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.

Why Go Battery Powered?
The 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.
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!
