Lithium powered saws?

I have noticed with the battery powered saw the blade needs to stay sharp. I don't know if they're all this way, but if it gets a little dull the motor will shut off as if there was a kickback. I took out most of the crown with my DeWalt until I got to the stem and used gas power.

I'm just curious what the power is like in comparison. I've had a 020 or a 200 or a 201 hanging from my belt for so long I don't even notice the weight, and I am very impatient when it comes to cutting, lol. When I wont be cutting anything over 2 or 3 inches, I just leave the power saw on the ground and use my hand saw. To me, a middle ground is useless. I see the possible good points of the electric, but if it isn't close in power, I wouldn't get one.

Depends what your cutting. I love the 201 but it is now more of a special occasion saw. By the time you pull start itthe limb has been cut by a battery saw and I'm on to the next one. Unless your one of those guys that just keeps the saw running.

I've been hearing that car voltages were going to go to 24 or 40v for the last 20 years too. I was also told that the metric system was the future of measurement when I was a wee lad in grade school 35 years ago.

I doubt we'll be wearing belts as a primary means of tool power. There may be a few systems available though.

the metric system is the past, present and future of measurement if you are measuring anything of importance.

tell me why you believe tesla uses "better" motors than other brushless devices. I would be surprised if he made anything at all. I believe he's a parts bin guy with big ideas. Brushless motors are pretty advanced. Have you seen what is available to the RC world? Hobby cars have some awesome brushless stuff.

Tesla's high end cars use a 4 pole 3 phase A/C induction motor, not single phase DC motor. The cheaper model 3 uses permanent magnet motor but it is also of a 3 phase (AC) design.

Look at the advances in RC helicopters with the introduction of brushless motors and lithium batteries. It's an incredible move forward from liquid fuel. It's coming, just a matter of time.

A friend of mine races an 840 cubic inch Outlaw 10.5 drag car. On these cars they spend thousands of dollar on a set of titanium wheel nuts to shed a 1/2 pound. The rules require that they be self starting (funny cars and dragsters use remote starters) so about 5 years ago he hooked up with a company that does R/C racing work and had them build him a run battery and a remote starter pack that the crewman could temporarily hook to the car while starting then disconnect once it was running. It was small enough to fit in a pocket after starting, but spun the 840 inch 14 to 1 compression motor no problem.

I still don't understand why you think Tesla is unique in the respect to electric motor technology.

Example; this $89 skateboard motor has 14 poles

The post of mine (which I assume you were replying to?) stated that Tesla's motor's are not run on DC voltage which as far as I know all chain saws are. Instead they take DC power and convert it to AC power for the electric motor. The number of poles in an AC motor is not a more is better deal, it is simply an engineering choice made based on HZ vs desire RPM and a slippage factor.

Tesla's cars are recognized for high power and range ....which seems to be what is lacking in the opinion of most, in the current batch of electric chainsaws.

Do I think they are privy to some proprietary electric motor? No I just feel they do what they do very well and that if they wanted to they could probably engineer a very good chainsaw.

Elon Musk is like most modern day highly successful CEO's of major companies. He is a great promoter and finds and employs people with great talent. If you resent him for getting deep in bed with the US gov, I can respect that.

@TallTreeClimber do you have a top of the line gas top handle to compare your Makita to? I am interested in the electric saws, but I bought 2 stihl 201tc's in the last 8 months, so unless one explodes, my top handle budget is spent for now, lol.

Get one of the battery saws, then you can sell me one of the 201TCs!
Or I'll trade you my 192T or 193T.
 
I don't use them but I just discovered on the 20v DeWalt saw, it will also use their 60 volt Flex batteries.

So where can I find a narrow kerf, 3/8 pitch .043 gauge 45 link chain? Would the .05 Gage work I wonder?

So answering my own question I tried the .05 gauge low profile chain on the DeWalt and it worked great, it still is not narrow kerf. Oh and that bit of wobbling with the bar that was reported on one of those product reviews oh, that doesn't happen on mine.
 
Personally, I find the SEC statement, the agency's contempt motion response shows that they are "playing for keeps" and will "crush Musk if needed". troubling. No doubt Musk should have kept his comments to himself, but his innovation in at least 3 separate fields of endeavor have benefited me.
 
Point taken. Never the less, The SEC's sanction of Musk's free speech, with regard to his criticism of their action is overreaching.
