Let's Go All In On Battery Tools . . . Or?

Battery saws are the best thing to happen to modern tree work since SRT, to refuse to use them is just sticking your head in the sand.

No system is perfect, but I grab my battery tools over gas tools every chance I get.
 
I didn't say that they have no place in tree work, just that they're not good enough for me to justify buying them YET. They have some distinct advantages that I wish I could have on my saws, like pushing a button gently with my thumb, and knowing that the thing is on. I wish my saw was so quiet. I wish that my saw didn't have hot start issues, or require warming up. I LOVE the idea of a battery saw, but they cost twice as much and don't deliver the power for the weight. Not yet at least. I understand that someone has to foot the bill for the ongoing R&D, but the eagerness of these companies to be the first one on the market with the next slight improvement just clogs the world up with mediocre garbage. My one friend who has been rockin Husqvarna battery saws since they came out saw me running my 2511 in 12" Ash, decided that he was gonna get two of them, because they're actually lighter and have more power than his T540i. I still prefer those Husqys for medium sized pruning jobs when I work with him, but frankly, I would rather keep a sharp silky on me than lug that thing around to make the occasional cut over 2". With him, we focus on a higher number of small cuts, and I climb around on small wood a lot. All's I'm sayin' is for my money, I'll wait til the tech improves and let ya'll foot the bill for the R&D necessary to get us there.

My first foray into electric polesaws and a battery top handle proved really useful for a removal for a couple where the lady that had cancer and was undergoing chemo. Her husband gave her meds before he left for work in the morning and she would go back to sleep till noon or 1:00 PM - afterwards they thanked me for being quiet in the front yard. But I echo all the comments you made above. They are to me just one ore tool in the toolbox.
This guy does lots of Li battery "fire" stuff in his YouTube channel.

I look forward to having an all electric tree care service, specifically to be the quiet tree guy. I want it to get there for sure. I hate the loud ass saws. If money wasn't an issue for me right now, I would just buy two of everything thats available, just to be able to offer that service. For a price, of course.

What fire extinguisher is that? Can we get them? Anyone know?

It's a pressurized nozzle designed to shoot water straight up into a car battery system to cool it from the inside-out. Normal methods of extinguishing fires like foams and powders which smother flames won't work because the problem is the buildup of heat. Trying to cool it from the outside ironically prolongs the thermal runaway and can keep an electric car burning all night, where without intervention at all it would completely burn out in an hour.
These are specialized firefighting equipment, I don't think they're commercially available.
 
Ha, wonder how many of those extinguishing units are one time use as the car tires burn and the car's weight squats onto the unit pinning it?

Great info, thanks Bob's yer...
 
The RC and diy ebike guys went through all this when the original more volatile chemistry was used before the Fe formulation. Somewhere there was a video of a guy testing fire protection of sand pile, ammo case, ammo case sand pile, wood stove surround type measures, regular drywall etc all done with raw no protection IC packs purposely overcharged. IIR the result was only partial success. Probably 18650 packs. Another twit pounded a nail through a cell to watch it go poof. I've shied away from home brew LiIon packs because of the need for mechanical drop protection, charge/load overload protection coupled with thermal under/over shutdown. Not to mention charge control.

Not too many stories about drills burning up. Rigorous QA.

On one airliner (original chemistry) they built a fire containment box with a fume vent to outside.

Low cost scooters, bikes and hoverboards be wary IMO.
