    Hi, all -- have a chance to purchase a MiniBrute B2 12V chainsaw, made by Tensen in Portland, OR. Would like to hear what experiences people have had with them. We don't plan to use it for huge jobs, just clean-ups of broken limbs, keeping the fence lines (hot wires) clear of branches protruding from the 30' high Radiata Pine shelter... things like that.

    Thanks!

    Never had one, but a friend had a 12v chainsaw that I borrowed a number of years ago. It cut about 3 med. sized limbs before the fully-charged battery gave out. Is Tensen out of business? I would be worried about trying to find parts for it if they are.

    12v is a little weak for a chainsaw. Can you hook it to a truck or tractor for 12v power?

    It can be plugged into a vehicle or tractor to power it, and we've got a powerful 12V battery as well. I went and bought it (too good a deal to pass up!) anyway, even though the company is indeed out of business (and the thing is probably 25+ years old). Apparently, there are a lot of them still in use; I read a Homepower article extolling the virtues of it from a hard core off-the-gridder (which we're not, but aspire to be!), and one from another site that reviewed all kinds of various electric/12V type machinery that also spoke well of it. Going to pick it up this morning and get right to work with it... I'll report back here, shall I? :D

    Cheers

    A 12v chainsaw is nothing more than a branch and trig trimmer. 12v isnt enough power to do much more..

    Which is precisely what I want it for... most farm blocks in NZ have very tall shelter belts on the windward sides of the property (here we get the strongest winds out of the NW and the SE) for livestock to shelter and to protect things like new orchard plantings, etc. The belts are fenced from the stock, and often are hot wired to keep stock from eating them or getting through. The branches need to be kept off the hotwires, and way out in the paddocks, the only source of power is off a battery...

  7. 12 volt is all that turns huge engines over in sub-zero weather for the purpose of starting. Plenty of power. Of course, there would have to be a large and heavy motor and power to turn it. Imagine putting the starter off an Allison aircraft engine onto a chainsaw bar. Lack of power would not be the first thought that crossed your mind upon squeezing the trigger. Of course, the little chainsaw mentioned is probably not built heavily enough, but 12 volt to run a saw would be worth looking into.

    Well, spent about 90 minutes using it yesterday, before the old car battery I had it hooked up to started to die (was not fully charged when I started, so hopefully it'll go longer on a better charge). The thickest branch I got it through was about 4" in diameter, and it went through in a matter of seconds. The blade could stand to be sharpened, but overall, it's a nice little piece of machinery. It's SO quiet, I can start it without ripping off my arm, and it's much more lightweight than any other chainsaw I've used (I've got carpal tunnel in the wrists and tendonitis in the right elbow, so it was a pleasure to use it).

    Cheers
