    Looks nice other than having to hold the trigger...how tedious. If the thing is smart enough to shut itself off when proper pressure is reached just have a button toggle it on. Inflating a tire will be such a nuisance having to kneel on the ground the whole time. 

     

    God knows who thought it was a good idea.

    Oh look, a insecure internet troll! 

    I'd recommend you, 1. Know the amount of work a person does and 2. Maybe even know the guy before you spout off some random crap that you have no idea. It really doesn't make you look good, just a immature jerk..... Thanks for your constructive criticism..... 

     

    Yet my drills aren't burned out.

    I haven't seen any photos of it next to the others available for comparison yet.

    It doesn't need one.

     

    The DeWalt is huge and the milwaukee is boxy and designed around the M12 battery, of course the makita is considerably more compact.

     

    Did you know well seasoned artists can draw to scale without a tape measure?

     

    Also, I can't understand the point of the trigger. Should be able to set it and start, I really don't like the idea of having to hold the trigger for it to run.

    I think we’re roughly a decade away, but that’s random speculation 

     

    I think that's very optimistic.

     

    When you look at companies that rely on battery technology with a massive amount of money to spend on research and implementation, you can get an idea of where the rechargable battery market is. So almost right away I thought of two companies.

     

    Nasa and Tesla, primary being Nasa.

     

    They produced a report last year looking at future battery capability for upcoming space missions and they're currently all based on lithium. There are variants, but the most commonly listed base is Li-Fe-PO4 (Lithium iron phosphate) and of course Li-Ion, namely Sony 18650 Cells.

     

    They have lithium pegged for primary energy storange until at least 2021, the JPSS2 mission.

     

    The last mission that wasn't lithium based was the Dawn mission, launched September 2007 and that was based on Nickle Hydrogen.

     

    That's 17 years after Lithium was marketed by Sony. They did have earlier missions using Lithium but it wasn't considered the gold standard until 2009 where lithium replaced every following mission as primary storage.

    At this point, I thought if NASA don't have plans for it Tesla certainly wont.

     

    As the video mentioned it was 1990(?) When sony released the first Li-ion battery cell for the mainstream; Ni-Cd was still heavily used well into the 2000's.

     

    In the video you posted, good estimates for SS batteries for the Automotive market (the most important market for SS battery tech to really help cut climate change and reduce the use of fossil fuels) are 2025-2030, and WV have been working on it since 2012.

     

    I think from now to the point where it's a mainstream concern to the point it replaces Lithium would be as much as a quarter of a decade away. It would certainly be nice to see it come beforehand given the detriment lithium mining is doing but I just can't see it.

    Demand for lithium is increasing exponentially, and it doubled in price between 2016 and 2018. According to consultancy Cairn Energy Research Advisors, the lithium ion industry is expected to grow from 100 gigawatt hours (GWh) of annual production in 2017, to almost 800 GWhs in 2027.

    There's no sign of Lithium production slowing, only increasing. Given that, 10 years is very hopeful but incredibly unlikely.

  5. Motor controller transistor. The one currently installed in the drill should have a product code which you can search to find a replacement. They're quite cheap to replace.

     

    If you have continuity at all three points it most likely is faulty.

     

    It doesn't have its own item code on the spares catalogue, however.

    Formwork decking here for suspended slabs is a maximum of 1mm thick (the most common used) I just did a search online and found the thickest to be 1.27mm (American made). Like I said it would be unmanageable on a big site to be lifting 3mm sheets. If someone in .au can point a out a link to some specs of bondek type formwork that is >1.5mm it would be great.

     

    I must have been imagining it then.

    When you talk metal deck roof what exactly do you mean? There certainly aren't any metal deck roof sheets I've seen here in Australia that are >1mm in thickness let alone 3mm thickness? You wouldn't be able to lift the sheets. 

     

     

    Depends who's lifting them or how (crane/forks) but I mean structural metal deck roofing. There are a number of different brands with a wide range of gauges depending on load rating and span.

     

    Most common one is Euroclad but I know Tata Steel do on, countless other brands. Some are 0.5mm + powder coat, some are 2mm + powder coat.

    That is cool I guess. I wonder why they took this route. You would think you could just have the 2 dummy batteries separate all the time. Maybe it the ability to remove the dummy battery will serve a purpose that Makita hasn't unveiled yet?

     

    With the ability to interchange connectivity there are many arrays possible to work with 36v and 18x2 tools the same but it will be putting out 36v not 18v so this will have to be accounted for with the X2 system.

    what is their plan for working with x2 tools? Some tools have different battery layouts. ex the x2 robot vac vs x2 rear handle circ saw. Maybe it will only work with side by side layouts?

     

    Looks to be a dummy battery for both types that connects up to the back pack.

  10. So on closer inspection it's not an inverter per se - certainly not like the DeWalt inverter.

     

    It's a 2+2 36v battery pack, purely to power 36v OPE with an increase run time but transferring weight to make it more comfortable to use over longer periods.
