Battery powered chainsaw

[Fuddyduddy1952]

lol... an $80,000 solution to a $800 problem! Cheaper to just fill the glove box on your old F150 with spare pre-charged chainsaw batteries.

And Fuddy, when I mentioned DC-DC converters for charging, I was referring to a manufacturer-engineered smart charger based on DC-DC converter tech. Not just home-spinning your own.

Greenworks makes a DC-DC smart charger? I had no idea...tell me more!

What a way to shortchange the saw manufacturing industry. Truth is they absolutely can pressure their battery suppliers for better battery technology.

Of course. Every supplier knows if something better comes along then they are out. Whining about it isn’t going to make things advance faster.

You can charge a battery from a running vehicle. That’s no problem at all. The debate was charging a battery from a not running vehicle.

I have a Makita charger for the service van and also an inverter for 120v power.

Quicky learned I needed to install a second car battery with charging from alternator to have a reliable system and not drain the truck battery to the point of not being able to start the truck.

Yes. You need an inverter, but according to Greenworks 80v charger+500W inverter, 30 minute charge really drains battery.
I have an inverter & chargers and need to cut up a large oak in a few days which I can test with my truck.

My Makita 120v charger will not work on my Statpower 1800 Watt inverter...

My guess is modified sine wave not clean enough?

That's an expensive inverter...strange it doesn't work! Wonder how/if it works with other chargers?

So many debbie downers.

Why even be in the battery thread if you just going to talk down.

Every tool has it's place and man can not own enough of the right tools for the job at hand.

Wife saved me alot of work with that right there battery cutting the limbs up for smoker wood. I tried it with gas saw. Was just easier her way.

I hired a guy to help cut up a black walnut storm damaged tree. He had a sawzall with your pictured Diablo 9" pruning blade.

That setup cut up a storm. I was so impressed I bought a few of the blades and use them when I have just a few cuts to make. It's easier to clean up than a chain saw after just a few cuts.

It was really expensive back in 1990 when inverters often cost a dollar a Watt...

I had a refrigerator in the work van that was supposed to monitor voltage and stop before it killed the battery. That function didn’t work and it killed the battery several times. I could have put in a separate battery and a battery isolation switch but I just took it out and went back to the cooler. Maybe a vehicle battery is 100ah or so but I stick with the belief that you can’t discharge them very much at all and still start the vehicle.
