The power complainers say if the grass is a bit long, or their type of grass is harder to cut, or if the grass is a little damp, as well as other similar complaints. and I still get the impression dewalt is going to cater to prosumer line with OPE they did with the 40V line and had decent results. They can mulch, bag, or rear discharge grass clippings. Using them side-by-side the difference is obvious, you can get on the Dewalt a lot harder before the overload warning light comes on and Ive never had it overheat on me while the M18 overheats rather easily. A common high-capacity cell would be 3000mah, which is 3amp hours. Agreed 100% with you, and with Jared and Jon here too. At launch it was kitted with 2x5Ah batteries in the P2 kit, later with 2x9Ah FlexVolt in the X2 kit. Sometimes you can grab a battery off a shelf or rack, and just pick the one you want, but if you have to ask someone for it, even just to hand you one you already own, what is their designation size-wise? Single-lever 8-position height adjust from 1-1/4 in.

Consider 5 people siblings that are identical in all regards, such as their strength capabilities that are split into two groups. You get the worst of all worlds- product proliferation coupled with a desire for unachievable perfection. They use 20V in determining advertised watt-hour ratings. Well use 20V Max and 60V Max as the voltage, instead of 18V and 54V nominal. By signing up you agree to receive emails from DEWALT with news, special offers, promotions and other information. Yes. Both the 2x20V MAX* and 40V MAX* Brushless Mowers feature high-efficiency brushless motors to deliver consistent cutting performance.

I can see why Dewalt want the mowers to be 20V based, but there shouldnt be a 10ah 20V battery in their range. Trip out to high heat. I did say Well use 20V Max and 60V Max as the voltage, instead of 18V and 54V nominal.. The difficult part is that Dewalt uses 20V Max in their on-battery watt-hour calculations, and so the choice was to either contradict what it says on their batteries, or to alter how I usually discuss watt-hour calculations. The secret is to read everything out loud instead of silently reading. 10.8/12v, M12, 18v and M18. And if you are invested in 20v OPE (which is this mowers primary market), the size of these batteries is a bit better on the remaining equipment like the string trimmer, pole saw, blower, chainsaw, power cleaner, and hedge trimmer than the 15 cell FlexVolts, imo. Paragraph eight, Dewalts 20V Max tools only work with their 20V Max tools. So instead of making another mower that does not really satisfy most users, make a 2 x Flexvolt running on 2 x 12 ah or the upcoming 15 ah batteries. Designed for contractor use, this mower is also an ideal choice for homeowners who already have a collection of Dewalt 20V MAX tools. That is, if you want to use 60V Max, its charge capacity is 1/3 that of the 20V Max value. 20V MAX Cordless Brushless Chainsaw, Account Change The difference in capacity between 4.1 and 4.2 is very small, depending on chemistry, so the tradeoff for longevity is a good choice IMHO. Doesnt seem any simpler to me. Mikita has done the same thing with its new system. Can This Machine Finally Hunt Down Dark Matter? I wasnt inviting that argument per se. Heck, even if the mower isnt all that powerful in terms of watts out forcing two batteries to be used divides the heat out over a larger volume. I wonder if its because Flexvolts costs more to produce or maybe its just the marketing angle? Forcing two batteries to be used could help alleviate those issues. I just wanted to note that your watt-hour calculations are a bit off. Outside of OPE, there doesnt seem to be a reason to have high-capacity large form-factor 20v batteries whereas high capacity Flexvolt batteries are used for a bunch of tools. But if they are mostly unhappy and disgruntled, they really did not achieve anything. Why wouldnt SBD want to sell high capacity 20v Max batteries at Lowes? 
I know that the larger batteries (in general) will give some tools a bit more grunt.

Notify me of follow-up comments by email. Watt h. Amph. Please refine your selection. Ignoring complicated matters such as thermal management and Li-ion max current datasheet specs, lets go back to the analogy from above, where you have 5 siblings in groups of 2 and 3. but they killed it too quickly. Never wouldve thought Id look forward to getting some slip-joint pliers, but they sure, I have 4 different small factor 4v-8v screwdrivers but using this one when I need to tighten some delicate things., I definitely dont think think calling a ball bearing pivot assisted is a good idea, it makes no sense to, If theyre using the words EDC, and are using the words assisted to refer to the ball bearing pivot, that, I dont believe I have the patience to learn to use let alone need to buy yet another variation of, Some of the other Crescent knives from the last year or two are actually really excellent for the money. I agree about the Twin Grip. Two Flexvolts would make sense. They can mulch, bag, or rear discharge grass clippings. Simple is always better. Maybe try the bigger tools first before commenting. Such a simple thing, and Im totally confused. With the tool being 20V Max, Dewalt can offer the same mower with different battery kit options, with some practical constraints based on desired performance, runtime, and retail pricing. Watt-hours is voltage x charge capacity. And, Dewalt recently launched a new FlexVolt Advantage air compressor that will be replacing their FlexVolt-exclusive model. Is Cell Count going to be understood by everyone? No all lawnmower users have a need for 60v. After all, people with ranches or 2 acres will not be looking at one of these mowers (or gas mowermore like a tractor mower). 15 HP Kawasaki Gas Hydrostatic Commercial Hydro-Walk Mower, Z254 54 in. 
At least one of the 2 major complaints would be solved. -12V Max Slimline (Original 1.5 and 2Ah models.) I dont expect it to be much larger. This is why its messier to talk about Dewalts 5Ah batteries, because those use different Li-ion cells which require a separate discussion. So, if the choice is between 2x 20V Max and 1x FlexVolt 60V Max, going the 2x 20V Max route is better as it raises the runtime ceiling. The new 15Ah DCB615 battery opens a lot of doors.
