The motor on the new dual battery mower is brushless and does provide more power in addition to more run time. Per Ego engineering department
It has the most powerful brushless motor in the entire EGO mower line (1200W BL motor is much, much more powerful than the 1000W Brushed motor on the LM2100SP). With peak power tech (drain more current from the battery), these two combines generate much more torque than any EGO mower in the market and it actually is the most powerful cordless mower in the market now.

Yes, sometimes if I'm cutting grass that I let grow for two weeks I may have to adjust the speed control down from full speed, but under all "normal" weekly mowing conditions it has plenty of power to cut at full speed. (And full speed is a very fast walk...)
I have had the self propel unit fail on it (replaced under warranty), so perhaps the LM2142SP model has a more robust self propel unit, and it does have more batteries and a stronger "brushless" blade motor, but given the cost, and the fact you have a small lawn, I'd recommend saving the money and getting the LM2102SP.

So if your a person who don't like cleaning up after you get through cutting lawn then get the model LM2142SP but if your a person who likes taking care your lawn mower after cutting the yard then the model LM2102SP will do fine for you.

"The Ego PeakPower technology combines the power of 2 EGO batteries for longer run time AND efficient power draw. The motor on the new dual battery mower is brushless and does provide more power in addition to more run time. Per Ego engineering department"
It states AND efficient power draw which states it is more efficient, not necessarily more powerful. the second part is just stating that the new brushless motor is more powerful, which I understand is true over the prior motor rating of the non brushless motor and not necessarily running "more powerful" due to the dual batteries.
If it doubled the current then run times would not be longer per se. Details and specs on this issue would surely help in making a decision based on facts.

I think no matter what I say, your trying to convince yourself that the single battery motor has the same torque and power. Believe me it doesn't, I have both and can compare the two. It is a big difference. I sent you the youtube video on this lawn mower. If you don't believe me or the youtube video there is probably nothing anybody can tell you to convince you. I guess what I am telling you are not facts!!!!. It looks like I am the only owner on this site that has this two battery lawn mower. That's too bad. At least Ego can get rid of their stock of single battery lawn mowers. On Sunday I mowed our lawn (860sq. feet). I have thick Kentucky blue grass and cut it at 31/2 inches. Our lawn has may different grades. I now can run our lawn mower at a higher speed and it never over heats. I finished in less that an hour and charged the batteries on two different rapid chargers. Both batteries charged in 15 minutes which shows me that they are both being used at the same time (more efficient draw of current). I use two 7.5ah batteries which is probably an overkill. Do you really think that Ego is going to tell you that the dual battery lawn mower is a lot better that the one you bought. I don't think so. I have a 2018 M550 BMW which is a v8 with twin turbo chargers. The BMW 540i has a single turbo. Due you think they have the same power and torque.

One is not necessarily better than the other, it’s more important that it fits your need. I personally would like to know if there is a substantial “power” difference per specs between the same motors but dual vs single battery and then I the consumer, can make a decision.
Sorry if it affended you, that was not my intent. I think EGO has the best product out there from what I have read but I’m just trying to understand what I am buying and what fits my need the best.

An electric motor is obviously not the same as a gasoline motor in terms of torque and horsepower. The advantage of the dual battery is that they don't have the same power draw as a single battery and therefore you get longer running times, more torque and less likely to overheat. The engine is less likely to overheat because the extra current the two batteries are sending to the motor. I don't know if that explains it. All I can say it is like night and day between my single battery and dual battery. It is just more efficient. I guess it is like comparing a 12 gauge extension cord with a 14 gauge extension cord. My motor in my 30 gallon air compressor could burn up if the use a14 gauge extension cord because it limits the amperage to the electric motor. Another example is most electric cars that are sold have optional larger batteries if you want longer running times. As the battery runs down on these cars their 0 to 60mph time get slower, which means they are losing power and torque. If you did purchase the dual battery lawn mower you will be a happy mower.

With the single battery mower, did you ever have cut grass left behind where it was visible and not mulched enough to fall into the grass and out of sight.
If so, did the dual battery mower alleviate this issue?

You can't see many of the items in person as the Home Depot display is usually pretty small, and EGO (a lot of electric tools) do not have a standard in the industry that would translate in to HP, torque, etc.

I was just saying a picture is worth a thousand words and it would be cool to see a side by side. As you are the only guy I know with both mowers, I suggested it to you. If that kind of thing doesn't interest you and you don't find it to be fun, then no worries - you don't owe me anything - I was just throwing it out there.

