I could yes easy but I need to get into the woods so no practical carting one of them with me. x

I am looking at electric and a power pack/after what British Red has mentioned. There is a lot to consider so I will take my time and learn first. D x
Red hello what dya think to this. one of theseIf you need any advice or discount codes, DM me

I was thinking to use an inverter and a 100 AH lithium battery. I have some questions
question1, what size invertor would I need?
question 2. how long would it last and will it even work well?
question 3. Should i just use my wheelbarrow to carry my 1kva suitcase generator round and power it with that?
As ever thank you for you knowledge and time spent helping me xxxx
If you are going to buy Parkside (a Lidl brand) wait till they are in store and buy there. They won't argue over warranty.
A 1600W saw will need at least a 2000W inverter but the initial surge would be better served with 3000W
A 100W Lithium battery holds 1200Wh. That's 45 mins hard operation which is 4 hours of real world work
A 1kVA generator is 1000W. Not enough power for a 1600W saw
what is the power pack you are using and what does one cost please? x
Just to add to the mix here, I had a lot of scrub to clear during COVID lock down.....as well as working.
My wife refused to let me use the chainsaw, so I bought a Bosch Blue Reciprocating saw, it was brilliant and still going strong...yes it's slower, but much safer and doesn't drain the batteries as much as a chainsaw would.
I cut through 200mm rounds quite often and doesn't hold up at all. The cut thickness is down to the blade used and if you can I would recommend the 9inch long carbide tip blades....they just keep going.
This is what I got as I wanted a one handed version
But in hindsight I should have bought the larger version for just that bit more grunt in torque.

Do you have Screwfix or Toolstation in Island or similar? Their home brand tools are great value. I’ve taken back £60 hammer drill/breakers in shocking condition that have stopped working after being treated horribly.
My best choice for a job like this is an Aferiy P210

There is a P280 model coming soon which is expandable. I'm reviewing it right now
It will depend on what type and size the trees are, @demented dale ?
Another option would be to barter someones time, I like to do as much as possible myself but if the trees are a decent size then it could well be worth getting someone to help with a petrol saw. It's surprising how much I can log up in a couple of hours and a litre of fuel with mine.
OK, I'll out with it, for working in the woods, thinning, coppicing, snedding I wouldn't dream of going down this route and I think you're being led down a path based on different use. There's all the difference in the world between homesteading and woodland management.
First, the power to run a mains electric chainsaw is not easily generated by a solar power bank at a sensible price; secondly, having a trailing mains cable (or any cable at that matter) in the midst of coppice brash and scrub is a recipe for disaster (sorry, but this is the stuff I do most days of the week).
If you want electric for use in the woods, the most practical way is to use a battery saw (buy the best you can afford), get three sets of batteries (I use Waitley, IMO as good as Makita but half the price), and use a quiet 1Kw generator to keep one set charging whilst you use the others.
Remember it's watt-hours you looking for. On a twin 18v saw (like the Makita), a 5Ah battery gives you 180 wh - so, a 1kw generator is capable of charging that in about 10 minutes. In practice it doesn't because a good charger will limit the current going into the battery - but you don't need a big generator to do this.
If you must go down the solar power bank route, for six hours of work in a wood you will only need a little over 1kwh - so a single 120Ah 12v lead acid battery fully charged will keep your saw batteries charged through a 300 or 500w inverter.
Now, all that is ignoring efficiencies - through the inverter, the battery charger, even the batteries themselves - so I would increase everything by about 1.5x
But, on anything over 250mm, I would keep a petrol saw to hand

Don't forget that although lithium leisure batteries are better than lead acid at supplying high currents, a single 100Ah lithium battery may not be enough to run a big inverter with a high load- the voltage drop on startup may cause the inverter to shut down.
This is a conclusion I am coming to. I have considered everything everyone has said. I am thinking an electric saw like below, a 200AH or even a 300AH lithium battery and an inverter. My thinking is that I would have three useful things all independent of one another and if one breaks ho hum I can still use the others. Also it is a cheaper option. I was thinking a 3000 watt inverter. I understand about cable being dangerous but I wont be in any tangled brush. I was gonna wheel it round in a barrow and work where I stop or bring logs home to cut. Here are a few asks
Question. 1.What sort of invertor, make, model, price, wattage etc would anyone recommend?
Question 2. What size battery? 200 or 300AH. there is only a £65 difference.
question 3. Can anyone see a problem in this set up.
Thanks for all input. I always enjoy asking things on here. I learn so much even f I dont use it all. xxxxx

Which is convenience and useful when there is no power or outdoor. There is a temperature sensor built in the inverter. When it is over 45℃, the fans will work automatically. When the temperature is over 75 ℃-80 ℃, the inverter will be in protection mode till it cool down.

what does anyone think of this invertor? xxxxx
Seems a bit cheap. Either it's s bargain or it's too good to be true..... and I know which of those options my money is on.
Compare the price to a Durite or Victron inverter with the same rating and you will see what I mean.

yehi think naff. i keep hearing victron. not cheap ime guessing. i will llook. thanks x
Crossover from the other thread where you mentioned a 1600W electric chainsaw.
I'd personally save and buy a Victron 2000VA inverter which delivers 1600W max continually but can happily do so all day year in year out. Best part of £500 though.
But bear in mind at 1600W it would be pulling 140A from your batteries, and max current briefly for motor starting can be a scary 300A roughly.
This needs to be within what the BMS on the lithium batteries can handle, cable needs to be adequately sized with well crimped terminals, and everything properly fused. If you're new to this kind of thing you'd likely need somebody local to help get things right and keep it safe.
There are a lot of cheap and nasty lithium leisure batteries flooding the market, I built my own but Eco-Worthy seem a good balance of quality and price.

Not a 3000W inverter, it's a poor quality item possibly capable of delivering its stated 600W continuous output until it goes pop. Sorry to be brutally honest!
