and save lil money n just get another 4amp I think price now is around 120 bucks where the 5amp is 180 any advise be helpful

                  So my 4 times using my 21in deck self propelled mower 40volt with a 40volt 4apm battery got 30mins first time use 2 time 25 3rd time 16 mins and this last time around only 6mins all on full charge and when I push the light on the battery see what’s left nothing so it’s drained wouldn’t recommend the 40volt mowers from GreenWorks battery is just not cutting it taking me ages to mow my yard with having to always recharge and getting shorter run times each time

                    Sorry, I’m not sure. I don’t have the 5 amp hour. I know there was a huge run time boost from the 2 amp hour to the 4 amp hour. I wouldn’t expect the 5 to be that dramatic of a difference compared to a 4 amp hour though.

                              Lowe's are selling a 60v products now. Wonder if that's a good compromise over the 80v.

                                I'd stay away from GreenWorks tool altogether...unless you want all your batteries to die less than a year. I have over 8 of them...ALL DEAD!!! waste of $$$ 80v, 40v, & 24v.

                                  No. For the same power, the higher the voltage, the lower the current; and the lower the current, the lower the overall losses and the better the whole system efficiency. So, increase the voltage is always a better option. @creathis : Talking about efficiency, and without any polemics, it seems quite silly to start from gasoline, pass through a generator, converting to a sinusoidal voltage to supply the AC to DC converter (its own charger) to eventually charging the battery. It would be justified only in case of emergency, I mean, if there would be no available utility plug.....

                                    Hello Jesse. Say, I have multiple Kobalt 80v tools which are actually made by Greenworks, one of which came with a silent charger, no cooling fan. Battery gets really warm while charging. This is odd to me. All of my other chargers came with cooling fans and charge with 4 amps. The silent no fan one says 2amps on the bottom label. Which charger will preserve the longevity of the battery packs better? 2 amps and no fan? Or 4 amps with active cooling? Thank you. David

                                              • Twinkle Twinkle NaNa Star

                                                You will have the same performance. It's wierd how all this power tools rate the voltage. These are lithium ion batteries and they use 20 batteries in series with a nominal power of 72v and a maximum power of 82v. I'm not sure why they don't use the nominal power instead. these batteries have the same characteristics of a 72v rated ebike battery

                                                  How do you charge with solar? Through an inverter or is there a dc to dc means?

                                                    For greenworks I think they only offer AC chargers, so always through an inverter.

                                                        Please advice! I can not make decision. Here is only 40V and 60V available. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I guess a gas mower only my chance.

                                                              So, are you saying that the 40v tools are compatible with the 40v batteries? I'm confused.

Debating (with myself) on buying the Greenworks snowblower. Do the 40v and 80v models have the same size motors? Will the 80v just run longer or is it also turning the motor at a higher rpm rate? What's the deal? Thanks.

Looks like the 80v package doesn't give me much more for the money (assuming they perform the same which I actually have no idea about) other than less weight or am I missing something?

So yes, usually that will translate into more power, greater run times, etc, but a lot of that comes down to the engineering in the rest of the system. If a 40v system and an 80v system perform the same, usually the 40v system will be heavier. Hope that helps.

That is also a variable speed mower, which means it doesn't always run at 60V, and will down the voltage depending on the grass height and grass type, and you'll be able to hear when it goes into "high power" mode for tough spots. 40V is not powerful enough IMO, and 60V would be the way to go, but personally I went with the 21" 80V version. The batteries are rapid charge, so you don't need as many as you think. If you mow the front with a small battery for example, you can take a 15 min break to get some water, and by the time you're done the battery will probably be topped off in the rapid charger anyway. Its not like the old lead-acid mowers where they trickle charge. I also save money by using the same 2AH 80V battery in all my devices (trimmer, blower, hedger), as the battery is far more expensive than the tools usually.

                                                                                  @DumbDuck44 Ok, I did not know they not advertise Wh before. So 40V 6Ah should be the same run time as 60V 6Ah but more powerful when mowing high grass, right? I can not make decision. Here is only 40V and 60V both available with 2, 4 and 6Ah batteries. I am still very skeptical about battery life in self-prop mouwer as (greenworkstools.eu/cz/en/products/lawn-mowers-gd60lm46hp ) They claim about 80minuts with 4Ah, but there are videos when it run with 5Ah up 20minutes not even high grass.. I have about 1500m2 its like 1/3 acre.. 50% is steepe. I count on to buy at least 3 x 40V 6ah (in total 648wh) or 2 x 60V 6ah what is the same 648wh in total. And now the price for the wh is almost the same here. I guess I do more squer feet with 60V

This makes high voltage systems seem like they have a smaller battery because its less amp hours, when in reality its the same. A 2AH battery for a 80V system is the same size as a 8AH battery for a 20V system. Both batteries have the same capacity of 160 watt hours of work its able to do.