IF the dual battery mower has more torque and power when needed, it would be a better buy for my use, however if it does not, I like the other benefits of the steel deck with the side discharge and shorter nose. One is not better for everyone, I'm just a guy trying to spend my $$ for what I feel is the best use for my lawn and when the MFG can't answer my questions, it makes question if we are stumbling over marketing terms.
If EGO won't put out the information, hopefully someone will do a video on one some day as I am sure many people are interested. Enjoy your mower.

This is an expensive unit, due mostly to the cost of the two batteries if you buy the kit. But if you are wanting a nice, powerful and quiet lawn mower to tackle larger lawns, look no further, this is it.
What is PeakPower Technology?
This new mower is the second tool from EGO that will run on a single battery or also capable of running off two batteries. EGO calls this technology PeakPower and it is software that is capable of detecting the size of the batteries in the tool. Obviously, the larger the battery, or batteries, the better it will perform. The software will look at the number of cells (battery pack size) that is can pull power from and adjust the amps drawn from the battery, or batteries for optimal performance. This gives the user options if a battery was forgotten to be charged or if one were to possibly go bad. We found that there is little difference between running the unit with a 7.5Ah single battery or two 5.0Ah batteries, but all of our testing was done with the two 5.0Ah batteries that came in the kit.

or
Does it not need the high RPM mode and the increased power lets it do more at its standard mode.
Both of the above mostly in regards to thicker patches of grass and clippings left behind.
Bill has posted some very positive reviews, but a second opinion is always a plus.

As far as the torque goes, I can confidently answer that without using the mower. The dual battery mower has 200 more watts than the metal deck. That fundamentally means it will be more powerful and with more torque if you do the math given watts and RPMs, the metal deck has about 2.34lbs ft torque vs the dual batteries 3 lb ft of torque.
I know there has been discussion on here about "peak power" technology and the like but I think its silly to buy into any companies marketing jargon. There was a class action law suit against the gas mower companies for this very thing. It's only a matter of time before electric tools are held to a universal standard. Saying that the mowers are as powerful as gas is really misleading unless you are comparing it to a weed wacker, otherwise, that claim is patently false 99% of the time.
Lithium Ion batteries typical maintain their power band as opposed to nickel metal hydride. I won't say that's in every instance because I don't confirm anything without hooking it up to testing equipment. That said, I would guess that the dual battery aspect is only important in that it combined the amp hours of two batteries and the built in processor can draw from them in an efficient manner. That doesn't mean that two batteries make it more powerful unless you want to argue that at the very end of a charge a single battery mower will lose a percentage of power before it goes dead. I don't think that is very relevant. Instead, I would focus on the fact that the dual mower has a higher wattage (20%) and therefore is going to be 20% more powerful if you look at the torque figures that theory is pretty much confirmed.
In the end it all depends on if a particular tool works for a particular person. There are people who say the base model mower is the greatest thing ever and some say it sucks so all you can do it make an educated guess. I am going to test this thing out this weekend on grass I have intentionally left uncut for almost two weeks so I will put it through its paces. However, even if there are no issues it won't change what has already been discussed 100 times. Electric mowers are great because there is no maintenance, quieter, lighter, etc. But they aren't as powerful (despite the promo language, in fact about half the torque of my midlevel gas mower), cost twice as much and they take forever to repair (unless you can do it yourself). Meanwhile, any idiot can keep a gas mower going for decades.

I too found that I upset all of the EGO fans on this site when I criticized EGOs lack of disclosure in specs between their models at the time as I was trying to make a decision between electric mowers and mowers within the ego line.
Overall, I really like the mower, but it is not as powerful as a gas mower. The bonus is that my wife and kids can easily use the unit and they all comment that they love how light it is vs the gas mower. The other pluses include storage in a small footprint, no gas, ease of use, plastic deck underneath stays very clean, etc.
I have had to cut my grass in the spring a couple of times in a row when I have let it grow too tall due to constant rain which prohibited a weekly cut. I usually cut in pre growth spring at a level 2 prior to putting down fertilizer and then level3 for spring and sometimes level4 when it gets really hot out as I do not have an irrigation system. I have had a time where I had to cut it at a 4 and then a 3 since the mower would overheat and shut off with a red light. This has only happened once or twice due to weather and fertilizing periods of the year. The majority of the year, a weekly cut and it does just fine. In all honesty, the gas mower would if cut in these times, BUT it also would of left a lot of clumps if grass due to the amount being cut off.
I do hand sharpen the blade every third cut or so as I feel the light weight blade does not hold an edge like a heavy gas mower blade. Not a big deal as it is really easy to take off and sharpen by hand, but it is not indestructible like a gas mower blade.
Overall I like the mower.

