Nearly 5 posts in a row record, lol :-)

Just nuffy playing around on McGoogle calculators and the Stihl AR3000 professional battery noticed listed appears near 32 amp hours on 36v in tradie speak

Honest 5th post winning question for any battery knowledgeable good folks out there?

We might and possibly Rossco’s work crew too in the future may all consider this whopping Lithium Stihl backpack system.

Having seen smaller Lithium batteries seriously explode from penetration before would these 32AH/36V whoppers send a bloke skyward if they slipped backwards onto a rock or stump?

Forgot to mention, @matfew (industrial sparky) has worked out a way to jump start diesel 6 pot patrols off Milwaukee batteries in a spot of bother.

Works a treat if your in middle of nsw with a dead battery hundreds of kms from any other living soul haha.


As you your last question. Lithium polymer is the explosive one. Lithium ion is much much not stable. So batteries are ion and rc cars, phones and laptops are usually polymer.

Thanks mate, appreciated!
I’m sure you meant “much much more stable” :-)

Fixed that for ya Matty !

Ion variations also work flawlessly right up against 22,000VAC daily . Tough magic that ion stuff.

Haha sorry only just got my eyes open when I wrote that.

Also meant to say most rc cars laptops and phones are usually lithium polymer hence why phones burst into flame at times.


Lithium is very reactive with oxygen. Soon as its exposed a thermal reaction occurs hence the smoke and flames.
I believe the way lithium ion is made it is much less reactive and doesn't have the danger but polymer batteries can release huge amounts of current so they both have uses.

They are freakin' expensive though, and one wonders if it's really worth while when for extra few hungiesss you can get a nice Stihl of some kind.

rmmmmm, when you live here in the Blue Mountains and surrounded by hypocritical greenies and if they are quieter running then well worth the extra $$$ can't start a petrol chainsaw here without some farkin wanker ringing up and complaining, even if its a legal cut!

Yeah, can’t imagine you’d even need to wear earmuffs with elecy saws, surely low db ?
One less thing to carry/pack on off-road adventures too.

I would say you will get about 50 cuts out of a 36V Makita with a 12" bar on dry mountain ash in the 75 - 125mm dia size range provided you don't 'lean' hard into the saw and let it do the cutting. Noise would be minimal, 25% of an angle grinder. This is usually enough for a nights burning unless you are going to sit up into the wee hours. For this reason I have 6 spare batteries, so 2 in the unit, 6 spare, and this will sort out any consequential track clearing up to say 10" dia max, probably only 6" on green timber though as its a bit stickier I recall. Still carry the 23 for the bigger stuff, but others have said, you need the fuel as well.

They're not very loud Marko..... Well, the milwaukee ones aren't. Oddly enough, our OHS code strictly forbids usage of chainsaws "including" these electric ones without muffs...

Yet, the miwaukee rattle gun range we use, which are 16x louder (than 18V chainsaws) when "rattling", doesn't require ear protection... Bureaucratic safety programming written by fresh out of uni pencil sharpeners who probably see daylight once a month....
Apologies for the sidetrack.