                                                                                        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. :> Finally, for reasons other than pure whacking power, I fell in love with the 80v Kobalt trimmer. It just was the all round best of the five. As best as I can tell the 80v Kobalt unit is nearly identical to the 80v Greenworks unit, and in fact it is claimed that the Kobalt is just a re-branded Greenworks made for specifically for Lowes. If true, the biggest difference between the two right now may be PRICE. The latest model 80v Greenworks trimmer -attachment capable- on Amazon is a whopping $348 with 2AH battery (www.amazon.com/dp/B00YBFXCMI?ref=emc_p_m_9_b). The 80v Kobalt trimmer at Lowes with the same battery is only $199 (www.lowes.com/pd/Kobalt-80-volt-16-in-Straight-Brushless-Attachment-Compatible-Cordless-String-Trimmer-Battery-Included/50394980.) WOW!!!

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!

                                                                                              I bought the 40 V 2Ah version with 2 batteries supplied as the 80V lawner seemed too heavy to move around trees in out of the garage, etc. The 40V has lots more power than previous 10 year old Bosch 36V Rotak. Went through my 'meadow' style lawn with lots of clover with ease. So I'm happy, the 40 volt more than meets my needs in terms of power. I also prefer that size in case I buy the hedge cutter and lawn trimmer with the 40 v. Those tools with the 80V wer very big and looked like tools for the strongest man competition. But I've only got about 400 square meters so much smaller than backyards I see in the US videos here. Having said that the 80V charging system with ventilator seems higher quality that should mean longer battery life.

It's probably been said and I've missed it, but is there an actual power difference between the 40v and 80v systems? My guess would be that if there is it's related to the tool itself, not the battery. We use a couple different Makita 18v impact drivers at work and one model definitely has more power than the other, both using the same battery. I'm leaning toward the 80v simply because I'm guessing it's a little better tool (battery notwithstanding).

Also, for the same work load (Watts), the battery contacts current on the higher voltage packs is less than the lower voltage packs.... Watts = Volts x Amps. This means the battery and tool contacts will last longer... experience speaking :-) Running a gas generator to charge an electric mower...? seems to defeat one of the big purposes of having battery powered mowers... but that's my opinion.

Your temperature while charging pics caught my attention, as I just finished reading a review on Amazon from a guy who's workshop caught on fire when he left his Greenworks battery charging overnight. I think I'm going to try and rig a cooling fan to the charger. Have you looked into this?

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.

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.

Haven’t had any problems yet using it once or twice a week during rain seasons. I’m getting tempted to buy the 80v lawn mower as well but I already invested in an extra 40v spare battery ($90 on amazon) besides the ones that came with the mower. Patience my friend!!!

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.

Mainly it's a quest for convenience and time savers. Greenworks looks to be a decent option. we shall see.

I ended up calling the manufacturer after waiting weeks for two different emails that were not responded too with various questions I had. I did end up buying into their 80v system with some great deals on amazon and elsewhere on the internet. I actually sold 3 Sthl gas tools and was able to build my entire 80v tool system with money to spare. I was a bit frustrated with the lack of information on there website and also when calling them they could hardly answer any of my questions - that was kind of odd. Customer service is pretty poor so far in my experience. I did however get the weights of batteries, at least this is what the green works representative told me: 2.0 Ah - 3.19lbs 2.5 Ah - 3.19lbs, 4 Ah - 4.2lbs, 5 Ah - 5lbs. I just think its ridiculous they don't have a chart of average runtimes with the different batteries in the different tools. Surely they have this information somewhere as they tested all the tools thoroughly before releasing them on the market. There awesome tools and they shouldn't be shy about sharing that information. I run a professional Masonry & Landscaping company so I was trying to figure out how to best build my tool line with them. I did read somewhere the 5.0 Ah battery shouldn't be used in the chainsaw for a safety weight balance issue. I think that is the only tool it can't be used in though or is NOT recommended to be used in.

Thanks for the feedback. I was hoping to buy a hedge trimmer with the included battery because I regret not getting an additional battery with one of my prior purchases. Now I have to wait between mowing and weed wacking for a charge.

Are the actual run times longer or is it more about having extra power and quicker charge time?

Lower voltage/higher Ah battery will need higher peak and avg. current to charge, causing higher heat emission from (basically) the same cells. This will lead to shorter cell life.

                                                                                                                                                                  Jack, the battery energy capacity actually should be measured in Watt hours. Higher voltage (with the same power) is better for higher efficiency and less heat while working/charging. It also should be noted that in US most sompanies use "mmarketing voltage" while in EU it is nominal numbers that are just multiplied nominal cell voltage (3,6V). So the real world lithium batteries are mostly 18/36/72V.

Higher voltage means the wires can be thinner while delivering more power. Basically, lighter and more efficient, but possibly more dangerous too.