I bought the high lift blade as well. I believe it’s heavier so maybe if I sharpen the crap out of it, the combo of the bigger motor and blade will carry through the tall grass that you were getting caught up on. Like I said, I have very tall grass right now so we will find out!

Slaw the high speed change for thicker grass is a one step - noticeable sound difference - back to normal speed when no longer needed system. At least on the single battery mowers.
The peak power technology was explained by an Ego engineer (not marketing department) as able to drain more current from the batteries and thus provide power/torque.
The high lift blade is intended for bagging, although some have said they got better mulching results. But, mulching is not what it was designed for.

Usually a battery has to have a current rating higher than that of the motor otherwise it can explode. It would be interesting to deconstruct both brushless motors to see if there is a spec plate on them that says what the wattage is. I wonder if both motors are rated for 1200 watts but they can only claim 1000 on the metal deck due to the current limitations. (Oregon Mike, we know that could void the warranty, haha)

EGO’s Representative sent this statement out in 2018.
Hello EGO Community! We’d like to take this opportunity
to clear the air regarding our new Dual Battery Mower. Since there has been a
great deal of interest and a bit of confusion surrounding this mower, let’s
jump into the facts straightaway.
-This mower’s motor is brushless.
-This mower is rated at 1200W.
-This mower’s PeakPowerTM technology delivers more torque, longer run times,
and a more efficient power draw.
-This is the most powerful brushless
motor in the entire EGO Power+ mower lineup.
You’ll want to note that all of these statements have been confirmed by our
engineering team. Also, the Steel Deck
Self-Propelled Mower is rated at 1000W. Our apologies for any
misunderstanding.

Battery 21" Mower on Amazon: https://amzn.to/2OKT8VM New Dual Battery
Mower - This NEW Dual Battery EGO 21" Self-Propelled mower provides longer
run time not only because it has multiple batteries! This the EGO's first
BRUSHLESS lawn mower. You will not see the word brushless on this
lawnmower but rest assured it is. This lawn mower operated very
similar to the dual battery snow blower with what EGO calls PeakPower
technology. Basically, the PeakPower technology can determine what
battery or batteries (It can run off a single battery) you have in the lawn
mower and the software determines the most efficient power draw. This
allows users to use multiple batteries for long runtimes and more torque or the
ability to run one battery while the other charges. While this new model
looks and feels almost exactly like the single battery 21" lawn mower, the
difference lies in the motor and the torque it can provide. With two
5.0Ah batteries, one can see upwards of 40% more torque from this unit.
that allows you to run some of the upgrades we list below with little effect on
runtime! This is an expensive unit, due mostly to the cost of the two batteries
if you buy the kit. But if you are wanting a nice, powerful and quiet
lawn mower to tackle larger lawns, look no further, this is it. What
is PeakPower Technology? This new mower is the second tool from EGO that
will run on a single battery or also capable of running off two batteries.
EGO calls this technology PeakPower and it is software that is capable of
detecting the size of the batteries in the tool. Obviously, the larger
the battery, or batteries, the better it will perform. The software will
look at the number of cells (battery pack size) that is can pull power from and
adjust the amps drawn from the battery, or batteries for optimal
performance. This gives the user options if a battery was forgotten to be
charged or if one were to possibly go bad. We found that there is little
difference between running the unit with a 7.5Ah single battery or two 5.0Ah
batteries, but all of our testing was done with the two 5.0Ah batteries that
came in the kit. LM2142SP Features 21 self-propelled mower Features PeakPower

largest benefits of a battery operated lawn mower are the lack of pull
starting, lack of buying gas, lack of changing oil and a significant decrease
in noise. While testing out battery operated lawn mowers, Jeff and I are
able to have conversations without yelling. Try that with any gas-powered
lawn mower and you will be screaming at each other and most of the time not
understanding all that is said. The largest downside to a battery-powered
unit is, or was runtime. Prior to this model, the average runtime we
would see with the single battery EGO was around 45-minutes. With this
new unit, one will easily see 75-minutes while mowing a normal lawn. Many
people start to look at a small tractor at the point where they are mowing a
lawn for over an hour and a half. This small battery operated unit opens the
door for commercial contractors to use this unit for trimming. The
runtime will easily allow for its use on and off while trimming for a normal
workday. Upgrades We have found that is very thin stranded grass that is cut at
more than 3" that there can be strands of grass left uncut.
This is because the blades on most battery-powered lawn mowers are designed for
runtime, not lift. There is a high lift blade available from EGO that
will lift the grass and cut better, but it will slightly reduce the runtime of
the machine. This new machine will have this blade much better and still
give a long runtime. We highly suggest you try this blade with the new
mower! EGO Power+ AB2101 21" Lawn Mower High Lift Blade for

