Besides the two 20 amp battery 420 vs. the one 40 amp battery of the 400, are there other differences? specifically rpms at the 2 power settings?

The batteries are quite light. Weight is not an issue with either battery. They are both 20 volts. The 4AH vs. the 2AH battery is like having a bigger gas tank, not a bigger engine.

Only owning the 400, I can not make the comparison, but the rpm and power is noticeably different between the 1 and 2 setting. You can see it rotate faster, hear the change in pitch, and see the results on particularly thick or stubborn grass/weeds/etc. Having tried this out as a possible substitution for my Poulan Pro gas trimmer, I never plan to go back to gas (keep in mind I have only a small subdivision lot (~6100sqft) with a privacy fence and multiple landscape areas). I enjoy not having to maintain, keep track of, or charge multiple batteries. The 400 is a sweet piece of equipment.

I prefer 40amp battery instead of 20 amp. It might more heavier than 20 amp but has more power to do the edge trimming job.
230913
The LST420 comes with "two 2.0 amp-hour lithium-ion batteries (model LBXR2020)." The 2 batteries that come with the LST420 appear to be about half as good as the single battery that comes with the LST400.

No these trimmers have the same rpm the only other difference I can see is the weight... The 400 is 6.3lb and the 420 is 5.7lb

No. I believe the 420 and the 400 are the same unit. Both batteries produce the same power and run speeds at 20 volts. The 4AH battery will last twice as long as the 2AH battery, but with having two 2AH batteries one can be charging while the other is in use, although time taken to fully charge is a few hours. Hope that helps.

I need more information than you are supplying to help. In short 40 amp is about 400 watts give or take. I use this controller and have had very good results, however I chose to change my legacy system to 24 volt rather than stay 12 as it provides several advantages. By reducing the number of batteries in series it allows for a better electron flow assisting in keeping the batteries balanced. My Solar array consists of 3 250 watt 30 volt black panels I got from Amazon, they are in series feeding this controller. I have 8 390AH flooded 6 volt batteries, they are configured 4 in series with two banks of 24 volts in parallel. This configuration allows for a more even charge all my batteries are now testing at full charge. When I bought this place the previous owner had 6 batteries in a 12 volt configuration and I found that only 2 to four of the 6 were getting fully charged. The batteries at the negative end were absorbing properly but the farther down the battery array the batteries never fully charged. It also increased the amperage so I have now have more available power. I also have a 850 watt wind generator tied in parallel to my solar array running to this charge controller. Since I went to this configuration I have not run out of power once, making my bride happier. I can now run my welder and other power tools life is good. If you feel you truly need to add a second controller you simply parallel the output of the controllers together. Hope this helps.

I don't know since I have not tested that. Heavy load power tolls naturally consume batteries faster. I recommend that the best Milwaukee AH batteries be used,

I have used both and the 20 v Max driver just has more power and battery's last longer no cons.

You are incorrect about the torque output of the drill with the smaller battery. The difference is in the run time, not the power.

The 944-4002 is the lighter pre-load. I'm 220 and the wife 125 and with full bags its still has enough dampner I thought the 4020HD would be to stiff. Hope this helps

Well, since I don't own both, not many people do, you should look at specs for both by weight.I can tell you the battery one has LOTS of power.I was hesitant about battery, since I do lots of sanding and never met a battery powered tool I liked.But, my wife, my grown kids, and several professionals talked me into the battery one, just like all the pros use.I am very glad, I can sand for several hours on one charge, which is enough for me for one day.The battery does one thing that is very important, it makes the tools instantly available for doing little spot jobs, you probably wouldn't bother with otherwise.I am constantly touching up around the house now with it.Go with the battery version, IMHO.

At 80mph still loud enough to listen while cruising down freeway to work. As long as it's a 12V battery you're golden. Most power sports batteries are rated around 15Ah (amp hours). Depends on the device being powered the Ah rating means if your device requires 15amps to operate, the battery will power it for approximately an hour (that is if it can discharge at such a high rate without exploding). The Boss MC400 draws a little less than 1/2 an amp (500mA). A fully charged battery will run this system 25 to 30 hours without requiring charging.

They both fit the same equipment so there is really no huge difference. Of course a 40 volt will last longer than a 36 volt. Is it significant? Probably not. So for me it would be a matter of price and availability.

It depends on how hard you run it but I get a little more out of the Lipo than the stock battery it came with. The big difference is that the Lipo delivers consistent power and doesn't trail off until it discharges.

helllo, not sure of all the differences, but I noted that 840638 charges in 3-5 hours, while 840045 charges in around 8-10 hours. That is on the product description section of each battery. Hope it helps!

fully charged I dont know, I have a half acre and it does it all with power to spare and cuts through the toughest weeds. If you give the battery a full charge you most likely wont need to buy another battery. I have been doing great with one and thats why a bought the 32 volt, it also seems to have more enitial power for the tough weeds with such a small motor. Its also so light I am not done in at the end of trimming.

They are smaller than a stock battery. But they send a bunch of stick on foam to make it fit. Mine went in a 2007 LTZ400 and it called for the smallest (120 amp) I went with the 240 and was still smaller than stock. Best thing to do is get the measurement of your stock battery and call them and ask which is closest in size to the stock battery.

Pat, I have a 4230 and it's a direct replacement. Use it everyday with out issues. My guess is all 4000 model uses same battery. The pictured item is correct one. Hope that helps.

that's what I saw also. I submitted my question to Poulan support via their email link on Jan 18th but have not received a response yet; will post here when/if I get one. I've tried to find a local hardware store that carries this model so that I could look at it but no luck. Its kind of confusing because there is also an ES350 model which is advertised as 3.5 hp. Also, on my 400E the part number on the motor housing lists it as 16" chain and bar which it isn't.

I've used both, it has more torque at the lower settings but is also heavier and gets hot faster.

With e-bikes 36 volts is better than 24 volts by far. So it stands to reason that 36 volts is way better than 20. I have the full collection of Dewalt 20 and 36 volt tools. The 36 volt tools do everything better if you need better torque, Higher RPMs or even much longer battery life and faster charging ! Keep in mind every 36 volt battery they give you is worth as much in time and power as 2 BIG 20 volt battery. Getting 2 x 36 volt batteries is as if they gave you 5 20 volt batteries. They also charge twice as fast and they allow you to drive into concrete, steel, stone much better than 20 volt systems. The circular saw at 36 volts will cut thru 4x 4 and 4x6 stock like it was butter ! The 20 volt saw is whinning and sputtering a lot. If you were going to get extra batteries with your 20 volt system, that cost alone will run your package beyond the cost of the 36 volt kit with 2 batteries. Thanks all