I'm not sure what your point is. Are you saying that this topic has already been broached? If that is the case you are not breaking new ground by suggesting a topic on this forum has been covered ad nauseam. However, the point of a tool forum is to talk about and review tools, people find that enjoyable for some reason.
The guy in the video you embedded is mowing down field grass with ease yet Ken said the same mower would overheat on tall turf grass (much shorter grass for the layperson). I would be more inclined to give Ken's review more weight given that Youtube channels have been known to receive funding from sponsors to talk up their products (and the channel you referenced, reviewed snowblowers by their ability to displace snow on a hockey rink, if you have a hockey rink for a driveway, disregard).
That is why it is important to get several (and in this forum several hundred) opinions on something. If I misconstrued your point, my apologies but then please elaborate....

This is my second year of ownership of the Ego dual battery self-propelled lawn mower. I have Kentucky blue grass sod with a sprinkler system. I mulch it at 21/2 inches early spring and late fall. During the late spring, summertime, and early fall I mulch it at 31/2 inches. My lawn is very thick and always looks great. Not once did any lights turn on since I had this lawn mower. I use two 7.5 ah batteries. I have talked about this lawn mower numerous times in the past. This is a great lawn mower. I have criticized the Ego snow blower in the past because of its limitations and received a lot of heat for it. If I thought this lawn mower was junk, I wouldn't hesitate to say it. I am pretty sure I was probably the first person on this site that bought this lawn mower. So I have reviewed this tool in the past. I gave that recent information out for people who were interested in buying it. Now people can compare my review with Ken's. By the way, I don't receive any funds from sponsors.

My lawn is thick this year and looks great and healthy overall. I can imagine there are some lawns and types of grasses (not to mention mowing habits) that an electric mower will fail vs a gas mower in certain scenarios, but for my lawn I am sold on electric. The small “issues” (hand sharpening blade more frequently to keep a sharp cut, and having to cut a little higher on real long grass; which should do anyway) are both out weighed by all of the pluses if the electric mower.
In the end my lawn looks great which is what I am after.

My first thought was that I didn’t properly fasten the full battery into the mower and so it wasn’t being used. That seems very unlikely as it’s pretty obvious if the battery is not installed correctly. Anyone else with this model experience this? Ken?

Is there a big different in performance between the LM2142SP (2 batteries) and the LM2102SP (1 battery) mower? The reason why I ask is because I had to special order the LM2142SP (it's defective out the box with a constant orange flashing light) and it took about 2 weeks for me to receive it. HD has the LM2102SP in stock. Any feedback would be appreciated.

Here are some initial thoughts:
-First thing I did was swap the blade that came with it to the High Lift. The blade that came with it was SUPER sharp though, I was impressed by that.
-The mower constantly revs up/down/up/down/up/down. Must be a battery conservation thing????
-The self-propelled is different. It's improved.
-The cut, unfortunately, seemed to be exactly identical to the 2102 thus far. The infamous "trail" of grass was there just like before. See pics below. I mulched and didn't take much off.
https://i.imgur.com/WWduhUw.jpg
https://i.imgur.com/lvrLw1H.jpg
-I used (2) 7.5 batteries that I already owned for the 15-20 minutes. I put both on the charger after I was done and the charger indicated that both were full. All lights lit up green and it wouldn't turn on. This makes me think that it was pulling from both batteries but I can't confirm that with 100% certainty yet...

Al,
I have the same lawn mower (two 7.5ah batteries) and mulch my grass (Kentucky blue grass sod) at 31/2 inches and it looks great. The higher you cut it, the longer the roots. The stock blade mulches better than the high lift blade. I bought this lawn mower when it was first available. Looking at your posts you'll probably be happier with your Toros and Hondas. I would return it.

Al,
When you receive you new one. try mulching the grass at 31/2 inches and use the standard blade. Believe me, the high lift blade only worked better when bagging. Try cutting the grass, if you can, when it's dry..Good luck and I hope you have better luck with your new lawn mower when you receive it.

After mowing for roughly an hour, I checked the batteries in the mower. Both were showing 2 bars. So mine is definitely pulling juice from both of the batteries, not one at a time.
I think the self-propelled, at the fastest setting, is slower on the 2142 compared to the 2102. Still plenty fast though...
